Drivers will receive a major upgrade to their commute as a $298 million project to rehabilitate the 605 Freeway is set to begin.

The construction will span nearly 200 “lane miles” of the freeway beginning from the San Gabriel Valley all the way down to Long Beach, according to Caltrans.

Funds for the major project include:
-$273 million from the federal Infrastructure Investment and Jobs Act (IIJA)
-$23 million from S.B. 1 also known as the Road Repair and Accountability Act of 2017

Construction and rehab efforts will extend the pavement’s lifetime up to 40 years, officials said. Other benefits include reducing costly repairs, providing a smoother ride for motorists and creating a safer environment for Caltrans workers by reducing the frequency and duration of pavement maintenance.

The following projects along the 605 corridor will repair or create new pavement and upgrade infrastructure between Los Alamitos/Long Beach and Duarte:

Officials said while most of the work on these projects will take place at night, drivers may encounter occasional daytime and weekend road closures. Caltrans will provide updates to any project schedules affecting travel in advance online.

“I-605 is a major artery for residents of the Gateway cities and the San Gabriel Valley and is a vital resource for commuters and the movement of goods throughout Southern California,” said District 7 Director Gloria Roberts. “Made possible by federal funding and continued support from SB 1, these projects will also lengthen the service life of this key thoroughfare.”

“Caltrans is aggressively upgrading and rebuilding our infrastructure in California, including pavement rehabilitation on major interstate routes that transport goods and connect local communities,” said Caltrans Director Tony Tavares. “The department and our federal partners are making a significant investment to rebuild and maintain our state highway system and provide users with a best-in-class experience.”
