ORANGE COUNTY, CA — Jacobs has been selected by the Orange County Transportation Authority to provide construction management services for two major highway improvement projects designed to enhance mobility and reduce congestion in Orange County, California.
The SR-91 Improvement Project between La Palma and SR-55 will add a new eastbound general-purpose lane, widen bridges, and reconstruct interchanges to improve traffic operations. SR‑91 carries more than 300,000 vehicles per day and is a critical connection between Orange County and the Inland Empire, where growing demand has increased congestion and delays.
Jacobs will also deliver construction management services for the I-5 Improvement Project between I-405 and Yale Avenue. This section of I-5 is one of the busiest in Southern California, with average daily traffic exceeding 275,000 vehicles. The project will enhance safety, improve travel times, and support economic growth in the region.
“These projects are essential to improving mobility in one of the nation’s most congested regions," Jacobs Executive Vice President Eva Wood said. "Los Angeles and Orange County drivers lose an average of 88 hours annually to traffic delays, and with population and employment expected to grow by more than 20 percent combined by 2045, the need for efficient, resilient infrastructure has never been greater.”
Improvements to SR‑91 and I‑5 will support Orange County’s long‑range transportation plan, delivering measurable benefits for commuters, residents, and visitors through congestion relief, increased reliability, and modernized infrastructure.
