Caltrans Marks the Completion of Two Inland Empire Freeway “Design-Build” Projects

(Victor Valley)– At a ribbon cutting ceremony today, Caltrans (District 8) celebrated the completion of two new projects and an innovative new approach to construction that is saving the state of California millions of dollars.

The recently completed Cajon Pass Rehabilitation and the Devore Interchange projects, located on Interstates 15 and 215 in San Bernardino, are the first two “design-build” projects in the Inland Empire. Design-build delivery, made possible by Senate Bill 4, is a method in which both the design and construction efforts are led by one source. As a result of this new approach, Cajon Pass was finished two years early, and Devore Interchange a year and a half early.

“The Inland Empire is a key part of the transportation system, not only for California, but the region and nation,” said Caltrans Director Malcolm Dougherty. “The successful delivery of these design-build projects means that it will continue to play this vital role, and can do so thanks to the innovative, cost-effective delivery made possible by design-build.”

The $121 million Cajon Pass corridor is a high-use route, with approximately 150,000 vehicles per day and no alternate routes in the regional vicinity. The project re-constructed 50 lane-miles of pavement focusing on the two outer lanes in both directions. What made this project unique was the constraint of not disturbing the area outside the freeway shoulders. This factor led the design-builder to use innovative strategies to maintain traffic control during construction activities.

The service life of the new pavement will be 40+ years, with minimal maintenance required.

The I-15/I-215 Devore Interchange is a major arterial for trucking, recreation and commuting. This interchange is a major goods movement gateway that serves the Los Angeles Basin and ports along the coast of Southern California. With 1,050,000 vehicles traveling weekly and 21,000 trucks passing through daily, the Devore Interchange was one of the worst grade-related bottlenecks in the United States.

Project benefits include the addition of truck bypass lanes to separate slow moving trucks from vehicles, the addition of one lane in each direction, safety improvements to reduce traffic weaving and increase operational standards, and the reconnection to the former U.S. Route 66 via Cajon Boulevard in Devore.

The total estimated cost of the Devore Interchange Project is $324 million. Of this, 24 percent is allocated by Measure I, San Bernardino County’s half-cent sales tax, 20 percent from federal funds and 56 percent from state funds.

Today’s ceremony was attended by Caltrans Director Dougherty, Federal Highway Deputy Director David Kim and State Assemblymember and Chairman of the Transportation Committee Jim Frazier.
