INTERSTATE 110 (CALIFORNIA)

'Interstate 110' (abbreviated 'I-110') is one of the principal north-south interstate freeways in Los Angeles County, California. As the 'Harbor Freeway', it connects San Pedro in the Harbor Area to Downtown Los Angeles.
Although Interstate 110 ends at its parent route, Interstate 10 (the Santa Monica Freeway), the Harbor Freeway legally continues as California State Route 110 to the Four Level Interchange, where it then becomes the Pasadena Freeway.

Route description

The Harbor Freeway begins at Gaffey Street in San Pedro, where it then travels mostly due north to the Santa Monica Freeway (Interstate 10) at a point south of downtown Los Angeles, where it becomes signed as California State Highway 110. I-110 is primarily within the city limits of Los Angeles, running through the Harbor Gateway, a two-mile wide north-south corridor that was annexed by the city of Los Angeles specifically to connect San Pedro, Wilmington and the Port of Los Angeles with the rest the city.
In addition, the Harbor Transitway, a grade-separated bus and high-occupancy vehicle corridor in the median of the 110, runs between State Route 91 (Gardena Freeway) and the south side of Downtown Los Angeles.
The Harbor Freeway, along with the Long Beach Freeway, are 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.

History

The Harbor Freeway (south of Santa Monica Freeway) was built from early 1950s to the 1960s. The I-110 number was also once used at the Four Level Interchange for the stub of the San Bernardino Freeway between the US-101 and the I-5 from 1963 until 1968 which is currently signed as I-10 or unsigned CA-10. Originally the highway was signed as U.S. Route 6 which was decommissioned and renamed California State Route 11 in 1964.^[3] In December 1978, the Harbor Freeway was approved as an Interstate Highways by FHWA. In 1981, the CA-11 designation was recommissioned as Interstate 110 on Harbor Freeway, and California 110 on Pasadena Freeway ^[4].

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. Of particular note is the 7-story ramp that connects the eastbound Century Freeway to its northbound carpool lanes, offering splendid views of the entire Los Angeles Basin and the San Gabriel Mountains, weather permitting.
