context_page_description: State Route 91 is a major east–west state highway in the U.S. state of California that serves several regions of the Greater Los Angeles urban area. A freeway throughout its entire length, it officially runs from Vermont Avenue in Gardena, just west of the junction with the Harbor Freeway, east to Riverside at the junction with the Pomona and Moreno Valley freeways.
  Though signs along the portion from Vermont Avenue west to Pacific Coast Highway in Hermosa Beach along Artesia Boulevard are still signed as SR 91, the California Department of Transportation no longer controls this portion of the highway, as this segment was relinquished to local jurisdictions in 2003.
  SR 91 inherited its route number from the mostly decommissioned U.S. Route 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 US 91 are now parallel to, or have been replaced altogether by, I-15.
context_section_description: Between the Santa Ana Freeway, Interstate 5 (I-5), in Buena Park and the 91 Freeway's eastern terminus at a junction with Interstate 215 and State Route 60 in Riverside, the 91 Freeway's assigned name is the Riverside Freeway. Past the I-215/SR 60/SR 91 junction, the Riverside Freeway continues as I-215.
  A weigh station is available between the Imperial Highway and Yorba Linda Boulevard/Weir Canyon Road exits.
  In 2003, Caltrans permanently closed off the Coal Canyon Road westbound and eastbound exits and entrances for environmental purposes; however, there are still traces of unmaintained road where the former exit lay, showing evidence that the ramps still exist, available to use as runaway ramps or emergency stops. In 2015, Caltrans permanently closed off the Grand Boulevard eastbound exit and westbound entrance to accommodate the widening of the freeway. If the ramps had stayed open, more businesses and houses would have been demolished. The ramps were scrapped with the widening and there is no emergency exit.
  The Riverside Freeway first opened in 1963 signed as U.S. Route 91 and U.S. Route 395 and the last section was built in 1975.
