DETOUR ROUTE
Detour Route: Motorists may travel east on Rancho California Road, northbound on Ynez Road, and west on Winchester Road to enter northbound I-15.
RCTC, in partnership with Caltrans, the City of Temecula, and the Western Riverside County Council of Governments are implementing an innovative corridor approach for improved traffic operations on northbound I-15 from the San Diego/Riverside County Line in Temecula to the I-15/I-215 Interchange in Murrieta.
Designed as a two-year pilot project, the project is anticipated to improve overall traffic flow and reduce rear-end collisions by maintaining steady travel speeds within the I-15 corridor, without highway expansion and related construction costs and impacts.
