Canyon Road Bridge Replacement Project
Resident Engineer Inspector: Brandon Hays, Harris and Associates (760) 846-5842
Project Manager: Sharon Chan, Town of Moraga (925) 888-7028
Contractor: Joe Burgoon, Bridgeway Civil Constructors, Inc.
The Canyon Road bridge over the West Branch of San Leandro Creek (also called Moraga Creek) is located within the Town of Moraga, just south of Constance Place and north of the Contra Costa County line. The bridge was originally constructed in 1936, is approximately 104 feet long, 24 feet wide and carries two lanes of traffic. The existing bridge is structurally deficient with a sufficiency rating of 48.8. A sufficiency rating of less than 50 qualifies a bridge for replacement according to the funding guidelines for the Federal Highway Bridge Program. The existing concrete deck is heavily abraded, rough, uneven throughout with spalling at the joints, and has pattern cracks throughout. Several of the wooden bridge railings and posts are broken and rotten.
The existing bridge geometry is a safety issue for bicyclists and pedestrians who use the bridge to access a heavily used bike/pedestrian trail, the Lafayette-Moraga Regional Trail (maintained by East Bay Regional Park District), that serves recreational cyclists as well as nearby residents that walk to Joaquin Moraga Intermediate School adjacent to the northeast approach to the bridge.
The Town is replacing the existing bridge with a new clear-span bridge, approximately 120 feet long and 48 feet wide. The new bridge will accommodate two 12-foot travel lanes and two 8-foot wide shoulders on both sides, serving as bike lanes, and one 5-foot wide sidewalk to accommodate pedestrians on the west side of the bridge.
