North County Comprehensive Multimodal Corridor Plan (CMCP)

CMCPs are data-driven plans to reduce vehicle miles traveled and greenhouse gas emissions and identify mobility solutions in our region's busiest travel corridors. CMCPs include all travel modes in a defined corridor – roadways, public transit, bikeways, and more.

The North County CMCP includes around 700,000 residents and 300,000 jobs in the cities of Escondido, San Marcos, Vista, Carlsbad, and Oceanside, and parts of the county of San Diego, which constitutes about 20% of the region. This plan proposes $8.5 billion of balanced and integrated transportation infrastructure and service improvements. The improvements are expected to reduce transportation related fatalities, decrease daily travel time by an average of 15 minutes, and increase transit ridership from 35,000 to more than 140,000 while meeting regional and state policy goals.

In early 2023, SANDAG and Caltrans released the Draft North County Comprehensive Multimodal Corridor Plan. You can view the final plan and Executive Summary, explore the interactive map at
