Town Of Moraga

Canyon Road: Bridge Reopened to Traffic 11.22.17

The Town is offering this page for all interested parties to provide available information related to the unfortunate closure of the Canyon Road Bridge that was ordered on Tuesday, April 18, 2017 and the reopening of the roadway with a temporary one-lane bridge in November 2017. 

On Friday, November 10, 2017 the Bridge Team consisting of Myers and Sons (Prime Contractor); Quincy Engineering (Bridge Designers); Harris and Associates (Construction Managers); Bigge Crane (Crane Subcontractors); Mabey Bridge (Bridge Supplier) and Town staff placed the assembled one-lane steel truss Mabey bridge upon their bridge abutments with the help of two-275 ton specialized hydraulic cranes. Myers and Sons were able to beat their original schedule for launching the Canyon Road bridge by four days and the reopening of the bridge to traffic by eight days on November 22, 2017. Please click here to view a quick time-lapse video of the Mabey bridge launching and and here to view the official Press Release for the Canyon Road bridge reopening.

In addition to the initial explanation of what has happened as shown below, all current and future staff reports and accompanying attachments will be posted on this page until the bridge is reopened. Please be patient until the bridge closure is resolved and know that the Town is committed to get the bridge reopened as soon as it can safely be accomplished and that it will be done in a fiscally responsible manner. All comments, questions, or concerns should be directed to Bob Priebe, the Town Manager at priebe@moraga.ca.us.

What Happened

On Monday April 17, 2017, Town staff was notified by EBMUD that their engineers had observed conditions that may affect the Canyon Road Bridge. Town staff responded to the bridge and saw a separation of the pavement from the south side of the bridge and soil movement away from a cement abutment at the southeast corner of the bridge. On the west side of the bridge staff noted soil separation from the paved trail toward the creek as well as cracking in the trail on both sides with a crack traversing the trail. Staff notified the Town’s on-call geotechnical consultant who responded the next morning and found the conditions noted on Monday had worsened and noted one of the support beams under the southwest corner of the bridge had been compromised. The consultants determined the damage had occurred due to active land movement from the hill above the trail area into and around the bridge location. Given the damage to the bridge support and the active land movement into it, consultants recommended closing the bridge to all vehicular, bicycle, and pedestrian traffic. The bridge was closed at 7 PM on Tuesday, April 18, 2017, and will remain closed until the land movement is stabilized to allow either the safe repair of the existing bridge structure or the safe installation of a temporary bridge. All possibilities are being examined and any action taken to re-open the bridge will be determined by the conditions of the land movement. At his time, if either the repair or placement of a temporary bridge occurs, it is anticipated that only a single lane will be open.
For a comprehensive explanation of the chronology of events associated with the bridge closure, including efforts made by all government agencies to address the emergency response needs of the Canyon community, please see the April 27, 2017 staff report and attached PowerPoint presentations.

Press Releases and Updates

Canyon Road Bridge Update – November 21, 2017

Ribbon Cutting Ceremony Moraga, California – On April 18, 2017, Canyon Road Bridge was closed when conditions of extreme peril to the safety of persons and property arose that were caused by landslide movement resulting in damage to the support structure. The Town is pleased to announce that the temporary one-lane bridge is near completion and that a ribbon cutting ceremony is scheduled to reopen Canyon Road on Wednesday, November 22, 2017 from 3:00 pm to 3:30 pm. To commemorate this occasion, a procession of police and fire vehicles will be the first to cross the bridge acknowledging the vital access needs of emergency responders at this one of only five entrance points into Town. Read more.

Canyon Road Bridge Update – October 27, 2017

The Town had to rebid the Town-rented bridge contract due to a bid protest submitted to challenge the low bidder. The second bid opening resulted in the same low bid amount and no additional protests were received. To date, Myers & Sons has installed seven foundation piles that are 48" diameter and 50' deep. The prefabricated temporary bridge will be delivered the week of November 6 and assembled like an erector set over the course of a week and then installed by pushing the assembled bridge from one side of the creek across to the other side. The final roadway approaches will then be constructed and the traffic controls installed with opening date still anticipated in late November.

