I-5 Managed Lanes Project (SR-55 to Orange County/Los Angeles County Line)

I-5 Managed Lanes Project (SR-55 to Orange County/Los Angeles County Line)

The California Department of Transportation (Caltrans) is proposing managed lanes improvements in both directions on Interstate (I) 5 from Red Hill Avenue (PM 29.1) to the Orange County Line (PM 44.4) and Los Angeles County Line (PM 0.0) to the City of La Mirada (PM 0.5) in the cities of Tustin, Santa Ana, Orange, Anaheim, Fullerton, Buena Park, and La Mirada. The improvements would modify the existing High Occupancy Vehicle (HOV) lanes within the project limits to address capacity and operational deficiencies. The proposed modifications would improve the overall movement of people and goods along this section of I-5. Four preliminary alternatives, including three Build and the No Build Alternative are under consideration. Alternative 1 is the No Build Alternative, Alternative 2 modifies existing HOV minimum occupancy requirement from the existing two plus to three plus passengers between Red Hill Avenue and the OC/LA County line, Alternative 3 converts existing HOV lanes to Express Lanes between Red Hill Avenue and the OC/LA County line, Alternative 4A will convert the existing HOV lanes to Express Lanes and constructs an additional Express Lane between SR-57 and SR-91 and Alternative 4B will convert the existing HOV lanes to Express Lanes and constructs an additional Express Lane between SR-57 and the OC/LA County line.
