Interstate 380 (abbreviated I-380) is a short spur highway that connects Interstate 280 in San Bruno, California to San Francisco International Airport in South San Francisco, California; the eastern terminus of I-380 is the junction with U.S. Route 101. The entire length of the highway is a short 3.3 miles (5.3 km).
The Highway is signed as the "Quentin L. Kopp Freeway", after a prominent State Senator from San Mateo County, California. The road was previously named the Portola Freeway, after Gaspar de Portolà.
There are plans to extend Interstate 380 all the way to CA-1 (Cabrillo Highway), but due to the route passing over the San Andreas Fault and community opposition, it appears unlikely that it will ever be extended. The westbound lanes of I-380 branch off to the right at I-280, leaving a very wide, paved space which would carry the freeway extension under I-280 towards CA-1. A pair of unused bridges crossing over the I-280 South to I-380 East offramp remain as evidence. Caltrans remains optimistic about this plan, as the exit numbers at I-280 do not go to zero.