Canyon Road Bridge Update – October 13, 2017

On September 28, the Town received four competitive bids to prepare the site, install abutments and landslide protection piers, and erect a Town-rented temporary one-lane bridge. Myers & Sons was the lowest bidder; however, the bid was still significantly higher than the project budget. Currently, the construction market is rife with other storm-related projects qualified for Federal disaster relief which is inflating all construction costs. On October 12, Town Council held a special meeting to allocate an additional $1.23 million to fund the construction contract and other necessary expenses. Myers & Sons specializes in bridge and emergency projects and has begun mobilizing equipment to start work. They have installed erosion control and environmental protection measures and have started excavation for the bridge abutments. Starting next week, drilling and pouring of concrete bridge supports will begin. Barring further delays, the bridge is still projected to open in late November.

Canyon Road Bridge Update – September 29, 2017

Brian Coyle, Canyon School District Boardmember, filed a Complaint and Application for a Temporary Restraining Order (TRO) and Preliminary Injunction (PI), seeking to prevent the Town from demolishing the Canyon Road Bridge. A hearing on the TRO was held on September 19 with the Town opposing the TRO. The Court denied Mr. Coyle’s request for a TRO and set a September 29 hearing on Mr. Coyle’s request for a PI. The hearing was held and the Court denied Mr. Coyle’s request for a PI. Despite the court proceedings, demolition work on the bridge has continued with the deck, stringers, and abutments removed. Total demolition of the bridge is scheduled to be completed by October 8. Work to prepare the site and install the temporary bridge is scheduled to start following the demolition work. The temporary one-lane bridge opening is still projected to occur in late November.

Canyon Road Bridge Update – September 15, 2017

The utility relocation phase is complete and demolition of the bridge will begin on Monday, September 18, with work hours Monday through Friday from 7:00 am to 7:00 pm and on Saturday and Sunday from 7:00 am to 5:00 pm. After demolition, the next phase will include construction of approaches to the temporary bridge, reinforced abutments, and deep concrete pilings to protect the area from further landslide damage. Once that is completed, the installation of the temporary bridge and one-way signaling will be installed, with re-opening expected by the end of November. Please visit the project's homepage for more information.

Canyon Road Bridge Update – August 28, 2017

Sprint is finishing their utility relocation work this week. This work is critical and must occur prior to demolishing the existing bridge. Delays in Sprint’s work has the bridge reopening rescheduled to midNovember. A bid opening for bridge demolition contract occurred on August 22, 2017. The apparent low bidder at $148,000 was below the engineer's estimate of $180,000. The bridge demolition work is expected to start by mid-September and be completed by mid-October.

Canyon Road Bridge Update – August 14, 2017

Sprint’s relocation of fiber optic lines from below the Canyon Road Bridge is progressing slower than anticipated. Due to their horizontal directional drilling operation encountering granite rock on their first two failed attempts, the third was successful; however, the reopening schedule is now delayed to mid-November. Removal of the Sprint lines is critical to allow demolition of the existing bridge.

