Historical toll rates

When the Benicia–Martinez Bridge opened in 1962, tolls were $0.25 per car. It was set to $0.35 in 1970, then increased to $0.40 in 1976. The basic toll (for automobiles) on the seven state-owned bridges, including the Benicia–Martinez Bridge, was raised to $1 by Regional Measure 1, approved by Bay Area voters in 1988. A $1 seismic retrofit surcharge was added in 1998 by the state legislature, originally for eight years, but since then extended to December 2037 (AB1171, October 2001). On March 2, 2004, voters approved Regional Measure 2, raising the toll by another dollar to a total of $3. An additional dollar was added to the toll starting January 1, 2007, to cover cost overruns concerning the replacement of the eastern span. The Metropolitan Transportation Commission, a regional transportation agency, in its capacity as the

Bay Area Toll Authority The Bay Area Toll Authority (BATA) is a state agency created by the California State Legislature in 1997 to administer the auto tolls on the San Francisco Bay Area's seven state-owned toll bridges. On January 1, 1998, the Metropolitan Transporta ...

, administers RM1 and RM2 funds, a significant portion of which are allocated to public transit capital improvements and operating subsidies in the transportation corridors served by the bridges. Caltrans administers the "second dollar" seismic surcharge, and receives some of the MTC-administered funds to perform other maintenance work on the bridges. The Bay Area Toll Authority is made up of appointed officials put in place by various city and county governments, and is not subject to direct voter oversight. Due to further funding shortages for seismic retrofit projects, the Bay Area Toll Authority again raised tolls on all seven of the state-owned bridges in July 2010. The toll rate for autos on the Benicia–Martinez Bridge was thus increased to $5. In June 2018, Bay Area voters approved Regional Measure 3 to further raise the tolls on all seven of the state-owned bridges to fund $4.5 billion worth of transportation improvements in the area. Under the passed measure, the toll rate for autos on the Benicia–Martinez Bridge will be increased to $6 on January 1, 2019; to $7 on January 1, 2022; and then to $8 on January 1, 2025. In September 2019, the MTC approved a $4 million plan to eliminate toll takers and convert all seven of the state-owned bridges to
