South Bay to Sorrento

South Bay to Sorrento – Purple Line/I-805/Blue Line/I-5 South

The South Bay to Sorrento (SB2S) Comprehensive Multimodal Corridor Plan (CMCP) studied ways to improve transportation safety, increase travel choices, and improve mobility.

The plan aims to guide development of an innovative transportation network, transforming the way people and goods move through the San Diego region. The CMCP evaluates all travel modes and transportation facilities in a defined corridor – highways and freeways, parallel and connecting roadways, transit (bus, bus rapid transit, light rail, intercity rail, etc.), pathways, and bikeways.

The 28-mile South Bay to Sorrento corridor is one of the most congested and heavily used corridors in San Diego County. The study area includes the cities of San Diego, Chula Vista, Coronado, National City, and Imperial Beach.

Major transportation facilities that pass through the study area include Interstate 5, Interstate 8, Interstate 805, State Route 52, State Route 54, State Route 94, State Route 905, major arterials and the Bayshore Bikeway. Existing transit services include the COASTER, the Trolley, multiple Rapid lines, and more than 25 local bus lines.

Efforts Underway

The project team has defined how the corridor is currently performing and examined why it is performing this way. With this analysis, the project team has recommended projects and strategies that integrate active transportation, transit services, and the deployment of technology to better manage traffic and incident management needs throughout the corridor’s planning area.

About Comprehensive Multimodal Corridor Plans

CMCPs are data-driven plans to reduce vehicle miles traveled and greenhouse gas emissions, generate transportation choices, and preserve community character while creating opportunities for enhancement projects. CMCPs include all travel modes in a defined corridor – roadways, public transit, bikeways, and more. View the CMCP corridor map.

CMCPs are the implementation blueprints that take the transportation vision of 2021 Regional Plan and explore the programs and projects that can be developed to make it a reality.
