About the Project

Relief is on the way for the more than one million drivers traveling through the Devore Interchange in San Bernardino County each week. As one of three routes in and out of Southern California, the Interstate 15 (I-15) and Interstate 215 (I-215) interchange is a heavy goods movement corridor and recreational gateway to places like Las Vegas and the Colorado River in addition to being a commuting route.

As a result, the Devore Interchange, of which I-15 has been designated a Corridor of National Significance, has become one of the worst grade-related bottlenecks in the nation with traffic queues backing up as far as five miles.

Recognizing the need for improvement, the California Department of Transportation (Caltrans) and San Bernardino Associated Governments (SANBAG) worked together to develop the Devore Interchange Project. It marks the first Caltrans Design-Build project in the Inland Empire and will improve mobility and maximize operations through the corridor.
