Interstate 15 Smart Freeway Pilot Project

Status: Pre-Construction

Location: Western Riverside County

Type of Project: Highways

Location: Northbound Interstate 15 from the San Diego/Riverside County Line in Temecula to the 15/215 Interchange in Murrieta

Engineering/Environmental Studies: Anticipated to begin in 2021

Construction: Could begin in 2022

Investment: $18 million (total project cost)


RCTC, in partnership with Caltrans, will conduct engineering and environmental studies for the Interstate 15 Smart Freeway pilot project on northbound Interstate 15 from the San Diego/Riverside County Line to the 15/215 Interchange in Murrieta.

The project would help improve safety and maintain a steady flow of traffic for this eight-mile section of roadway that has frequent congestion, especially during peak afternoon commute times. State of the art technology would track traffic on the roadways while adjusting ramp metering. The system would also provide real-time traffic flow information to motorists.

Once funding and environmental approvals are secured, construction could begin in 2022. RCTC is seeking federal, state, and local funding sources.
