85/101 North Interchange Project

Santa Clara, California
Owner: Santa Clara Valley Transportation Authority

Purpose

The intent of this project will be to eliminate traffic congestion in a high volume area. This will be accomplished by reconfiguring four major interchanges within a 1.3 mile stretch of U.S. 101. To achieve this goal, Graniterock will be constructing 5 bridges, creating 4 new signaled intersections in the city of Mountain View, and adding an HOV (high occupancy vehicle) interconnect between 101 and 85. This project began in December of 2002 and is expected to be completed in early 2006.
