RIVERSIDE, Calif. – The Riverside County Transportation Commission (RCTC) will implement a full closure of the Rancho California Road direct on-ramp to northbound I-15 in Temecula. The closure will begin on Monday, June 23 at 9 p.m. and remain in effect through Tuesday, July 1 at 5 a.m. This closure is necessary to allow crews to safely demolish and reconstruct portions of the on-ramp for the I-15 Smart Freeway Pilot Project.

During these closures, crews will extend a second lane of the on-ramp by several hundred feet and create a safety pocket for emergency vehicles. The work will also involve reconfiguring and realigning the ramp to create a merge point between the loop and the direct on-ramps for Rancho California Road.

RCTC will require a similar closure of the northbound 15 Rancho California Road loop on-ramp in July.

During the extended full closure, motorists are advised to travel west on Rancho California Road, northbound on Jefferson Avenue, and east on Winchester Road to enter Northbound I-15.

Closure dates are subject to change due to weather, site conditions, construction progress, and other factors.

Once operational, the I-15 Smart Freeway Pilot Project will use a dynamic, coordinated ramp metering system to regulate the number of vehicles entering the highway at any given time, allowing for a smoother traffic flow on the northbound 15. The system is designed to improve traffic and reduce collisions on the eight-mile stretch of the northbound I-15 from the County Line in Temecula to the I-15/I-215 Interchange in Murrieta.