Canyon Road Bridge Update – July 27, 2017

The Canyon Road Bridge continues to be closed to all traffic so please use alternate routes. The Town will continue to keep the public informed with updates posted on the Town’s Canyon Road Bridge website and disseminated via Nixle, NextDoor and About Town. A Frequently Asked Questions (FAQ) section will be added to the project website. Please submit any questions not addressed in the FAQ to publicworks@moraga.ca.us. Thank you for your patience.
Emergency Relief Funding Status
On June 14, 2017, the Town Council approved budget and an action plan to remove the existing damaged Canyon Road Bridge, design new bridge abutments and install a pre-fabricated one-lane truss bridge with an attached pedestrian walkway over the Moraga Creek. This will re-establish essential traffic along Canyon Road for emergency responders and the public. This one-lane bridge will be in use until a permanent two-lane bridge with pedestrian walkway can be built using funding from Caltrans Highway Bridge Program funds.
On July 24, 2017 Caltrans staff notified the Town of Moraga that the Federal Highway Administration’s (FHWA) Emergency Relief Program staff approved the Town’s Damage Assessment Form (DAF). The DAF itemizes what disaster damage has occurred and includes a preliminary $2.06 million cost estimate to implement the Town’s one-lane bridge plan. Now that FHWA has approved the DAF for the project, Town staff will begin submitting supporting documentation to Caltrans, who administers the project for FHWA, and for Caltrans to allocate a project budget for reimbursable costs.
Utilities Relocation Work Update
AT&T (telecommunications utility) is finishing their relocation of overhead utility lines that would have been in conflict with the construction of the temporary one-lane bridge. Sprint mobilized their equipment on site last week and began operations to install new fiber optic conduits approximately 30 feet underneath Moraga Creek’s creekbed to relocate their lines from their attachment to the Canyon Road Bridge. Demolition of the existing bridge cannot begin until Sprint has completed their necessary work. Work is scheduled to occur Monday through Friday from 8:00 am to 5:00 pm, except for any unplanned emergency work. Canyon Road vehicular and pedestrian access to and from Constance Place will remain open.

Canyon Road Bridge Update – July 13, 2017

The Canyon Road Bridge continues to be closed to all traffic so please use alternate routes. The Town will continue to keep the public informed with updates posted on the Town’s Canyon Road Bridge website and disseminated via Nixle, NextDoor and About Town. A Frequently Asked Questions (FAQ) section will be added to the project website. Please submit any questions not addressed in the FAQ to publicworks@moraga.ca.us. Thank you for your patience.
Utilities Relocation Work Update
Sprint utility has postponed start of work from July 17 to 24 to install new fiber optic conduits approximately 30 feet underneath the Moraga creek bed to relocate their lines from beneath Canyon Road Bridge. Sprint will be using the horizontal directional drilling (HDD) method which will not require environmental permitting thus expediting their work. Work is scheduled to occur Monday through Friday from 8:00 am to 5:00 pm, except for any unplanned emergency work.
Sprint has also notified the Town that their work will take six (6) weeks rather than the reported four (4) weeks as announced in the July 7, 2017 Press Release. Canyon Road vehicular and pedestrian access to and from Constance Place will remain open. Demolition of the existing bridge cannot begin until Sprint has completed their necessary work which means that the anticipated opening of the temporary bridge to traffic is now delayed to early November 2017.

Temporary Bridge Engineering Design Update
As directed by Town Council, a one-lane, 150-foot long, temporary bridge will be installed this year to provide access until a permanent replacement bridge is constructed, likely to occur in 2019. The bridge reopening is a very complex project requiring extensive environmental approvals from nine outside agencies to work within Moraga Creek, which is a natural habitat for multiple endangered species.
There are four major construction phases for the installation of the temporary bridge: 1) relocation of utilities; 2) removal of the current bridge that has suffered damage caused by the landslide 3) construction of roadway approaches to the temporary bridge, reinforced abutments and deep concrete pilings to protect against the landslide; and 4) installation of the temporary bridge and a one-way traffic control signal system. Project work is expected to begin the week of July 17, contingent on receiving the necessary environmental approvals.
The Bridge Team is currently reviewing the 90% submittal of the existing bridge demolition plans and 30% submittal of the temporary bridge installation plans with the goal to finalize these separate plan sets and bid the work out to contractor(s). The removal of the existing bridge is anticipated to be completed by early September 2017 and the temporary bridge opened to traffic by mid October 2017. Any delays in utility relocation or permitting process can directly impact the overall project schedule.
Utilities Relocation Work Update
AT&T and Sprint both have major utility lines that need to be relocated prior to removal of the bridge. AT&T is nearing completion of their overhead relocation work. On July 17, Sprint is scheduled to begin installing new conduits underneath the creek bed to relocate their lines from off the bridge. Sprint will be using the horizontal directional drilling (HDD) method to expedite and complete their work within 4 weeks. Demolition of the existing bridge cannot begin until Sprint has completed their necessary work and any delays can directly impact the opening of the temporary bridge to traffic.

