I-405 Sepulveda Pass ExpressLanes
Reducing traffic congestion for one of LA’s most heavily traveled corridors.

Estimated Project Completion
2035
Metro and Caltrans are planning ExpressLanes on the I-405 between I-10 and US-101 through the Sepulveda Pass—one of the most congested corridors in the country. The project would convert existing carpool (HOV) lanes into High-Occupancy Toll (HOT) lanes and, potentially, a second managed lane in each direction to improve reliability, safety and person throughput. ExpressLanes use dynamic tolling to ensure more consistent travel times and to give travelers—including carpoolers, transit riders and toll-paying drivers—more predictable options. The project also advances regional efforts to create a connected ExpressLanes system across LA County. Metro is also looking at alternatives such as a no-build option, various lane configurations and operational approaches. Community feedback continues to inform planning and environmental review, with the Final Environmental Impact Report/Statement (EIR/EIS) expected in 2026.
