Proposed/future Freeways

Caltrans or local transportation agencies have identified the following priority freeway projects:

• A new freeway across the Santa Ana Mountains to relieve congestion on State Route 91, Riverside Freeway, and provide a route between the Inland Empire and southern Orange County.
• A new freeway, the Mid County Parkway from Perris to San Jacinto.
• Extension to Interstate 710, Long Beach Freeway, to its originally planned terminus at Interstate 210, Foothill Freeway, in Pasadena, via a tunnel underneath the city of South Pasadena.
• An extension to the State Route 241 toll road to meet Interstate 5 in San Clemente.
• An extension to State Route 905/future Interstate 905 to reach the Otay Mesa border crossing, with a junction at State Route 125 and future State Route 11.
• Upgrade to State Route 71, Chino Valley Freeway, north of State Route 60, Pomona Freeway, to Interstate 10, San Bernardino Freeway, in Pomona.
• Upgrade to State Route 55, Costa Mesa Freeway, from south of its current freeway terminus at 19th Street in Costa Mesa to State Route 1, Pacific Coast Highway, in Newport Beach, potentially via a tunnel.
• Construction of the High Desert Corridor, a freeway and expressway between State Route 14, Antelope Valley Freeway, in Palmdale and Interstate 15, Mojave Freeway, near Victorville
• Addition of high occupancy vehicle and high occupancy toll lanes to freeway segments currently lacking them.
• Construction of lower-inclined alternate alignments on steep segments of freeway, to enable trucks to climb mountain passes more easily and speed up the flow of automobile traffic.
