Granite Construction recently announced it secured a contract of about $24 million to replace 10 aging bridges along Route 66 in Amboy, California.
Funding from San Bernardino County comes from state and federal sources.
This project addresses structures that no longer meet modern load-bearing standards and are unable to support today’s vehicular traffic volumes and weights safely.
Construction is expected to begin in December and be completed in April 2027, the company’s news release stated.
The release didn’t state how many bridges on Route 66 would be replaced. A spokesman speaking on behalf of Granite said it would be 10.
The targeted stretch of Route 66 serves as a vital link between 29 Palms and Las Vegas, providing essential access to the Mojave National Preserve.
“By upgrading these bridges, Granite will enhance safety, reliability and long-term resilience for both travelers and visitors along this iconic route,” the company stated.
“Granite has a long history of improving infrastructure in the High Desert,” said Bill Moore, Granite’s vice president of regional operations. “This project not only strengthens a key transportation corridor but also reinforces our dedication to the communities we serve.”
Flash flooding about 10 years ago destroyed or damaged dozens of Route 66 bridges in the region. San Bernardino County has been slowly replacing them; it maintains a website to detail its progress here.
