Guadalupe Bridge Replacement Project

Sign up for Weekly Construction Notices

Caltrain operates on two tracks, northbound and southbound, over the Guadalupe River in San Jose, just north of Tamien Station.

The northbound track is on a wooden trestle bridge constructed in 1935 and the southbound track is on a concrete bridge constructed in 1990. Each bridge requires different levels of construction. 

The bridges are located in an area of high erosion and are at risk of bank failure during storm events. Riverbank failures have occurred in several previous years, requiring emergency stabilization measures. To address these safety issues and protect the rail bridges, the project will conduct channel work, including erosion prevention, and complete the necessary enhancements to the rail bridges to maintain safe and reliable operations for all users. 

In addition to Caltrain's passenger service, the railroad bridges are used by Union Pacific Railroad (UPRR) freight service, Amtrak passenger service, and by the Altamont Commuter Express (ACE) and Capitol Corridor.  

Northbound Bridge (MT-1): 

  • The 1935 wooden northbound bridge has been damaged by multiple fires and will be replaced with a new concrete structure to meet current railroad structural design standards and seismic criteria. The replacement bridge structure will be 265 feet. 

Southbound Bridge (MT-2):

  • Because the southbound bridge was constructed in 1990, full replacement is not necessary; however, the southern end of the bridge structure will be extended due to river flow speeds and riverbank erosion. The bridge will be 250 feet with the extension. 

September marked a significant milestone as the MT2 bridge was successfully erected, bringing us one step closer to restoring passenger service on the bridge.

Project Total: $63.3 Million 

While most of the construction work will be completed during the day, night and weekend work will sometimes be required to maintain rail operations. Caltrain will continue to operate during the construction periods and single tracking may occur. 

The majority of work will be done during the day with typical work hours Monday to Friday, 7:30 am to 4:00 pm. Construction activities include vegetation work, removal of bridge/segments, utility relocation, grading, drilling/pile work, concrete work, bridge installation, and track removal and replacement. We apologize for any inconvenience the construction may cause. 

Caltrain will follow all applicable environmental regulations and will work to mitigate any potential environmental impacts to the area before, during, and after construction.
