SR-79 Widening Project

Widen a 5.4 mile segment of SR 79 from two to four lanes between Thompson and Domenigoni Parkway

Project Overview

The project is located north of the City of Murrieta, within an unincorporated portion of southwestern Riverside County. The northern end of the project is approximately 4.4 miles east of Interstate 215 (I-215) and the southern end is about 2.8 miles east of I-215.

The SR 79 Widening Project will relieve congestion, improve safety, and provide consistency with other improvements along SR 79.

The SR 79 Widening Project will widen a 5.4 mile segment of SR 79 from two to four lanes between Thompson and Domenigoni Parkway, modify local access, and improve various intersections.

Construction will be performed in two stages, each taking an estimated 12 months to complete. The first stage will take place from Scott Road to Domenigoni Parkway and the second stage will take place from Thompson to Scott Road with intersection improvements at Newport Road.
