California Code, Streets and Highways Code - SHC § 380.3

There will be increased motor vehicle traffic on San Pablo Avenue in the County of Contra Costa and the Cities of El Cerrito, Richmond, San Pablo, Pinole, and Hercules because traffic will be detoured onto San Pablo Avenue during construction work on State Route 80 to convert the existing shoulder to additional traffic lanes. Because of the increased traffic caused by the detour, the department may pay annually to that county and each of those cities the added costs of maintenance and operation of San Pablo Avenue.

This section shall remain in effect only until the department certifies to the Secretary of State that construction is complete on the project on State Route 80 in Contra Costa County to convert the existing shoulder to additional traffic lanes, and as of the date of that certification is repealed.
