The Riverside Freeway is the assigned name of a segment of California State Route 91 (CA/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 the San 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, California State Route (CA/SR-60) in Riverside. Thus, for the last 6 miles of its eastern alignment is the Riverside Freeway, Interstate 215. A novel feature, for California, is the presence of the toll road (the 91 Express Lanes) that shares alignment with the Riverside Freeway.
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 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 (2) lanes in each direction; limited access provided only at the east and west ends of the toll road (at which point the toll lanes become 'regular' carpool lanes; and separation between the regular, main lanes of the Riverside Freeway provided only by reflective yellow, 3' high, plastic lane markers (as opposed to concrete barriers or a similar 'solid' barrier). Legal definition Routes 91 and 215 from Route 5 to Route 10.