Canyon Road Bridge Update - June 29, 2017

On June 14, 2017 at the regularly scheduled Town Council meeting, Town staff presented alternatives for reopening the Canyon Road Bridge detailing associated costs, scheduling and necessary coordination efforts with the permanent bridge replacement project. The Town Council allocated $2.06 million to complete the engineering design and construction of a one-lane long span bridge with an attached sidewalk over the Moraga Creek, reopening Canyon Road for emergency and community traffic. The staff report and attachments are available to the public on the Town’s website. A video recording of the Town Council meeting can be viewed on LiveStream video.
The engineering for the temporary bridge design is being completed by Quincy Engineering and their experienced subconsultants: Hultgren-Tillis Engineers (geotechnical engineering); NV5 (bridge, survey, utility and right-of-way engineering); and LSA (environmental compliance and permitting consultants). The existing damaged 100 foo long, two-lane bridge will be replaced by a one-lane, 150 foot long bridge. The bridge will span the recent landslide area on the southern side and will require deep bridge pilings on this side to secure the new temporary bridge from future land movement.
The temporary bridge is expected to be open for traffic in late September or early October 2017. The bridge reopening is a very complex project requiring extensive environmental approval and permitting to work over the Moraga Creek, a natural habitat for multiple endangered species. The major project tasks and milestones include: • Obtaining environmental clearances and permitting from nine different agencies and protecting and maintaining flows in the creek;
• Obtaining right-of-way from East Bay Municipal Utility District for placement of the temporary bridge;
• Relocating of major fiber optic telecommunication lines from their attachment to the bridge to a new deep conduit bored deep under Moraga Creek;
• Constructing of multiple 50 foot deep reinforced concrete pilings to protect bridge abutments on the southern side against future land movement;
• Constructing a new long span one-lane bridge and roadway transitions to the bridge; and
• Lastly, installing a traffic light system to control one-way traffic across the bridge.

Canyon Road Bridge Update - June 14, 2017

On June 14, 2017, (tonight) at 7:00 pm at the regularly scheduled Town Council meeting, 335 Rheem Boulevard, staff will be presenting alternatives for reopening the Canyon Road Bridge detailing associated costs, scheduling and any coordination efforts with the permanent bridge replacement project.
The staff report and attachments are available to the public on the Town’s website. Staff anticipates a full Council Chambers and encourages anyone interested in learning more about the status of the bridge reopening to watch LiveStream video of the Council Meeting or Comcast channel 26.

Canyon Road Bridge Update - June 9, 2017

Final fieldwork and analysis has been completed to make a formal presentation and recommendation to the Moraga Town Council on June 14, 2017 at 7:00 pm, in the Council Chambers at 335 Rheem Boulevard, regarding alternatives for re-opening the bridge. The presentation from staff will include a summary of all different alternatives and aspects of the bridge re-opening project, and among other things, information on anticipated costs and potential funding sources. The cost descriptions will include relocating existing utilities, demolishing the existing damaged bridge, installing bridge foundations, drilling 50’ deep piers on the west side of the bridge to protect it from the landslide, erecting temporary traffic signals to operate one lane of traffic, installing required creek protection, and providing engineering and construction management services to implement all required work. The staff report and attachments are available to the public on the Town’s website.
Anyone interested in learning more about the status of the bridge reopening can either attend or watch LiveStream video of the Council Meeting

