Mission/Warren Area Improvements



VTA, in partnership with the Alameda County Transportation Commission (Alameda CTC), City of Fremont, Federal Highway Administration and Caltrans, have common goals of easing congestion, enhancing safety/access and improving local traffic circulation. These improvements benefit the community and the region by expanding mobility in south Alameda County, building critical transportation infrastructure and helping to clear and prepare the corridor for VTA's BART Silicon Valley Extension.

Warren Avenue

  • Warren Avenue will be lowered underneath the existing UPRR and future BART tracks, enhancing safety and reducing congestion for pedestrians, cyclists and vehicle occupants near the I-880 interchange in southern Fremont.
  • A new UPRR bridge and future BART bridge will be constructed allowing both to be grade-separated from Warren Avenue.

Mission Boulevard

  • Construction will include widening Mission Boulevard to Warm Springs Boulevard and new on-and-off ramps to and from Kato Road.
  • A BART bridge will be constructed allowing BART trains to pass over Mission Boulevard separated from traffic.
  • A single 2-track UPRR bridge will be constructed over Mission Boulevard.

Rail Facility Improvements

  • A new bridge over Warren Avenue will be constructed to provide access improvements to the existing facility allowing for continued transfer operations of cargo between trucks and railcars.
  • UPRR track relocation will clear corridor for VTA's BART Silicon Valley Extension.


  • Start of Construction: Summer 2012
  • Completion of Construction: Spring 2015
