US-based  construction company Granite has received a contract worth approximately $46m from the California Department of Transportation (Caltrans) for improving safety and mobility along US Highway 101 in Humboldt County.

The project will be funded by the Federal Highway Administration (FHWA).

Granite has added the contract value into its Q4 2022 CAP.

The project involves removing a T-intersection along the primary route between Arcata and Eureka, and building a new Indianola Interchange on the highway.

Besides a column-stabilised embankment with more than 5,000 columns averaging 65ft deep, the project will include 42,000 yd3 of cement-treated load transfer platform, and 24,000 yd3 of lightweight foam fill to support the roadway.

Granite vice president for regional operations Brent Fogg said: “This project includes several unique construction features to address challenging subsurface conditions and completion will result in safer passage along this stretch of highway.
