The southbound I-5 Calgrove Boulevard on-ramp in Santa Clarita will temporarily close for 30 days to allow construction crews for the I-5 North County Enhancements Project to upgrade pavement, install new guardrails and perform utility work.

The on-ramp will begin its closure on May 5 and is expected to reopen on June 4.

Local motorists are advised to allow extra travel time and follow recommended detours.

The I-5 North County Enhancement Project is designed to:

-Enhance safety and traffic flow for motorists and freight trucks along the corridor.

-Relieve bottlenecks and improve overall mobility.

-Support future growth in the Santa Clarita Valley and promote long-term economic development throughout North Los Angeles County.

This $679 million highway project is one of L.A. Metro’s key Twenty-Eight by ’28 initiatives and is expected to be completed by 2026, well ahead of the 2028 Olympic and Paralympic Games in Los Angeles.
