The bridge is part of State Route 84, and is directly connected to Interstate 880 by a freeway segment north of the Fremont end. There is no freeway connection between U.S. 101 and the southwest end of the Dumbarton Bridge. Motorists must traverse one of three at-grade routes to connect from the Bayshore Freeway to the bridge. These are (from northwest to southeast): the Bayfront Expressway, a limited-access road linking to U.S. 101 at Marsh Road, Atherton (the official routing of SR 84) Willow Road (SR 114), an approximately one-mile expressway through east Menlo Park to U.S. 101 University Avenue (SR 109), an arterial road and the main commercial street of East Palo Alto.
