The Riverside County Transportation Commission (RCTC) will require an extended full closure of the northbound I-15 Temecula Parkway on-ramp beginning on Sunday, May 11 at 9 p.m. through Monday, May 19 at 5 a.m. This ramp closure is needed to allow crews to safely demolish and reconstruct portions of the on-ramp to provide an additional lane for the I-15 Smart Freeway Pilot Project. The work will require the use of heavy construction equipment during the extended closure.

During the closure, motorists are advised to travel west on Temecula Parkway, northbound on Old Town Front Street, east on Santiago Road, north on Ynez Road, and west on Rancho California Road to enter northbound I-15.

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

Once in operation, the I-15 Smart Freeway Pilot Project will use a dynamic coordinated metering system to allow more or fewer vehicles to enter the highway at a 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.
