The Benicia-Martinez Bridge has provided Interstate 680 the crossing of the Carquinez Strait between Contra Costa and Solano counties since 1962. The new Benicia-Martinez Bridge Project include the following features:
The purpose and needs for the new bridge are as follows:
A "value engineering analysis" found that a redesign of the I-680/I780 interchange could result in an estimated net project cost savings of $11 million. The California Department of Transportation (Caltrans) and the Bay Area Toll Authority (BATA) sought and received concurrence for the redesign from the affected jurisdictions - the Contra Costa Transportation Authority, the Solano Transportation Authority and the City of Benicia. The redesign was approved by the Federal Highway Administration (FHWA), and was honored by FHWA with its 1997-98 "Most Outstanding Value engineering" award.
In November 1988, voters in the nine Bay Area counties passed Regional Measure 1 (RM 1) increasing the bridge tolls to $1.00 to fund improvements to the Bay Area Bridges and their approaches. Caltrans owns and operates the toll bridges, and is responsible for the design, construction and maintenance of the State owned toll bridges. The Contra Costa Transportation Authority, the Solano Transportation Authority, and the Cities of Benicia and Martinez worked closely to reach consensus on the design features of the new Benicia-Martinez Bridge Project. The Metropolitan Transportation Commission (MTC) is responsible for transportation planning, funding and agency coordination in the nine Bay Area counties. In 1998, MTC formed BATA, to assume the administration of the RM 1 tolls from the California Transportation Commission. BATA is responsible for project oversight of the RM 1 bridge program.
Schedule & Cost
The new bridge was completed in August of 2007. The total cost is expected to be $1.057 billion.
