Caltrans and SANDAG are working together to improve the I-805 corridor and provide more transportation choices for the region. The corridor serves some of the most heavily populated communities and key employment centers in the region. It is also critical for international traffic since it begins less than one mile from the U.S.-Mexico border. I-805 provides access to South County cities, San Diego’s urban core, Mission Valley, Sorrento Valley, and the Miramar Marine Corps Air Station. It also connects to major east-west routes providing access to Downtown San Diego and East County cities.
Key projects along the I-805 corridor include creating 28 miles of express lanes in the median of I-805 between SR 95 and I-5, new direct access ramps for buses and other high occupancy vehicles, direct freeway-to-freeway carpool connectors, retaining walls to minimize physical impacts to adjacent communities, and sound walls to reduce noise impacts.
