Caltrain earlier this week announced it has installed a rail bridge at 28th Avenue in San Mateo, California, marking the second rail bridge to be constructed this summer as part of the $180 million 25th Avenue grade separation project.
In July, Caltrain installed a rail bridge over 25th Avenue, and is now preparing for its third and final rail bridge across 31st Avenue in the coming weeks. Crews also will continue work on the mechanically stabilized earth walls that will hold up the track between bridges.
Construction on the project began in 2017 in order to improve safety and traffic flow in the area.
Expected to be completed in 2021, the project is funded by the city, state, California High-Speed Rail Authority and by San Mateo County Measure A funds.
