Interstate 215 (I-215) is a unique auxiliary interstate with two distinct segments—one in Southern California and another in Utah—each serving different metropolitan regions. Despite sharing the same designation, the two I-215s are entirely separate routes, both functioning as major bypasses and commuter corridors.
In California, I-215 runs for approximately 54 miles through San Bernardino and Riverside Counties, connecting with I-15 at both ends. This loop serves as a vital artery for the Inland Empire, easing congestion on I-15 and providing access to cities like San Bernardino, Riverside, and Moreno Valley. Major junctions include I-10, SR-60, and SR-91, making I-215 a critical part of Southern California’s freeway grid.
In Utah, I-215 forms a 28-mile beltway around Salt Lake City. This loop intersects with I-15 twice and provides access to several suburbs including Murray, Taylorsville, Holladay, and North Salt Lake. It also connects to I-80, making it an essential route for both local and through traffic. The Utah segment is especially important for ski resort access and east-west travel across the Wasatch Front.
