I-5 North County Enhancements Project Map

Metro, in partnership with Caltrans District 7, is improving the I-5 freeway from the SR-14 interchange to just south of Parker Road in Castaic. The operational and safety enhancements are in response to expected growth in Santa Clarita—projected to gain over 25,000 new residents by 2035.

Key improvements include:

One new High Occupancy Vehicle (HOV) lane in each direction
Truck lanes in both directions between SR-14 and Calgrove Bl
Auxiliary lanes between selected on- and off-ramps
Intelligent Transportation System (ITS) technology upgrades
Soundwalls at four key locations
Weldon Canyon Bridge replacement

These improvements are part of Metro’s Long Range Transportation Plan and aim to improve mobility and safety for local and regional travelers without adding general-purpose lanes.
