I-15 Through Temecula Closures Coming: What Freeway Drivers Must Know

TEMECULA, CA —The Southbound Rancho California Road freeway on-ramp will remain closed for one week, as part of an I-15 lane closure that will last for a full week. It's all in the name of lessening traffic through the pinch-point of Southwest Riverside County.

The I-15 Southbound On-Ramp at Rancho California Road will be closed for a few days, the City of Temecula and the Southwest Sheriff's Station advised. "CalTrans is working on completing new auxiliary lanes on the I-15 through Temecula," a city spokesperson said.

To do so, the southbound Rancho California Road on-ramp will be closed for 7 consecutive days, which started Wednesday night, and will last through Jan 15th at 4 a.m.

"This is necessary to allow day/night crews to safely build retaining walls, barriers, do excavation, etc. Signs have been posted in advance to notify drivers," the city advised.

The new aux lanes will connect:

• Northbound Rancho California Road to Winchester Road
• Southbound Winchester Road to Rancho California Road
• Southbound Rancho California Road to Temecula Parkway

The project is currently ahead of schedule and expected to finish in 2026.
