I-405 Comprehensive Multimodal Corridor Plan (CMCP)

The I-405 is a critical node in our regional transportation system connecting major gateways and trade hubs, but is one of the top ten congested highways in the United States. Metro will lead the development of a comprehensive planning vision for the I-405 in LA County to define shared mobility goals that are responsive to the community’s needs.

The goal of the project is to understand the diverse users and communities relying on and impacted by the I-405 Corridor, solicit their feedback and show how multimodal improvements can reduce congestion, move more people, increase accessibility for all users and support and advance ​equitable outcomes for historically disadvantaged communities.


Metro is in the Early Planning phase of the I-405 CMCP project. Stakeholder engagement is planned at key milestones to prioritize projects, develop the implementation plan, and to vet final materials for the Cycle 3 SCCP grant submittal by Metro.

Metro must prepare qualifying multimodal corridor plans in order to compete for and secure a portion of the $250 million in state funding that is made available through Senate Bill (SB) 1 Solutions for Congested Corridors Program (SCCP). This critical funding supports Metro’s ability to deliver Measure M.
