The California Department of Transportation (Caltrans) has appointed Granite Construction as the construction manager / general contractor (CM/GC) for the $257m State Route 99 rehabilitation project in the US.

The rehabilitation project will cover a road stretch from El Dorado Street to Clinton Avenue in Fresno, California.

By the end of this year, Granite will assume the construction management portion of the contract, and from mid-2024 it will assume the role of general contractor.

Granite regional vice-president Carter Rohrbough said: “We are honoured to once again team up with Caltrans and improve transportation in Fresno.

“Being invited to be a part of the design and planning of this project provides Granite the opportunity to bring more value to Caltrans to ultimately support our communities and their traffic needs.”

Initially, Granite will be involved in the project construction management works, which are valued at $3m.

The rehabilitation works from El Dorado Street to Clinton Avenue will see the reconstruction of a 3.2-mile-long road stretch with concrete pavement. The work will also ease traffic congestion in Downtown Fresno with new improved interchange configurations.

New auxiliary lanes will be added and the road shoulder widths will be increased.

The scope of the $257m State Route 99 rehabilitation project includes the replacement or widening of six bridges, as well as several retaining and sound walls.

Granite will ensure that the drainage facilities within the project are replaced, which includes two pumping plants.

In April 2017, California Department of Transportation awarded a $22m contract to Granite Construction for the reconstruction of State Route 14 in Indian Wells.

Under the deal, Granite was responsible for the reconstruction of four miles of two-lane conventional highway, expanding it to four lanes.

The reconstructed expressway provides access to the Eastern Sierra Mountain range, which features Mammoth Mountain Resort.
