Route 126 or Highway 126 can refer to multiple roads:
State Route 126 (SR 126) is a highway in Ventura and Los Angeles counties, California. The route runs from U.S. Route 101 in Ventura to Interstate 5 in Santa Clarita through the Santa Clara River Valley. The highway is an important connector highway in Ventura County, and serves as an alternate route into the Santa Clarita and San Fernando valleys, the High Desert of Antelope Valley, and Los Angeles.
State Route 126 is the main route from Ventura County to the San Joaquin Valley via Interstate 5. The highway is officially designated as the Korean War Veterans' Memorial Highway. This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. However, it is not a scenic highway as designated by Caltrans.
State Route 126 generally follows the Santa Clara River through the valley, passing through the towns of Fillmore and Santa Paula. The freeway portion of the highway - called the Santa Paula Freeway - begins in Ventura at U.S. Route 101. It proceeds northeast through the city, interchanging with the western end of SR 118 at a grade-separated interchange. SR 126 then passes through the area of agriculture, orchards, and the Saticoy Oil Field to its northeast, continuing through Santa Paula, where it intersects SR 150, and the freeway portion terminates at Hallock Drive. SR 126 continues as a highway thereafter, known as Telegraph Road. This section extends through Fillmore as Ventura Street, where SR 126 meets SR 23. Following this, SR 126 as Telegraph Road encounters the community of Buckhorn, as well as the edge of Piru and the important historical Rancho Camulos.
State Route 126 (SR-126) is a highway completely within the Ogden-Clearfield metropolitan area in northern Utah that makes a loop around Interstate 15 in its more than twenty-one mile path. The street is given the names Main Street, 1900 West and 2000 West respectively from south to north. Previous to 1977, SR-126 was a road in southern Utah. A portion of the highway is an old routing of US-91.
After its southern terminus, the route heads northwest in Layton. After entering Clearfield, the route turns straight to the north. It continues this direction through Sunset, Roy, and West Haven before veering to the northwest when the highway reaches Marriott-Slaterville. The route again reverts to a northerly direction before reaching Farr West. Just before terminating in South Willard, the route turns northwest one final time.
The entirety of the route, with the exception of a small portion from the Interstate 15/Interstate 84 junction to the northern terminus, lies west of the aforementioned interstates.
