The Harbor Freeway is one of the principal north-south freeways in Los Angeles County, California. It runs from Gaffey Street in San Pedro to the Four Level Interchange north of downtown Los Angeles, where it intersects with the Hollywood Freeway and narrows into the Pasadena Freeway. Between the Four Level Interchange and the Santa Monica Freeway, it is signed as California State Highway 110; it is signed as Interstate 110 for the rest of its length.

The Harbor Freeway is, with the Long Beach Freeway, the principal means for freight to get from the port of Los Angeles to rail yards and warehouses further inland. Its interchange with the Santa Monica Freeway is notoriously busy and congested, and the portions bordering Bunker Hill in northwest downtown Los Angeles are choked with traffic at peak travel times.

The I-110 number was once used for the stub of the San Bernardino Freeway (mostly I-10) west of I-5.

Notable Features

The Harbor Freeway is noted for its elaborate high-occupancy vehicle lane infrastructure, with HOV lanes elevated above the rest of traffic in many areas and with towering and graceful on- and offramps. Of particular note is the 7-story ramp that connects the eastbound Century Freeway to its northbound carpool lanes, offering splendid views of virtually the entire Los Angeles Basin and the San Gabriel Mountains on (infrequent) clear days.

Pop Culture References

A portion of the Harbor Freeway is shown on the cover of punk rock legends The Minutemen's double-album, Double Nickels on the Dime; the sign shown for San Pedro (the band's hometown) uses the old designation of California State Highway 11 .
