Granite wins contract for four-lane widening project in California


US-based infrastructure company Granite has been awarded a $20m contract by the California Department of Transportation (Caltrans) for the State Route 46 4-Lane Widening Project in Lost Hills.

The contract will be included by the company in its record for Q1 2021.

In this project, the State Route 46 will be widened from a two-lane highway to four lane between post miles 29.7 and 31.9 in Kern County.

The project includes construction of two new lanes, a bridge over the California Aqueduct, a crosswalk beacon at the State Route 46/Bruning Avenue intersection.

Scope of the project also includes construction of a large drainage basin on the west side of Lost Hills Road, curb, gutter, and crosswalks throughout the town of Lost Hills.

Granite area manager Darryl Ebel said: “We have a 45-year history of working with Caltrans District 6 to improve safety and mobility for the traveling public in California’s Central Valley. What makes this project unique is our construction of a new bridge over the California Aqueduct.

“Working over the aqueduct requires heightened awareness, planning, and execution to prevent environmental impacts. Granite’s environmental professionals will provide integrated project support by helping to plan operations and protect this critical water conveyance resource during all phases of the project.”

Granite claimed this will be the first project to use construction materials drawn from its new Solari facility in Bakersfield, California.

The construction materials for the project will include 117,000 tonnes of aggregate base, 35,000 tonnes of hot mix asphalt, and 15,000 tonnes of rubberised asphalt concrete.

Construction of the project is expected to begin in March this year and is likely to conclude in June next year.