Canyon Road Bridge Update - June 1, 2017

On May 30, 2017, the Town received correspondence from the Canyon School District which included a press release and a copy of a “Proclamation of a Local Emergency Within Canyon School District.” Both documents (available on the Canyon Road Bridge webpage) contain gross misstatements of fact and are not supportive of the work the Town of Moraga is trying to accomplish. The Town wants everyone in all affected communities, but especially in the community of Canyon, to understand that the Town of Moraga, since the initial date of April 17, 2017, when the Town first became aware of potential damage to the Canyon Road Bridge, has hired and worked with state licensed and certified engineers and consultants to assess the condition of the bridge, to determine the need to close the bridge to protect the public, to determine what caused the damage to the bridge, and to plan the best course of action to re-open the bridge as quickly as possible. The Town is considering spending more than $2 million to attempt to re-open the bridge in the short term only because the Town is concerned for and cares about the community of Canyon. If there were no residents in Canyon, the Town might let the bridge remain closed until the bridge replacement project could begin, which would be late in 2018 at the soonest. Any suggestion by the Canyon School District that the Town is not doing everything it can to get the bridge re-opened is blatantly false and counterproductive to the mission at hand. Final fieldwork and analysis is being completed to make a formal presentation and recommendation to the Moraga Town Council on June 14, 2017 at 7:00 pm, in the Council Chambers at 335 Rheem Boulevard, regarding options for re-opening the bridge. The presentation from staff will include a summary of all different options and aspects of the bridge re-opening project, and among other things, information on anticipated costs and potential funding sources. The cost descriptions will include relocating existing utilities, demolishing the existing damaged bridge, installing bridge foundations, drilling 50’ deep piers on the west side of the bridge to protect it from the moving landslide, erecting temporary traffic signals to operate one lane of traffic, installing required creek protection, and providing engineering and construction management services to implement all required work. The staff report and attachments will be available to the public on the Town’s website on Friday evening, June 9, 2017. Anyone interested in learning more about the status of the bridge reopening can either attend or watch LiveStream video of the Council Meeting.

Canyon Road Bridge Update - May 25, 2017

On June 14, 2017, at 7:00 pm at the regularly scheduled Town Council meeting, staff will be presenting possible options for reopening the Canyon Road Bridge detailing associated costs, scheduling and any potential impacts to permanent bridge replacement. Anyone interested in learning more about the status of the bridge reopening can either attend or watch LiveStream video of the Council Meeting.
Staff continues to pursue grant reimbursement funding for the emergency bridge reopening from: 1) Federal Highway Administration (FHWA) (administered through the California Department of Transportation (Caltrans)) and 2) Federal Emergency Management Agency (FEMA) (administered through the California Office of Emergency Services (OES)). The approval process is very lengthy and funding would be on a reimbursement basis, as their respective program funding becomes available (could be years later) to pay a portion of the Town eligible expenses. It is important to note that the Town would be responsible for the upfront bridge reopening.
The Town received Caltrans’ initial review comments for our FHWA Emergency Relief program application. Staff is preparing requested responses and supporting documentation. Staff will meet separately with FEMA and OES staff to discuss the Town’s FEMA emergency grant funding application.
Separately, Caltrans’ Environmental Division has nearly finalized the National Environmental Protection Act (NEPA) permitting requirements for the permanent bridge replacement project. Caltrans has agreed to work with all parties involved in their Federal environmental process to modify the project scope to include the work of the emergency opening of the bridge, saving valuable time. The Town will still need to obtain separate environmental permitting for the bridge reopening work from five other Federal, State and local environmental agencies.
The bridge reopening timeline is yet to be determined, but could still take months to get all permits approved; stabilization work completed; the existing bridge demolished; and a temporary bridge purchased, delivered, and built. Please visit the Canyon Road Bridge webpage for the latest information. The Town will continue to keep the public informed with updates posted on the Town website and disseminated via Nixle, NextDoor and About Town. Thank you for your continued patience.

