I-80 Central Avenue Interchange Improvements Phase II
This project is the second in a two-phase effort to improve traffic congestion in the I-580/I-80/Central Avenue area. Phase I included signalization of intersections along the corridor and the installation of variable message signs (VMS) prohibiting left turns onto westbound I-80 from Central Ave during weekend peak periods. Phase II, the local roads realignment project, will improve traffic flow along Central Avenue by increasing the spacing between signalized intersections and reducing the backup of through traffic along Central Avenue by eliminating left turns onto Pierce Street. The traffic signal on Pierce Street will be removed and access at this intersection will be restricted to “right-in/right-out” so that no left turns will be allowed. Left turns into and out of Pierce Street will be accommodated by realigning San Mateo Street to connect with Pierce Street. San Mateo Street will be signalized and widened to provide adequate storage for left turns.
