The California Department of Transportation has awarded an additional contract to the American River Constructors (ARC) joint venture (JV) team for the American River Bridge (ARB) Rehabilitation Construction Manager/General Contractor (CM/GC) project in Sacramento, California, US.

The ARC JV team includes infrastructure companies Granite and California Engineering Contractors.

The ARB, built in 1954, is a six-lane multispan bridge on the State Route 51 motorway.

The bridge deck will be replaced as part of this project, which aims to provide a multimodal link between East Sacramento and its downtown while protecting the piers and abutments from scour.

The scope of work comprises eliminating and installing the existing concrete deck and steel girder post-tensioning systems in one and two spans, along with shoulder expansion to accommodate construction traffic.

ARC will also build a class 1 bike lane alongside the bridge and link it to existing bike paths.

Since January 2021, a CM/GC Preconstruction Service contract has been in progress. It has recently concluded.

Three $70m child contracts have already been carried out for access, clearing, steel piling, and girder procurement, as well as bridge substructure development.

The most recent contract is a $131m parent project to build the superstructure for the three-stage replacement of the old bridge deck.

Granite has registered this contract in the second quarter (Q2) of this year’s committed and awarded projects.

Construction work is anticipated to be completed in Q1 2026.

Granite project executive George Delano said: “The ARB Project Team has done an amazing job of working together to deliver these child projects, including weathering the unprecedented storms from multiple atmospheric rivers last winter.

“We have hit the ground running on this final parent project and will have the girders erected before Thanksgiving [US holiday]. We look forward to a very successful project.”
