I-15 Express Lanes Project Southern Extension (ELPSE)

I-15 Express Lanes Project Southern Extension (ELPSE)

The Riverside County Transportation Commission (RCTC), in cooperation with the California Department of Transportation (Caltrans) is proposing to construct new lanes along I-15 between post mile (PM) 21.2 and PM 38.1 in Riverside County, California. The primary component of the Project would be the addition of two tolled express lanes in both the northbound (NB) and southbound (SB) directions within the median of I-15 from SR-74 (Central Avenue)(PM 22.3) in the City of Lake Elsinore, through the unincorporated Riverside community of Temescal Valley, to El Cerrito Road (PM 38.1) in the City of Corona, for a distance of approximately 15.8 miles. The Project would also add a SB auxiliary lane between both the Main Street (PM 21.2) Off-Ramp and SR-74 (Central Avenue) On-Ramp (approximately 0.75 mile), and the SR-74 (Central Avenue) Off-Ramp and Nichols Road On-Ramp (PM 23.9) (approximately 1 mile). Along with the lane additions, which would extend from PM 21.2 to PM 38.1, the Project would include widening of up to 15 bridges; potential construction of noise barriers, retaining walls, and drainage systems; and implementation of electronic toll collection equipment and signs. In addition, due to the SB express lanes access between the Cajalco Road and Weirick Road Interchanges, the SB I-15 Weirick Road Off-Ramp would be configured as a dual-lane exit. Associated improvements for the toll lanes, including advance signage and transition striping, would extend approximately 2 miles from each end of the express lane limits to PM 20.3 in the south and PM 40.1 in the north. The proposed lane additions and supporting infrastructure are expected to be constructed primarily within the existing State right of way. No new permanent right of way is expected to be required as part of this Project.
