I-5 Improvement Project from San Diego County Line to Avenida Pico

I-5 Improvement Project from San Diego County Line to Avenida Pico

The California Department of Transportation (Caltrans), in cooperation with the Orange County Transportation Authority (OCTA), proposes improvements to increase person and vehicle throughput on Interstate 5 (I-5) between the San Diego County Line (11-SD-5, PM 71.0) and the I-5/Avenida Pico Interchange (12-ORA-5, PM 3.4) (Proposed Project) in the city of San Clemente and unincorporated San Diego County. The proposed project would add a high-occupancy vehicle (HOV) lane in both directions along this 3.5 mile (mi) stretch of I-5. This Proposed Project would also reestablish existing auxiliary lanes, widen existing undercrossings, and replace two existing overcrossings to accommodate the proposed HOV lanes. This I-5 corridor improvement project is intended to increase vehicle occupancy and vehicle throughput, improve mobility and trip reliability, provide inter-county and regional system connectivity, provide improvements to accommodate projected regional growth, incorporate environmentally sustainable design elements by developing efficient transportation improvements, and improve multimodal efficiency and provide advanced technology to meet the current and future transportation demands. HOV lane and operational improvements have been made on I-5 throughout Orange County north of the project limits. This project is vital to enable the completion of the HOV lane network along the I-5 corridor in Orange County. The need, or current deficiencies of I-5 within the project limits include a lack of HOV lane connectivity from Avenida Pico to the San Diego County Line, and the existing aging facility lacks advanced technology to meet current and future transportation demands. The Proposed Project is currently in the environmental document and preliminary engineering phase. Two alternatives, including one Build and one No Build Alternative are under consideration.
