WHAT:  Caltrain will be replacing the 112-year-old Santa Inez Avenue rail bridge as part of the San Mateo Bridges Replacement Project.

WHEN & WHERE:  The bridge replacement will require the complete shutdown of Santa Inez Avenue and several surrounding streets with continuous weekend track work beginning at 8 p.m. on Friday, Feb. 26, through 5 a.m. on Monday, Feb. 29. Construction activity includes removing the old bridge structure and rolling in the new bridge.

Because of the mandatory track closure that weekend, Caltrain will operate a bus bridge using SamTrans bus service between its Hayward Park and Burlingame stations on Saturday, Feb. 27, to accommodate the replacement of the bridge. All passengers traveling through San Mateo on Saturday will be required to board buses between the Hayward Park and Burlingame stations. By Sunday, Feb. 28, Caltrain is expected to be back in service and trains will be using one track, known as single-tracking, through the project area to provide service.

Information on the temporary service change will appear on the visual message signs at stations and conductors will be making regular announcements onboard trains as well. In addition, ambassadors will be at all three stations Hayward Park, San Mateo and Burlingame to assist people.

Caltrain will undertake this same process for the remaining Poplar Avenue Bridge, which is tentatively scheduled for replacement in April 2016. For a copy of the bus bridge map, visit www.caltrain.com/busbridge.

WHY:  Caltrain, in cooperation with the City of San Mateo, is replacing the four century old rail bridges located at Tilton, Monte Diablo, Santa Inez and Poplar Avenues, which no longer meet current seismic safety standards.

The project will ensure that the aging bridges are safe and equipped to meet the region’s future transportation needs, including new electrified rail service, and improved traffic flow on city streets.  The project is expected to be complete by October 2016.




About Caltrain: Owned and operated by the Peninsula Corridor Joint Powers Board, Caltrain provides commuter rail service from San Francisco to San Jose, with limited commute service to Gilroy. Caltrain has enjoyed more than five years of consecutive monthly ridership increases, surpassing more than 60,000 average weekday riders earlier this year. While the Joint Powers Board assumed operating responsibilities for the service in 1992, the railroad celebrated 150 years of continuous passenger service in 2014. Planning for the next 150 years of Peninsula rail service, Caltrain is on pace to electrify the corridor, reduce diesel emissions by 97 percent by 2040  and add more service to more stations.
