I-15/Railroad Canyon Road & Franklin Interchange Project

The Project:

The Interstate 15 Railroad Canyon Road Interchange is a significant regional transportation corridor, serving the cities of Lake Elsinore, Menifee, Canyon Lake and the County of Riverside. Due to the continuous growth in the area, for many years this interchange has faced increased traffic congestion and unnecessary delays for travelers. The current design can no longer adequately serve the community.

In cooperation the Riverside County Transportation Commission (RCTC) and Caltrans,  construction of the Interstate 15 Railroad Canyon Road Interchange project is expected to begin on May 18, 2020. RCTC is the lead agency on this project, which is expected to take up to two years to complete. 

The project should reduce trip times and improve traffic circulation and capacity for on and off ramps at the interchange. It will also improve the level of service for the Grape Street/Summerhill Drive and Railroad Canyon Road Intersection.

Below are key components of the approved Northbound Hook Ramp design for the Interstate 15 Railroad Canyon Road Interchange project.
