Retaining Wall and Roadway Construction Began June 2025 on I-105

Summary
Metro is improving traffic flow and safety on the I-105 by converting the existing High Occupancy Vehicle (HOV) lanes into two ExpressLanes in each direction. Major construction for Segment 1—from Sepulveda Boulevard to Central Avenue—began in early 2025 and is expected to continue for approximately three years.

As part of these improvements, crews will construct retaining walls and new roadway pavement on the right-hand shoulder of the freeway to support the future ExpressLanes.
