I-5 Improvements in North County

In cooperation with Caltrans District 7, the Los Angeles County Metropolitan Transportation Authority is undertaking a project to improve road conditions of Interstate 5 (I-5) as it passes through northern Los Angeles County near Santa Clarita—an approximately 40-minute drive from downtown Los Angeles. The work will extend from the I-5/SR 14 interchange to Parker Road in Santa Clarita and Los Angeles County. This nearly 14 mile stretch covers other major interchanges including State Route 126 and Magic Mountain Parkway. 

Improvements include the addition of high-occupancy vehicle lanes along the median of I-5, the creation of and maintenance of existing truck lanes, and the construction of auxiliary lanes between on-ramps and subsequent off-ramps. The project will also involve intelligent transportation system improvements, including traffic count stations, closed-circuit television cameras, and ramp metering. These improvements will enable the road to handle more traffic at peak hours and provide a safer and faster commute for the residents of northern Los Angeles County. Hill is providing construction management support for these operational and capacity enhancements.
