The project is located within the limits of the City of Los Alamitos, in Orange County, on I-605 from PM 1.1 to 1.6. The I-605/Katella Avenue Interchange is located approximately 1.3 miles north of the I-405/I-605 junction, and approximately 5 miles south of State Route 91 (SR-91). Within the vicinity of the proposed project, I-605 has four general purpose lanes in each direction and one high occupancy vehicle (HOV) lane in each direction. From the I-405 interchange to Katella Avenue, there is an auxiliary lane in each direction and a sound barrier along the northbound right shoulder. The purpose of the proposed project is to improve interchange traffic operations, and improve pedestrian and bicycle facilities within the project limits.
