Granite secures two contracts for Interstate 5 rehabilitation in California


Infrastructure company Granite has been awarded two contracts worth $38m to take up works on Interstate 5 (I-5) near Three Rocks, California.

Under the first contract, worth over $27m, the company will rehabilitate pavement and work on culvert improvements on I-5. The second contract is valued at over $11m and includes replacement of two bridge structures over Tumey Gulch.

The works, likely to start in July 2022, is scheduled to be completed in October 2023.

Granite is likely to include the contracts in its second quarter Corporate Action Plan (CAP).

Granite regional operations vice president Carter Rohrbough said, “The I-5 Rehabilitation project is a great opportunity to showcase our expertise in transportation infrastructure.

“We are executing the Tumey Gulch bridge replacement project as an internal partnership between our Valley Region and Central California Region, allowing us to pull experience from across the company.”

“In addition, our Coalinga facility will be providing the materials to both projects, so these jobs are strongly aligned to Granite’s new home market strategy,” he added.

Under the first contract, the company will rehabilitate 10.6 miles of pavement with Hot Mix Asphalt (HMA) and Rubberised Hot Mix Asphalt (RHMA).

Four new drainage systems and two box culverts are other works to be taken up. As many as 97 culverts will be lined with cured-in-place pipeliner (CIPP).

As part of the second contract, the company will be responsible for replacing bridge structures for north and south-bound lanes. The new ones will be single span structures with precast girders and cast-in-place concrete decks.

One mile of I-5 will undergo reconstruction to match the new bridge deck elevations.

Granite’s Coalinga Quarry and Hot Plant will supply the required materials for the projects that include 103,000 tonnes of HMA, 56,000 of RHMA, and 10,000 cubic yards of import borrow.
