Flatiron Featured Project – Carquinez Bridge Project (04-013014)

FCI decided to use PMIV on their over $ 245 Million 04-013014 project.

The scope is as follows:

Project construction limits are along I-80 from Cummings Skyway in Contra Costa County to SR 29 in Solano County. The project features of the replacement bridge and related amenities are:

  • Replacement bridge alignment west of existing bridges.
  • Provide for three mixed-flow plus one high occupancy vehicle (HOV) lane and a bicycle/pedestrian lane.
  • Suspension bridge type requires only two main piers.
  • New pedestrian/bicycle lane will be provided on replacement bridge; new visual access on both northern and southern shoreline.

The new Carquinez Suspension Bridge is the third bridge to be built at this site. It replaces the existing bridge, built in 1927, and carries traffic westbound on I_80. This new three span 3,465_foot_long structure is North America’s first suspension bridge of its kind to be built in 35 years. At bid time, it was the largest project ever awarded by the California Department of Transportation.

The superstructure utilizes a steel orthotropic deck section. The 24 deck sections (each 50 meters long) were transported on three oceangoing vessels from Japan and jacked into place directly from the ship using the bridge’s main suspension cables.

FCI decided to use PMIV on their project. Their existing data was transferred into PMIV database.
