I-5 / El Toro Road Interchange Improvement Project

The California Department of Transportation (Caltrans) District 12, in partnership with the Orange County Transportation Authority (OCTA), proposes to modify and improve the existing Interstate 5 (I-5)/El Toro Road interchange located in the Cities of Laguna Hills, Laguna Woods, and Lake Forest, in Orange County (County), California. The project limits on I-5 extend from approximately 0.1 miles (mi) south of Los Alisos Boulevard Overcrossing (Post Mile [PM] 17.8) to 0.4 mi north of Ridge Route Drive (PM 19.7), and on El Toro Road from Rockfield Boulevard to Paseo De Valencia, a distance of approximately 1.9 miles. The purpose of the project is to improve existing and future regional mobility and traffic flow to and from the local street network, be consistent with local planning, and consider impacts to right-of-way. In addition, congestion relief on the mainline ramps and local streets would serve to improve mobility

Information in the Inital Study/Environmental Assessment (IS/EA) focuses on the environmental impact evaluation and proposed avoidance, minimization and/or mitigation of potential impacts associated with the proposed Build Alternatives.

The Public Review Period has been extended to May 20, 2019.
