State Route 84 is a split-section California State Highway consisting of two sections. The first section is an east-west arterial road running from San Gregorio to Menlo Park, across the Dumbarton Bridge through Fremont and Newark and ending at I-580 in Livermore. The route overlaps the freeway segment of U.S. 101 between Woodside Road in Redwood City and Marsh Road in Menlo Park. The segment between Marsh Road and the Dumbarton Bridge has been upgraded to an expressway and is known as the Bayfront Expressway. The segment from the western end of the Dumbarton Bridge to the interchange with I-880 has been upgraded to a freeway.

The other section is a north-west arterial road that begins at Route 12 in Rio Vista, passes through Ryer Island (where it connects to Route 220), and ends at the Interstate 80 interchange in West Sacramento. However, plans are underway to turn maintenance of SR 84 through West Sacramento to that city.

A ferry provides the crossing over Cache Slough from Rio Vista to Ryer Island. The ferry, a diesel-powered boat operated by Caltrans, is in operation twenty-four hours per day and charges no toll.

Route 84 is legally defined to continue from I-580 to Route 4 in Antioch, but there are currently no plans in place to bridge the gap at this time. A plan to build a $600 million toll road called the Mid-State Tollway along the proposed route was suspended in 2001 due to local opposition.

This route is part of the California Freeway and Expressway System [http://www.leginfo.ca.gov/cgi-bin/displaycode?section=shc&group=00001-01000&file=250-257 CA Codes (shc:250-257)] ] and is eligible for the State Scenic Highway System [http://www.leginfo.ca.gov/cgi-bin/displaycode?section=shc&group=00001-01000&file=260-284 CA Codes (shc:260-284)] ] .
