State Route 91, also known as simply The 91, is a major east-west freeway located entirely within Southern California and serving several regions of the Greater Los Angeles metropolitan area. Specifically, it runs from Vermont Avenue in Gardena, just west of the junction with the Harbor Freeway (Interstate 110), east to Riverside at the junction with the Pomona (State Route 60 west of 91), Moreno Valley (State Route 60 east of the 91), and Escondido (I-215) freeways.

Route

From the Harbor Freeway to its intersection with the Long Beach Freeway in northern Long Beach, SR 91 is named the Gardena Freeway. Between the Long Beach Freeway and its intersection with the Santa Ana Freeway at the Fullerton-Anaheim border, it is named the Artesia Freeway. From the Santa Ana Freeway to its eastern terminus at the intersection of the Pomona, Moreno Valley, and Escondido Freeways, it is named the Riverside Freeway.

Gardena Freeway

The Gardena Freeway is a short freeway in southern Los Angeles County, California. It is the westernmost freeway portion of State Route 91. It begins just west of the Harbor Freeway at the intersection with Vermont Avenue in the eastern edge of the city of Gardena, proceeding eastward approximately six miles (10 km) until it intersects the Long Beach Freeway. Thereafter, SR 91 is known as the Artesia Freeway.

Until 1991, the Gardena Freeway was known as the Redondo Beach Freeway. The name change reflected the successful efforts of the cities of Torrance and Redondo Beach to block the extension of the freeway westward to its intended terminus at the cancelled Pacific Coast Freeway in Redondo Beach.

Artesia Freeway

The Artesia Freeway is a freeway in southeastern Los Angeles County and northwestern Orange County, California. It is signed as State Route 91 for its entire length. It runs east-west from its western terminus at the Long Beach Freeway in northern Long Beach to its eastern terminus at the Santa Ana Freeway at the Fullerton-Anaheim border. (SR 91 continues west of the Long Beach Freeway as the Gardena Freeway, and east of the Santa Ana Freeway as the Riverside Freeway.) The "Artesia Freeway" name originally was assigned to the entire length of SR 91 west of the Santa Ana Freeway in the early 1970s since it was, in sense, the freeway realignment of SR 91 from the paralleling Artesia Boulevard.

As the only freeway to link Los Angeles, Orange, and Riverside counties, the 91 is one of the most heavily congested routes in Southern California.

History

Major cities Bolded cities are officially-designated control cities for signs
Beach Cities (westbound; via Artesia Blvd) Redondo Beach (westbound; via Artesia Blvd) Long Beach (westbound; via I-710) Artesia (westbound) Los Angeles (westbound; via I-5) Riverside (eastbound)

Although the 91 is an east-west road, it inherited its odd (as opposed to even) route number from the now mostly decommissioned U.S. Route 91 (U.S. 91) which passed through the Inland Empire in a northeasterly direction on its way to Las Vegas, Salt Lake City, and points beyond. Those segments of U.S. 91 are now parallel to, or have been replaced altogether by, Interstate 15 (I-15).

Prior to 1991, the Gardena Freeway was known as the Redondo Beach Freeway, referring to Caltrans' original intention for the freeway portion of the route to continue all the way to the never-built Pacific Coast Freeway.

Also, before 1997, the 91 continued all the way to State Route 1 in Hermosa Beach. At that time, the route became discontinuous in Gardena, the portion between Vermont Ave. and Western Ave. being turned over to the city. In 2003, the western portion, from SR 1 to Western Ave. was relinquished to the local jurisdictions. The first segment of the freeway was made in 1965 signed as US 91, and the last segment was made in 1975.

91 Express Lanes

Main article: 91 Express Lanes

By the early 1990s, rapid development of the areas of the Inland Empire around Riverside had made the Riverside Freeway—which is the sole freeway connecting the working class, bedroom communities and industrial areas of the Inland Empire to the wealthy suburbs and commercial centers of Orange County—one of the most congested in the Greater Los Angeles region. In response, a private consortium created the 91 Express Lanes, a fully automated, RFID-activated tollway contained entirely within the median of the existing Riverside Freeway. This route operates between the Orange/Riverside county line and the Costa Mesa Freeway interchange in eastern Anaheim. Opening in 1995, the 91 Express Lanes were the first privately funded tollway built in the United States since the 1940s, and the first fully automated tollway in the world. In 2003, their ownership and operation was taken over by the Orange County Transportation Authority.

Future

Testing evaluations are slated to begin in the winter of 2007 for a tunnel proposal, currently called the Irvine-Corona Expressway proposal. One concept for this project specifies a set of three tunnels—two for cars and one for both trucks and high-speed light rail—that would stretch for 12 miles, burrowing beneath the Santa Ana mountain range, and carrying up to 70,000 cars a day between California’s Riverside and Orange counties. The proposed tunnel project would essentially parallel the 91 freeway and would reduce traffic congestion that has already prompted the need for constructing the 91 Express Lanes. If completed, the Irvine-Corona Expressway would be the longest traffic tunnel in North America.
