Interstate 5/El Toro Road Interchange Project

The project involves modifying and improving the Interstate 5 interchange between post miles 17.8 and 19.7 in Orange County, California, spanning the cities of Lake Forest, Laguna Woods, and Laguna Hills. Covering approximately 1.9 miles of I-5, the work focuses on enhancing traffic flow, reducing ramp queuing, optimizing traffic signals, and improving mobility at adjacent local intersections. Two build alternatives are under consideration: Build Alternative 1, which includes southbound I-5 hook ramps with design option 1a, and Build Alternative 3, which emphasizes traffic system management and traffic demand management strategies, alongside the No-Build Alternative as a baseline. The initiative aims to integrate technology to better manage traffic demand and alleviate congestion in a high-traffic corridor. The project is led by Caltrans District 12–Orange, with Gabriela Duran, Associate Environmental Planner, serving as the primary point of contact. The contract is listed as a forecast dated August 5, 2026, and the place of performance is in the 92653 zip code area. While no solicitation number or NAICS code is provided, the initiative is being developed under California’s environmental review processes, as indicated by the CEQA Net project link. The scope reflects a multimodal approach to transportation improvement, balancing infrastructure changes with operational enhancements to meet future traffic demands in a densely populated region.
