Montague Expressway/South Milpitas Boulevard Improvement Project


The Santa Clara Valley Transportation Authority (VTA) is partnering with Santa Clara County (County), the Santa Clara Valley Water District (SCVWD) and the City of Milpitas to implement the Montague Expressway/South Milpitas Boulevard Improvement Project. The improvements are being put in place to ensure accessibility to the future Milpitas BART Station and area developments, alleviate traffic concerns in the surrounding area and prepare against potential flooding from Berryessa Creek.

Berryessa Creek flood protection improvements:

  • In order to protect the community from potential flooding, loss of utilities and impacts to roadways and transit services, Berryessa Creek will be widened and reengineered to accommodate major flooding events.
  • At the intersection of South Milpitas Boulevard and Montague Expressway, the existing concrete creek box will be replaced with a new concrete bridge to allow for increased capacity of the creek. The intersection will be elevated to accommodate the new flood control improvements within Berryessa Creek.

Montague Expressway roadway modifications:

  • An additional westbound HOV lane will be added from I680 to Capitol Avenue on Montague Expressway.
  • Sidewalks will be constructed along the expressway in areas where there are current sidewalk gaps.
Extension of South Milpitas Boulevard to Capitol Avenue
  • South Milpitas Boulevard will be extended from Montague Expressway to Capitol Avenue. This new roadway will provide an additional point of access to the Milpitas BART Station and provide new access for development in the area. This will alleviate traffic congestion at the Great Mall Parkway/Capitol Avenue and Montague Expressway intersection.
