Interstate 380 (abbreviated I-380) is a short 3.3-mile (5.3 km) spur interstate highway connecting Interstate 280 in San Bruno, California to U.S. Route 101 near the San Francisco International Airport (SFO). The highway primarily consists of only three intersections: I-280, El Camino Real (State Route 82), and U.S. 101. However, I-380 never connects to Interstate 80, its parent interstate.
I-380 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 Gaspar de Portolà.

[edit] Future
| This article contains information about a planned or expected future road. It may contain information of a speculative nature and the content may change as the road's construction or completion approaches and more information becomes available. |
There are plans to extend I-380 all the way to State Route 1 (Cabrillo Highway), but due to the route passing over the San Andreas Fault and community opposition, it appears that is is currently an open question to whether that will ever be extended or not. 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 SR 1. This space is currently often used as storage space for equipment used in highway maintenance. A pair of unused bridges crossing over the I-280 South to I-380 East offramp remain as evidence.
Despite the opposition, Chapter 2, Article 3, Section 608 of the California Streets and Highways Code still legally defines Route 380 as traveling from "Route 1 near Pacifica to Route 280 in San Bruno",[1] and the exit numbers assigned at I-280 go to five instead of one or zero.[2]
Although recent California Highway Log still propose alternative plans to extend by more peculiar shape, slightly southwest of the I-280/I-380 interchange might make the extension project slightly longer perhaps making the I-380 a bent V-shape. This project is very controversial, and unlikely to come true.
