Caltrain: San Mateo Bridges Replacement Project
Four rail bridges in the northern part of San Mateo at Tilton Avenue, Monte Diablo Avenue, Santa Inez Avenue, and Poplar Avenue were built in 1903 and do not meet current Federal and State seismic safety standards. Caltrain is launching a bridge replacement project to bring these bridges up to current standards, and will span a half-mile along the Caltrain right-of-way from Tilton Avenue to Poplar Avenue.
Phase I of this project was completed as of April 2014.
Phase I of Caltrain's San Mateo Bridges Replacement Project removed trees from Caltrain's right-of-way. It also involved a detailed
survey of the railroad corridor to determine if private fences needed to
be realigned along existing property lines.
Caltrain met with the Public Works Commission on July 10, 2013, to
give a presentation on the status of the project and respond to public
comment. For more information, please read the agenda minutes and staff report
for the meeting. Caltrain held a follow-up meeting in November 2013
responding to concerns previously brought up at the Public Works
Phase II of this project begins October 2014 and is anticipated to be completed by August 2016.
During this phase, Caltrain will raise the height of each bridge by as much as four feet in some sections. Construction began in December 2014. See Caltrain's project website
for street closures and other construction impacts or updates.
Caltrain maintains a project website
that provides a detailed overview, previous and upcoming public outreach efforts, construction updates, and other relevant information.
In December, the San Mateo Public Works Deputy Director participated in a conference call with representatives from Union Pacific, Rep. Jackie Speier's office, City of Burlingame officials, and the Federal Rail Administration. The conversation focused on evening and night train horns as freight trains travel along the Caltrain corridor. Federal Rail Administration guidelines require all trains to blow their horn through construction zones, at-grade crossings, and whenever a trespasser is spotted by the conductor in the railroad right of way. This requirement to blow a horn in the above situations must be followed at all times of the day.
A portion of the Caltrain tracks in San Mateo are considered a construction zone. This area is from Poplar Ave to Tilton Ave as Caltrain is replacing four bridges at intersections with San Mateo streets. Construction for this project is expected to last until August 2016.
Residents located near this construction zone will continue to hear train horns anytime a train travels through this section of track. Public Works staff will continue to work with U.S. Representative Speier's office as well as federal and local officials to pursue mitigation of train noise that can continue to be compliant with federal regulations.
