Granite wins contract for Cosumnes Bridge Replacement Project in the US


Sacramento-headquartered California Department of Transportation (Caltrans) has awarded the Cosumnes Bridge Parent Package to US-based infrastructure company Granite as part of the $48m Construction Manager/General Contractor (CMGC) contract for the Cosumnes Bridge Replacement Project in California.

Located on State Route (SR) 99, in Elk Grove, California, the Project has been developed in seven phases to allow construction to continue while the design on other improvements is being finalised.

The CMGC contract is said to be the final of the seven contracts of the overall $167m Cosumnes Bridge Replacement Project.

Granite said that dividing the project allows for speedy delivery, which is estimated to be two years ahead of the owner’s anticipated timeline.

The project involves removing and replacing four bridges over the Cosumnes River in addition to replacing two existing railroad overhead and underpass bridges with a single new overhead bridge, which requires partial realignment of the SR-99 southbound.

The scope of work under the contract involves laying out 3.7km of freeway to connect the newly constructed bridges, along with roadway excavation, deck and barrier improvements at Dillard Road Overcrossing and construction of the Eschinger Road/SR-99 interchange.

It also includes ramp metering installation and intelligent transportation system, besides removing the existing McConnell Underpass and overhead bridges at the Union Pacific Railroad tracks.

Granite has planned to commence construction on the Parent Package immediately and the Project is set to be completed by 2024.

Granite project manager George Delano said: “Being selected for this final package allows us to take the project across the finish line with this first-rate Caltrans team.

“We are proud to be part of this collaborative CM/GC team made up of Caltrans, Granite, our subcontractors, and third-party stakeholders which has overcome numerous challenges to deliver exceptional results, and will continue to work together to improve safety for the traveling public.”
