commons=categoryState Route 91, also known as simply The 91, is a major east-west
freeway located entirely withinSouthern California and serving several regions of theGreater Los Angeles metropolitan area. Specifically, it runs fromVermont 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. The route is part of theCalifornia Freeway and Expressway System , and, since the portion west of Vermont Avenue was relinquished to local governments, it is entirely a freeway. SR 91 is part of the State Scenic Highway System from SR 55 to the east city limit of Anaheim, in the western part of theSanta Ana Canyon , [California Department of Transportation , [http://www.dot.ca.gov/hq/LandArch/scenic_highways/route91.htm Route 91 - Scenic Highway] , accessed February 2008] and is eligible for the system through the canyon to I-15.Although SR 91 is an east-west road, it inherited its odd (as opposed to even) route number from the now mostly decommissioned 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).
The area from post mile 10.4 to 11.1 is known as the
Juanita Millender-McDonald Highway.Route description
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 theRiverside Freeway .Gardena Freeway
The Gardena Freeway is a short
freeway in southern Los Angeles County. It is the westernmost freeway portion of State Route 91. It begins just west of the Harbor Freeway at the intersection withVermont 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. 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 theSanta 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 theRiverside 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.
Riverside Freeway
The Riverside Freeway is the assigned name of a segment of State Route 91 (SR 91), a major east-west freeway located entirely within Southern California that links the cities/communities of Orange and Riverside counties. This named segment extends from the
Santa Ana Freeway , Interstate 5 (I-5), in Buena Park to its eastern terminus at its junction with theSan Bernardino Freeway , Interstate 10 (I-10) in San Bernardino. Note that the freeway's number assignment changes to Interstate 215 (I-215) at its junction with the Pomona Freeway, State Route 60 (SR 60) in Riverside. Thus, for the last convert|6|mi|km of its eastern alignment is the Riverside Freeway, Interstate 215. Recent improvements to the I-215/SR 60/SR 91 interchange have included new signs, including a "91 South" sign above the last portion of the I-215 southbound lanes which continue on to become the westbound SR 91. A novel feature, for California, is the presence of the toll road (the91 Express Lanes ) that shares alignment with the Riverside Freeway. The Riverside Freeway was first opened in 1963 signed as U.S. Route 91 and U.S. Route 395 and the last section was built in 1975.91 Express Lanes
Opening in 1995, the 91 Express Lanes was the first privately-funded tollway built in the United States since the 1940s, and the first fully automated tollway in the world. Tolls are collected when a vehicle carrying a transponder mounted on the inside of the vehicle's windshield passes beneath the toll 'booth' (actually a transceiver array above the toll lanes that is located at about the five-mile (8 km) point of the toll road). Other characteristics of the toll road include: variable toll based on traffic volume (i.e. variable congestion pricing) with road signs alerting users to the toll to be paid; an alignment contained entirely within the median of the existing Riverside Freeway with two lanes in each direction; limited access provided only at the east and west ends of the toll road (where the toll lanes become regular
carpool lane s; and separation between the regular, main lanes of the Riverside Freeway is provided by reflective yellow, convert|3|ft|m|abbr=on high, plastic lane markers (as opposed to concrete barriers or a similar solid barrier)).History
Original US 91 - Barstow to Nevada
The Arrowhead Trail, an
auto trail connecting Salt Lake City with Los Angeles, initially took a longer route via presentUS 95 and former US 66 between Las Vegas and Needles, as the more direct Old Spanish Trail was in very poor condition.

(Across the state line, State Route 6 continued through Las Vegas toArizona .) The initial plan for theU.S. Highway system simply stated that Route No. 91 would run from Las Vegas "to an intersection with Route No. 60" (which became US 66 in 1926),Report of Joint Board on Interstate Highways,October 30 ,1925 , Approved by the Secretary of Agriculture,November 18 ,1925 ] but in 1926 the cutoff was chosen, ending at US 66 at Daggett, just east of Barstow., [http://www.lib.berkeley.edu/EART/CA/CA_125k/ Barstow (1934, scale 1:125000)] , [http://cricket.csuchico.edu/spcfotos/maps/topo_search.html Avawatz Mountains (1933, scale 1:250000)] , and [http://www.lib.berkeley.edu/EART/CA/CA_125k/ Ivanpah (1942, scale 1:250000)] ]R 18 - former extension of US 91 through Santa Ana Canyon to Long Beach

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
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 -activatedtollway contained entirely within the median of the existing Riverside Freeway. This route operates between the Orange/Riverside county line and theCosta 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 theOrange 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-speedlight rail —that would stretch for convert|12|mi|km, burrowing beneath the Santa Ana mountain range, and carrying up to 70,000 cars a day between California’s Riverside and Orange counties.
