The Canyon Road bridge over the West Branch San Leandro Creek (Br. No. 28C0137) is located approximately 2.4 miles north of the Alameda County line in the Town of Moraga. The alignment of Canyon Road at the bridge site is threaded between constraining features on both sides of the bridge. The west side includes the Lafayette-Moraga Regional Trail, maintained by East Bay Regional Park District, a hillside, a fire lane access trail, private residences and numerous utilities. The east side of the bridge is limited by the banks of the creek itself and Joaquin Moraga Intermediate School. The existing bridge is structurally deficient and needs replacement.