Canyon Road Bridge Update - May 18, 2017

The Canyon Road Bridge continues to be closed to all traffic. Please use alternate routes. The Town will continue to provide information and updates as they become available.
Engineers have installed additional inclinometers around the bridge to measure adjacent land movement and determine area and depth of the landslide. Additionally, the Town recently finalized an agreement with EBMUD to share inclinometer data to get a broader perspective of the movement in the area. Based on current information, the most viable option is to remove the existing bridge (still in the path of the slowly moving landslide) and construct a temporary 160’ one-lane, free-standing bridge to span over the landslide area. The temporary bridge will need 50 foot deep foundations on the west side of the Moraga Creek to protect the bridge against future land movement. The initial estimate for design, purchase, and installation of a temporary bridge is $2.6 million. The Town continues to research all options that will accomplish the goal, but at a lower cost. The Town has contacted other California jurisdictions to see if a long-span bridge that meets the length and alignment requirements is available to borrow, rent, or buy to reduce costs.
The Town has submitted requests for emergency funding to two sources: 1) Federal Highway Administration (FHWA) (administered through the California Department of Transportation (Caltrans)) and 2) Federal Emergency Management Agency (FEMA) (administered through the California Office of Emergency Services). These applications are being evaluated to see if the Town qualifies for any emergency opening and repair funding grants. The Town’s application to Caltrans has been approved and has been forwarded to FHWA (funding source) for project scope approval. If FHWA approves the project scope then a field meeting will be scheduled to develop detailed scope and funding amount for the project. On a parallel track, staff is meeting with FEMA’s emergency disaster representatives to review the Town’s submitted funding application. The Town has also submitted an insurance claim that could partially fund the replacement if no other outside funding is received.
The bridge reopening timeline is yet to be determined, but could still take months to get all permits approved; stabilization work completed; the existing bridge demolished; and a temporary bridge purchased, delivered, and built. The Town will continue to keep the public informed with updates posted on the Town website and disseminated via Nixle, NextDoor and About Town. Thank you for your continued patience.

Canyon Road Bridge Update - May 11, 2017

The Canyon Road Bridge continues to be closed to all traffic. Please use alternate routes. The Town will continue to provide information and updates as they become available.
The Canyon Road Bridge re-opening project has been taken over by Edric Kwan, the Town’s Public Works Director. Edric is working with Town staff and consultants to address all of the issues related to re-opening the bridge. The option staff is currently exploring to present to the Town Council is to remove the existing bridge and construct a temporary 160’ one-lane, free standing bridge. The temporary bridge would be located in a position that would allow a new permanent bridge to be constructed east of the temporary bridge.
The initial estimate for design, purchase and installation of a temporary bridge is $2.6 million. The Town continues to research all options that will accomplish the goal, but at lower cost. The Town has submitted a request for emergency funding through Caltrans and the California Office of Emergency Services. The request is being evaluated to see if the Town qualifies for any funding programs. If approved, funds will pay for a portion of the total cost, but as in the case with the sinkhole, the Town will have to pay upfront costs and wait for reimbursement. The Town has also submitted a claim to the Town’s insurance carrier, who is making their assessment of damage and potential coverage. The Town’s policy requires a $500,000 deductible with a maximum coverage of $2 million in property loss. Staff recommendations on a temporary bridge or other options will be presented to the Town Council at a public meeting for their approval and authorization of funding.
The timeline is still being developed, and is subject to change based on the ongoing consideration of all options, but it could take months to get all permits and approvals; stabilization work completed; removal of the existing bridge; and a temporary bridge purchased, delivered, and built. The Town will continue to keep the public informed at least weekly, with updates posted on the Town website and disseminated via Nixle, NextDoor and About Town.

Canyon Road Bridge Update - May 4, 2017

The Canyon Road Bridge continues to be closed to all traffic. Please use alternate routes.
A special Town Council meeting was held on Thursday April 27, 2017 to provide an update on the bridge closure, declare a local emergency, and authorize an initial amount of $500,000 to reopen the road. The Moraga-Orinda Fire District provided an update on how to maintain emergency services for the community of Canyon and surrounding areas. Town staff and their team of engineers, including geotechnical and structural engineers, provided a briefing on the detrimental structural impacts to the bridge from the adjacent landslide, which necessitated the closure based on public safety considerations. The meeting was live-streamed and a recorded copy can be accessed via the Town's website.
Town bridge and geotechnical engineers have installed slope inclinometers to measure lateral movement of the adjacent landslide. They have determined that the slide is significant and relatively deep near the bridge, up to 28 feet below the ground. The slope inclinometer readings over this last week continue to show additional land movement pushing into the bridge. With this information, the bridge engineers have developed potential options to: 1) stabilize the slide and existing bridge; or 2) remove the existing bridge and replace with a specialized manufactured temporary bridge. In both cases, below ground deep pilings will need to be designed to protect the bridge by resisting future land movement. Next week, the bridge engineers will prepare a preliminary construction cost estimate and schedule for reopening the road.
The Town continues to publicize this bridge closure through media outlets and electronic resources, advise bicycle user groups through list serves, and request that traffic apps and maps reflect the closure. Please help spread the word by passing this information to anyone you know who may travel through the area. The Town will continue to provide information and updates as they become available. Please visit the Canyon Road Bridge webpage for more information. Thank you for your patience as the Town continues its efforts to reopen the bridge.

