A description of Interstate 15
Interstate 15 (I-15) is a major transcontinental north/south route for movement of people and freight. The corridor is the main stretches from the City of San Diego (District 11) at its junction with Interstate 5, through the Los Angeles Metropolitan Area and the High Desert (District 8), Las Vegas, Rocky Mountain States, the states of the Midwest to the Canadian Border where it becomes Alberta Provincial Highway 4 (1,433 miles). California’s portion of the I-15 Corridor is 294 miles. The I-15 Corridor is vital to California and Nevada as a “gateway” for the movement of people and freight. It is a critical link between manufacturing industries and the international ports of Southern California.
In District 11, I-15 links major urbanized areas, high growth areas and smaller communities, recreational areas, major freight facilities, and warehousing and distribution centers. I-15 serves as an interregional route for travel and goods movement by linking the San Diego metropolitan area with Mexico to the south, and the Riverside/San Bernardino area to the north, continuing in a northeasterly direction to Las Vegas. I-15 serves regional travel needs by serving the Cities of San Diego, San Marcos, Poway, Escondido, and the unincorporated communities of Bonsall, Fallbrook and Rainbow. I-15 is a heavily utilized commuter route providing access to the growing residential communities of Tierrasanta, Mira Mesa, Scripps Ranch, Rancho Penasquitos, Sabre Springs, Carmel Mountain Ranch, Poway, Escondido, and Rancho Bernardo. The I-15 Corridor is the direct travel route for tourists traveling to various mountain resorts and Las Vegas. It is used by travelers destined the Mojave Desert, Death Valley, the Eastern Sierra Nevada Mountain Range, and the Colorado River.
