Granite awarded $63M contract for Cosumnes Bridge Replacement Project in California

Granite was awarded the Child Project 6 portion of the contract, which is included in a phased seven-part delivery of the overall $167 million project.


Watsonville, California-based Granite Construction Co. has announced it was awarded the Child Project 6 (CP6) portion of the Construction Manager/General Contractor (CM/GC) contract for the Cosumnes Bridge Replacement Project in Sacramento County, California.

This CM/GC contract is part of a phased seven-part delivery of the overall $167 million project. The $63 million project contract is included in Granite’s third quarter 2020 backlog.

The project, which is being overseen by the California Department of Transportation (Caltrans), includes the removal and replacement of four bridges over the Cosumnes River, as well as replacing two existing railroads overhead and underpass bridges with a single new overhead bridge, requiring partial realignment of State Route (SR) 99 southbound in Elk Grove.

CP6 is a segment of the overall project which has been subdivided into seven contracts to allow construction to proceed while design is being completed on other improvements. The segmentation of the project allows for an accelerated delivery, which is currently one year ahead of the owner’s anticipated timeline. The scope of CP6, Granite’s sixth awarded contract for this project, includes the removal and replacement of the two existing Cosumnes River bridges over the main river and overflow sections.

“The Granite team continues to work alongside the Caltrans design and field teams with the shared focus on achieving the project goals,” said Granite Regional Vice President Carter Rohrbough. “We look forward to our continued collaboration with Caltrans on the successful and safe completion of this critical infrastructure.”

Construction materials for the project will be supplied by Granite’s Bradshaw Facility. Construction is expected to begin in July and conclude in October 2022.