Town Hall Meeting on Canyon Road Bridge Closure - April 27, 2017

On Thursday, April 27, a special Town Council meeting was held to take formal action to declare a local emergency and to appropriate an initial $500,000 to fund the investigative and initial work phase to reopen the Canyon Road Bridge in some manner. Land movement into the structure of the bridge necessitated closure of the bridge on Tuesday, April 18. A geotechnical team has been working continually since that date to gather data on the land movement and to prepare a plan and cost estimate to stabilize the area which is critical to either repair the existing bridge structure or install a temporary bridge. At the special meeting, (see meeting on Livestream) staff reported on the chronology of events associated with the bridge closure with a presentation of photos by the geotechnical team; the emergency response plans for service to Canyon, including a presentation by MOFD Chief Healy; and the response of government agencies to the needs of the Canyon community. The special meeting was well attended and several members of the public gave their observations and concerns to the Council for consideration. Please be mindful and remind friends and neighbors that Canyon Road remains closed between Constance Place and the EBMUD Valle Vista Staging Area. The closure applies to motor vehicles, bicycles, horses and pedestrians and violators will be cited. Please be patient and avoid the area until the bridge can be reopened. Thank you for your cooperation.

Canyon Road Bridge Update - April 24, 2017

Canyon Road, between Constance Place and the Valle Vista Staging Area, remains closed due to structural issues with the bridge. The road is closed to ALL TRAFFIC - motor vehicles, bicycles, horses and pedestrians. Please do not access the closed area as violators will be cited.
The Town will be holding a public meeting to discuss the road and bridge closure on Thursday April 27, 2017, 6:00 p.m., in the Council Chambers at 335 Rheem Boulevard. The meeting will also be live-streamed, which can be accessed via the Town's website and allows people to watch from home.
The Town has a team of engineers, including geotechnical and structural engineers, who are studying the issues and working to come up with a solution. The structural integrity of the current bridge is being affected by earth movement. Although the bridge looks normal and has been functioning as designed, this earth movement is causing problems and adversely affecting the support structure under the bridge. If this continues to occur or if there is a rapid earth movement, the bridge can fail without warning and anyone on or around the bridge would be in danger. When the Town was advised of this risk to public safety, the bridge was closed.
The Town has publicized this closure through media outlets and electronic resources, advised bicycle user groups and has requested that traffic apps and maps reflect the closure. Please help us spread the word by passing this information to anyone you know who may travel through the area. The Town will continue to provide information and updates as they are available. Thank you for your patience as the Town continues to work to identify the cause of this issue and develop the best solution for all involved.

Canyon Road Bridge Closure - April 18, 2017

The Canyon Road bridge that connects Moraga with the community of Canyon and the Redwood Canyon area, will be closed at 7:00 p.m. tonight (Tuesday, April 18) for an indefinite period of time. The bridge will be closed to all traffic, including vehicular, bicycle and pedestrian.
Canyon Road will be closed between Constance Place in Moraga and the EBMUD Valle Vista Staging area. Commute traffic between Moraga and Oakland will be affected.
The area around the bridge was checked by geotechnical engineers due to a nearby land slide and earth movement. Both the geotechnical engineers and structural engineers determined that the bridge has suffered structural damage as a result of the earth movement and recommended closure due to the danger of collapse.
The Town is coordinating with the Moraga-Orinda Fire District and other agencies to finalize the contingency plan for emergency responses into the community of Canyon.
The Town will continue to monitor the situation and provide updates as needed.
