SAN BERNARDINO — Caltrans has started a project to improve safety and reduce traffic congestion on State Route 58 by closing the last gap in a continuous four-lane expressway from U.S. 101 in San Luis Obispo County to State Route 14 and Interstate 40 in Barstow.
"State Route 58 is a vital agriculture link that connects the Central Valley to the rest of the nation. This project will break the bottleneck, increase safety, and expedite the delivery of half of our nation's produce, by separating slow-moving vehicles from passenger cars."
The SR-58 Kramer Junction Expressway project will realign the roadway, construct new pavement, widen the median, build a new interchange at US 395, and separate the railroad crossing from the roadway to accommodate the increased volumes of oversized vehicles.
For this project, Caltrans is using the Construction Manager – General Contractor project delivery method, where the contractor works with the designers to build the project quickly and efficiently. The estimated $191 million project was awarded to Kiewit Infrastructure West Cooperation and is scheduled to open to traffic in 2021.
Caltrans is working in cooperation with California Highway Patrol, Federal Highway Administration, San Bernardino County Transportation Authority, US Fish & Wildlife Service, California Department of Fish & Game, San Bernardino County, Bureau of Land Management, Edwards Air Force Base, Burlington Northern Santa Fe Railway, and the Community of Kramer Junction.
