HNTB awarded prime consultant contract for Last Chance Grade Project in Del Norte County, California

Project to focus on a balanced permanent solution to slope instability and roadway failure

OAKLAND, Calif. (March 6, 2020) The California Department of Transportation selected infrastructure solutions firm HNTB Corporation to lead the Project Approval and Environmental Document phase of the Last Chance Grade project.

For decades, a 3-mile stretch of Highway 101 between Klamath and Crescent City, California, has experienced road closures, delays and costly maintenance repairs due to landslides and other impairments. Located along the Pacific Ocean within the Redwood National and State Parks also a United Nations Educational, Scientific and Cultural Organization World Heritage Site – this project requires a solution that balances geotechnical and geological complexity and environmental sensitivity.

“We are thrilled at the opportunity to work hand-in-hand with Caltrans and project stakeholders to identify a safe, smart and sustainable permanent solution for the Last Chance Grade,” said Dina Potter, HNTB vice president and project manager. “We have assembled a team that includes North Coast residents familiar with the local conditions and community, and industry-recognized experts with the proven ability to deliver big, complicated projects like this around the country.”

HNTB will define, develop and environmentally clear a solution that meets Caltrans and regulatory agency approval and addresses the needs of project stakeholders and North Coast communities. Depending on the alignment, preliminary construction values range from $350 million to $1 billion. Throughout the multi-year contract, HNTB will manage and collaborate with a large, multidisciplinary team of more than 30 consulting firms and vendors, including expertise and task leadership from ICF, Kleinfelder, Inc., MIG, Inc., SHN Consulting, and WRECO.

“I appreciate the care and attention HNTB took in assembling this high-caliber, diverse and experienced team,” said Caltrans District 1 project manager Jaime Matteoli. “I am looking forward to working with the HNTB team.”

HNTB has led a number of similarly complex efforts in collaboration with Caltrans in recent years, including the Presidio Parkway/Doyle Drive Replacement in San Francisco and the Tom Lantos Devil’s Slide Tunnel in San Mateo County, among others.
