Document Description
This project proposes to replace the existing bridge baluster railings with bridge concrete barrier and upgrade the sidewalks on the Hillsdale Boulevard Overcrossing (Br. No. 35-0198) in the City of San Mateo in San Mateo County on State Route 82. The purpose of this project is to improve the existing bridge railings to meet current Caltrans standards. This project is needed because the deteriorated bridge railings may not withstand impacts from vehicles. Its weakened condition may lead to sudden catastrophic collapse. On each side of the bridge, the project will remove the existing steel baluster railing and sidewalk. New bridge concrete barrier type 732W with type 6 chain link fence and sidewalk will be constructed.
