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 Richmond–San Rafael 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 Richmond–San Rafael 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 all-electronic tolling, citing that 80 percent of drivers are now using Fastrak and the change would improve traffic flow. On March 20, 2020, accelerated by the COVID-19 pandemic, all-electronic tolling was placed in effect for all seven state-owned toll bridges. The MTC then installed new systems at all seven bridges to make them permanently cashless by the start of 2021. In April 2022, the Bay Area Toll Authority announced plans to remove all remaining unused toll booths and create an open-road tolling system which functions at highway speeds. Improvements Seismic retrofit In the fall of 2001, the bridge commenced an extensive seismic retrofit program, similar to other bridges in the area. The retrofit was designed by a three-way joint venture between Gerwick/Sverdrup/DMJM under a design contract awarded in 1995. The retrofit is intended to allow the two-tier bridge to withstand a 7.4 magnitude earthquake on the Hayward Fault and an 8.3 magnitude quake on the San Andreas Fault. The foundation piers were strengthened by wrapping the lower section of structural steel in a concrete casing, installing new shear piles, and adding bracing to the structural steel towers. Isolation joints and bearings were also added to the main bridge structures (cantilever spans over the navigation channels) to strengthen the structure. The fifty-year-old bridge was showing its age and also needed age-related maintenance, which was performed in conjunction with the seismic upgrade work. There were reports of cars being damaged while traveling on the lower deck by fist-sized concrete chunks falling from the joints of upper deck slabs. A major part of the retrofit involved the long concrete causeway on the Marin side,
