The Arizona Department of Transportation has awarded a $34m contract to US-based construction firm Granite for a roadway rehabilitation project in Tucson.

The project will involve rehabilitating a nine-mile road stretch on the six-lane State Route 77/Oracle Road in Pima County, Arizona, which connects Interstate 10 (I-10) to the city of Tucson, Casa Adobes and the town of Oro Valley.

Granite will be responsible for milling and replacing the asphaltic concrete, constructing sidewalks and sidewalk ramps and repairing the bridge decks

It will also replace the guardrail and signals and lighting, extend the storm drain pipe and construct curbs and gutters, among other miscellaneous improvements.

Granite area manager Andrew Rogers said: “Granite is honoured to help revitalise Oracle Road, which is critical to the vitality of the Tucson metropolitan area.

“We build with sustainability in mind to ensure this infrastructure endures for the community for many years to come.”

Construction works will begin this month and are expected to be completed by March 2023.

Granite said that its Tangerine Road facility will supply 145,000t of asphaltic concrete and 20,000t of concrete aggregates required for the project.

In January, Granite secured a key contract worth around $48m for the Cosumnes Bridge Replacement Project in Sacramento County, California.

The California Department of Transportation (Caltrans) awarded the company the Cosumnes Bridge Parent Package of the construction manager/general contractor (CMGC) contract, the final award of a seven-part phased delivery of the $167m project.
