Interstate 110 (I-110) and State Route 110 (SR 110) are two connected highways in Los Angeles County, California. They go between the Port of Los Angeles and Pasadena, going through Downtown Los Angeles. Between the Port of L.A. and Interstate 10, the road is called the Interstate 10. It is called California State Route 110 between Interstate 10 and Pasadena. The whole route is also called the Harbor Freeway. The route is about 32 miles (51 km) long.
Exits[change | change source]
Except when a letter is put before it, postmiles were measured on the road as it was in 1964, based on how it was at the time, and do not necessarily show the current mileage. R reflects a change in the route since then, M indicates a second change, L refers an overlap because of a correction or change, and T indicates postmiles that were temporary (for a full list of prefixes, see the list of postmile definitions). Segments that have not been built or are now controlled locally may be left out. The entire route is in Los Angeles County.
