A proposed replacement bridge over San Francisquito Creek and U.S. Highway 101 between University Avenue and Embarcadero Road will be discussed at a community meeting on Wednesday (June 15).
The bridge replacement would tear down the existing structure and replace it with a new bridge designed to increase water flow from the creek.
The new bridge would increase 46 feet in length, from 80 feet to 126 feet and would be widened 12 feet, from 232 feet to 244 feet, according to a Caltrans bridge-replacement report. The structure would not take any property and would not increase traffic, according to Caltrans.
Portions of West Bayshore and East Bayshore roads would also be rebuilt and widened and a sound wall along West Bayshore would be moved to accommodate the wider road, according to the report.
The bridge was originally to be widened to better accommodate the additional lanes for the Auxiliary Lanes project, designed to improve traffic flow along the 101 corridor. But engineers determined the existing bridge is deteriorated and should be replaced, according to Caltrans.
The original freeway portion of the bridge was built in 1931. The freeway was widened in 1957, when East Bayshore and West Bayshore roads were also added.
Recent inspections found significant structural deterioration, including large vertical and horizontal cracks, according to the report.
The replacement is expected to improve the bridge's capacity to handle creek waters by 20 percent, according to a preliminary hydraulic report, and would improve the movement of water in a 100-year flood.
The project would not result in significant or adverse impacts of the existing 100-year floodplain, the bridge-replacement report noted, however. Portions of 101 would still be inundated during an extreme flood event.
Wednesday's meeting will be held at the East Palo Alto City Hall Community Room, 2415 University Ave., East Palo Alto, from 6:30 to 8:30 p.m. Maps of the project will be available for viewing.
The Initial Study with Proposed Negative Declaration/Environmental Assessment can be viewed at Initial Study.
The documents are also available at Palo Alto Main Library, 213 Newell Road, Palo Alto, and East Palo Alto Public Library, 2415 University Ave., East Palo Alto.
Maps and additional project studies are available at Caltrans District 4 Office, 111 Grand Ave., Oakland, on weekdays from 8 a.m. to 5 p.m.
