Interstate 5 (I-5) is a major north–south route of the Interstate Highway System in the United States, running largely parallel to the Pacific Coast between the Mexican border and the Canadian border. The segment of I-5 in California runs across the length of the state from the Mexican border at the San Ysidro Port of Entry in the San Ysidro neighborhood of San Diego to the Oregon state line south of the Medford-Ashland metropolitan area. It is the longest interstate in California at 796.77 miles (1,282.28 km),[1] and accounts for more than half of I-5's total length of 1,381.29 miles (2,222.97 km).[2] It is also the second longest stretch of Interstate Highway (and the longest for a north-south Interstate) with a single designation within a single state after I-10 in Texas.
It is the more important and most-used of the two major north–south routes on the Pacific Coast, the other being U.S. Route 101 (US 101), which is primarily coastal. I-5 links the major California cities of San Diego, Santa Ana, Los Angeles, Stockton, Sacramento, and Redding. The San Francisco Bay Area is about 80 miles (130 km) west of the highway.
I-5 is known colloquially as "the 5" to Southern California residents and "5" to Northern California residents due to varieties in California English. I-5 also has several named portions: the John J. Montgomery Freeway, San Diego Freeway, Santa Ana Freeway, Golden State Freeway, and West Side Freeway.[3]
