Business Loop I-15 - Lake Elsinore

Business Loop I-15

Business Loop I-15 through Lake Elsinore follows portions of old U.S. Highway 395 and California State Route 71 west from Interstate 15. Separating from the freeway at Exit 73, the route takes Diamond Drive south to connect with Lakeshore Drive west to Short Street north. Main Street leads the business loop north through the city street grid back to I-15 at Exit 75. A signed western spur of the route extends along Graham Avenue and Lakeshore Drive to SR 74 (Riverside Drive) as well.

The 1991 California State Highway System Log references three branches along Business Loop I-15 in Lake Elsinore. The center leg links Interstate 15 with Graham Avenue along a 0.7 mile long section of Main Street. The northern segment spurs 2.5 miles northwest along Graham Avenue to SR 74 (Riverside Drive). The eastern section loops 2.2 miles along a combination of S Main Street, Short Street, Lakeshore Drive and Railroad Canyon Road east from the city center to Interstate 15.
