Caltrain construction and maintenance for July 16-22

Written by jrood

Caltrain construction and maintenance will begin July 16 at multiple station locations. The $147 million San Bruno Grade Separation project, beginning July 16, will elevate the Caltrain tracks above three existing at-grade street crossings at San Bruno, San Mateo and Angus avenues in California. A new-elevated Caltrain station will also be constructed between San Bruno and San Mateo avenues. Day work on the project will include pavement work along Huntington Avenue, preparation for signal system upgrades the following weekend, track work, excavation, potholing, drainage improvements at the temporary station, construction of retaining walls for the temporary station, and sanitary sewer and utility relocations. Night work on the project will include signal system upgrades, excavation, drainage improvements for the shoofly, construction of retaining walls for the temporary station, preparation for signal system improvements the following weekend and relocation and installation of traffic signals at San Mateo Avenue, as well as pedestrian and traffic gates on San Bruno and Angus avenues and at the San Mateo and Huntington avenues intersection. A Caltrain test train will run July 22 through July 25 between the South San Francisco and Millbrae stations to evaluate the operational quality of the upgrade signal system. Work on the Santa Clara Station Improvement project in Santa Clara, Calif., will begin July 18. It will add a new wider, longer center-boarding platform and extend the southern platform 150 feet. The work will include continued construction on the pedestrian underpass connecting the north- and southbound platforms, which will allow two trains to pass through the station at the same time and improve safety for pedestrians in the station. Caltrain's Station Security Improvements project at the San Francisco station will begin July 18 when crews will saw cut concrete and install bollards there. These improvements are part of a project to enhance security at three Caltrain stations. Crews will continue building bridge support structures and backfilling areas along the tracks by Jerrold Avenue and Rankin Street in San Francisco on July 18 as well. Caltrain will continue retrofitting four rail bridges for the San Mateo Bridges Rehabilitation project in San Mateo, Calif., July 18. The project includes improvements to the bridges that cross Poplar, Santa Inez, Monte Diablo and Tilton avenues. Crews will continue drilling foundation piles under the bridges and continue installing columns for the bridges and building temporary support structures. The San Jose Diridon Station Improvements project will begin July 16. Track construction will take place on July 18. The signal system upgrades that will be constructed at both ends of the San Jose Diridon terminal will improve train operations by allowing quicker train movement in and out of the terminal. Caltrain will also perform routine maintenance at several locations during the week of July 25.
