Work begins on additional lane | WE ARE TEMESCAL VALLEY

map — RCTC completed engineering and environmental studies, as well as the project design, in early 2022. RCTC awarded a construction contract on March 9, 2022. Work began the week of May 23, and will be completed by late summer or early fall. The contract includes incentives for early completion.

Oversized shoulder creates lane between Weirick and Cajalco

Construction has begun for a new lane on southbound Interstate 15 in Corona and Temescal Valley.

Work started the second half of May on RCTC’s I-15 Interim Corridor Operations Project, which will add a non-tolled lane from the Cajalco Road on-ramp to the Weirick Road off-ramp, next to the outer shoulder.

The highway is wide enough to accommodate the new lane, and crews will strengthen the shoulder pavement to handle the weight of traveling vehicles and restripe the lanes. Once completed, southbound I-15 in this area will include four lanes.

RCTC approved a construction contract this spring. The new lane is anticipated to open in three to four months, with financial incentives for the contractor to complete work ahead of schedule.

Although the lane addition is less than one mile, it is expected to help relieve traffic congestion where the 15 Express Lanes end at Cajalco Road. It also will:

Add space for emergency vehicles along the inner shoulder
Add or upgrade guardrails
Improve drainage systems
Install new overhead signs

Drivers are seeing k-rail, reduced lane and shoulder widths, construction signs, and equipment. Please watch for nighttime lane and ramp closures and follow the 55 mile per hour speed limit in the project area.
