ConDig (17-Nov–22)  Civil contractor and construction materials producer Granite Construction has secured a $170 million contract to revamp Interstate 10 (I-10) near Tucson, Arizona. 

Under the deal with the Arizona Department of Transportation (ADOT), the project will involve the construction of six new bridges, drainage facilities, mechanically stabilized earth walls and electrical improvements. 

Granite will supply over 91,500 tons of hot mix asphaltic concrete and 67,500 tons aggregate base materials from its Tangerine Road facility. 

The project is slated to kick off in January next year and be completed by October 2025.

“This project combines two separate projects, ADOT’s I-10 widening and Pima County’s Sunset Road extension, into a single project that will complete one of the last remaining I-10 segments to be widened/improved in Tucson,” said Todd Hill, vice president of regional operations for Granite. 

“During construction, traffic impacts will be minimized by shifting traffic to the existing frontage roads, allowing expedited construction of the segment.”

Granite added that the project is aimed at improving I-10 between the Ina Road and Ruthrauff Road interchanges by reconstructing it to provide four general purpose lanes in each direction.

In July, Granite snagged a $55 million road upgrade deal in Wasilla, Alaska.
