Project Overview Fact Sheet

I-5 North Capacity Enhancements Fact Sheet


Metro (Los Angeles Metropolitan Transportation Authority), in cooperation with Caltrans District 7, is conducting final design for the proposed High Occupancy Vehicle lanes and extension of the truck lanes along Interstate 5 (I-5) from State Route 14 (SR-14) to south of Parker Rd in north LA County. These improvements are part of a multi-phase project identified in Metro’s Long Range Transportation Plan as I-5 North Capacity Enhancements. The design phase will occur from Summer 2016 to Winter 2018, with construction estimated to occur Late Summer 2019 through Summer 2022.

I-5 Improvements in North County

What’s Involved

The project entails capacity enhancements along the I-5 freeway in the Santa Clarita area from the SR-14 interchange to Parker Rd. The enhancements include the addition of HOV (carpool) lanes along the median, extension of the northbound truck lane from Gavin Canyon undercrossing to Calgrove Blvd off-ramp, addition of the southbound truck lane from Calgrove Blvd on-ramp to SR-14, and the addition of auxiliary lanes (additional outside lanes extending between an on-ramp and a subsequent off-ramp). The additional 14-mile HOV lanes in both directions would extend existing carpool lanes on the I-5 freeway in San Fernando Valley to Santa Clarita Valley.

Sound Walls

Sound walls will be constructed along the freeway. The locations of sound walls are determined based on noise studies.
