Project Description:
The Bayfront Expressway (State Route 84) in San Mateo County serves the western approach to the Dumbarton Bridge from U.S. 101. The original roadway was a four-lane facility with no shoulders. The expressway has been widened to six lanes, three in each direction, with full standard shoulders and lane widths.
