In 1988, Bay Area voters approved Regional Measure 1, raising tolls on the state-owned bridges to a uniform $1 and pledging the proceeds to specific bridge corridor improvements. Caltrans owns and operates the toll bridges and is responsible for the construction of the voter-approved RM 1 projects, including a new span for the Benicia-Martinez Bridge, a replacement for the west span of the Carquinez Bridge, and widening the San Mateo-Hayward Bridge. BATA is responsible for funding and overseeing the RM 1 bridge program.
Regional Measure 2
With transbay travel in the Bay Area expected to increase by approximately 40 percent over the next two decades, the California Legislature in 2002 determined that new investment in the bridge corridors was needed, along with a new revenue source. Regional Measure 2, which was approved by Bay Area voters in March 2004, increased tolls on the region's state-owned bridges by $1 and funds a balanced set of transportation projects in the bridge corridors, including new mass transit options and critical highway bottleneck improvements, including the Dumbarton Express. The project list also included funding for the Transbay Transit Center, seismic improvements and extensions for BART, Muni Metro's T Third Street, AC Transit bus service upgrades, and more. The list of projects — called the “Regional Traffic Relief Plan” and included in the enabling legislation — will be financed by the $1 increase in tolls. MTC will be responsible for allocating the toll. BATA will be responsible for issuing bonds and for submitting updates on the Regional Traffic Relief Plan to the state Legislature.
Regional Measure 3
In 2017, the California Senate passed SB 595 to put Regional Measure 3 on the ballot in the nine Bay Area counties. The expenditure plan for the project would allocate $4.45 billion to various transportation projects including funding for the San Francisco Downtown Rail Extension, fleet expansions for Muni Metro and BART, ferry service expansion, various road projects, and Sonoma–Marin Area Rail Transit expansion. RM3 was on the ballot in the June 2018 election in the nine counties and required a majority vote to pass. As of June 13, 2018, 55% of the votes in the counties were in favor, ensuring that the measure would pass once the votes are certified in July 2018. A lawsuit challenging the legal status of the toll increase was filed but ultimately failed in April 2019, allowing the release of funds from the toll.
Toll Bridge Seismic Retrofit Program
Since 1998, drivers on all Bay Area state-owned bridges have paid a $1 seismic surcharge to help finance a seismic retrofit program to strengthen and reinforce bridge structures and roadways on five of the bridges in the event of a major earthquake. On January 1, 2007 the seismic surcharge increased to $2 per vehicle, and then increased to $3 on July 1, 2010.
