State Route 85 and US 101 Express Lanes Projects

VTA, as part of its Silicon Valley Express Lanes Program, has combined the SR 85 and US 101 Express Lanes projects in Phases 3 and 4.

US 101 in Santa Clara County extends 52 miles from San Benito County to San Mateo County, providing north and south gateways into Silicon Valley. This stretch of highway serves as an important trade corridor between the Central Valley, Central Coast, and the San Francisco Bay Area. The highway also connects commuters to technology and professional service industries in Santa Clara County.

SR 85 highway extends from the US 101 interchange in San Jose to the US 101 interchange in Mountain View.  The highway connects commuters from San Jose, Los Gatos, Cupertino, Saratoga, Campbell, Sunnyvale, Los Altos, and Mountain View to the technology and professional service industries in Santa Clara County.

Project Features

The US 101 portion will convert 36 miles on US 101 to express lanes and add a second express lane for the majority of the corridor from Dunne Avenue in Morgan Hill to the San Mateo County line. The second express lane will provide a two-lane facility within urbanized segments. The US 101 express lanes will connect with the SR 85 express lanes in San Jose and convert US 101/SR 85 HOV direct connectors in Mountain View to express lane connectors.

The SR 85 portion will convert approximately 24 miles of existing High Occupancy Vehicle (HOV or carpool) lanes to express lanes and will add a second  express lane between SR 87 and I-280 in the median.  The project will also convert the existing HOV direct connector in south San Jose from US 101 to SR 85 to an express lane connector.  

The SR 85 draft environmental document was circulated from December 30, 2013 to February 28, 2014. It is available on the Caltrans District 4 environmental documents web page, under Santa Clara. Two public meetings were held on January 14 and 16, 2014 in San Jose. The express lane access design that was advanced for evaluation in the environmental document is controlled access which includes a 2-foot-wide double white solid stripe.  Access points will accommodate traffic from I-280, SR 17, SR 87, SR 237, US 101, and potentially county expressways and other major arterials. See map in Image Gallery tab for preliminary access points. 

The US 101 Draft Initial Study/Environmental Assessment (IS/EA)  was circulated from January 12, 2015 to February 26, 2015. It is available on the Caltrans District 4 environmental documents web page, under Santa Clara. Three public meetings were held on January 22, 2015 in Mountain View, January 28, 2015 in Downtown San Jose and February 4, 2015 in South San Jose.

SR 85 Environmental Documents

Caltrans, as the owner and operator of State Route 85 (SR 85), has approved the project's final environmental document as an Initial Study with Negative Declaration/Environmental Assessment with Finding of No Significant Impact. The environmental document includes clearance of double-lane express lanes in each direction of SR 85 between I-280 and SR 87. The overall boundaries of the project cover SR 85 from the US 101 interchange in Mountain View to the US 101 interchange in south San Jose.
