I-110

About I-110

Also known as Harbor Freeway.

Interstate 110 is a three-digit auxiliary route of Interstate 10, with an odd prefix digit that designates it a spur rather than a loop. The number appears in two states. The best known instance is in Los Angeles, California, where the signed Interstate 110 is the Harbor Freeway running north from the harbor area toward downtown Los Angeles. South of Interstate 10 the route is numbered Interstate 110, and north of that point it continues as State Route 110, the Pasadena Freeway, into Pasadena.

The California Harbor Freeway serves as a major commuter corridor through South Los Angeles and as a commercial route connecting downtown with the ports of Los Angeles and Long Beach. It carries heavy traffic and includes express toll lanes along part of its length.

The other Interstate 110 is in El Paso, Texas, where it is a very short spur of well under a mile that connects Interstate 10 with the Bridge of the Americas, an international crossing over the Rio Grande into Ciudad Juarez, Mexico. The Texas route is almost entirely unsigned and is the shortest Interstate in that state.

History

The Harbor Freeway in Los Angeles was built in the 1950s and opened in stages into the early 1960s, originally carrying state route numbers before the Interstate 110 designation was applied along the harbor segment in 1981. The El Paso route was designated in the 1960s to provide a direct Interstate connection from Interstate 10 to the Bridge of the Americas border crossing.
