New Benicia-Martinez Bridge
Project Sponsor:
Caltrans
Project Description:
The existing Benicia-Martinez Bridge provides Interstate 680 access across
the Carquinez Strait between Contra Costa and Solano counties. A new span
that will carry five lanes of northbound traffic is being built just east
of and parallel to the existing span. The latter will be converted to carry
four lanes of southbound traffic as well as a new bicycle and pedestrian
pathway. As part of this project, a new 9 lane toll plaza with one carpool
bypass and two FasTrak® open road tolling express lanes will be constructed in Contra
Costa County.
