Geary Road Bridge Project

Project Update

The new Geary Road Bridge is open and ready for use! The new 150-foot-long concrete and weathered-steel bridge replaced an old bridge that was unable to support the weight of large vehicles that use it regularly. It crosses Alameda Creek, downstream of Calaveras and Alameda Creek Diversion Dams, and it is located within the East Bay Regional Park District’s Sunol Ohlone Wilderness Park leased lands. This new bridge will protect Alameda Creek at this location by eliminating the need for large vehicles to drive through the creek’s low-water crossing. Planting and restoration of the site are underway.

Project Background
Working closely with the East Bay Regional Park District, the San Francisco Public Utilities Commission will replace the existing unreliable wooden Geary Road Bridge with a new concrete and steel bridge. The load capacity of the existing bridge is 10 tons, which precludes heavy vehicles such as fire trucks, construction equipment, and livestock trailers from using the bridge. When stream flow conditions allow, heavy vehicles currently cross the creek at a low-water crossing near the existing bridge. The new bridge will accommodate a 63-ton load, result in improved bridge reliability and safety, and eliminate the need for vehicles driving through Alameda Creek at the low-water crossing. The new bridge is of a similar scale to the existing bridge, and would include a single lane spanning approximately 150 feet over Alameda Creek.

Construction of the project will include installation of a temporary creek crossing; removal of the existing bridge; constructing the new bridge with abutments and piers; replacing access roads and culverts; and performing site restoration and native habitat enhancement.

The project is located at the end of Geary Road, where it crosses Alameda Creek and connects to Camp Ohlone Road in the Sunol Regional Wilderness area. This project is approximately 6 miles south of the intersection of Calaveras Road and Interstate 680, and approximately 3 miles south of the intersection of Calaveras Road and Geary Road. Vehicle access to the bridge is controlled by locked gates.
