Many CalTrain bridges are over 100 years old, including the Tilton Avenue Bridge in San Mateo. As part of the San Mateo Bridges Replacement Project, CalTrain will replace the Tilton Avenue Bridge over the weekend of November 7th and 8th, with work starting at 8 PM Friday, Nov. 6, and ending at 5 AM Monday, Nov. 9.
As crews work along the bridge, the entire CalTrain system will be affected. Since track at the Tilton Avenue Bridge will be closed, northbound trains will stop at Hayward Park, and southbound trains will stop at Burlingame.
Between the two stations, SamTrans will operate a bus bridge connecting the two stops on November 7th. By November 8th, CalTrain trains will be able to single-track across the Tilton Avenue Bridge, eliminating the bus bridge.
Riders can expect delays during single-tracking across the bridge and while the bus bridge is in place. The next bridge to be replaced in San Mateo will be in December, at the Monte Diablo Bridge.
