The Nevada Department of Transportation (NDOT) is announcing an updated schedule of lane closures on Interstate 15 (I-15) for the ongoing I-15 South Widening Project. These traffic restrictions are necessary for profile grinding, lighting upgrades, and asphalt milling operations. The schedule is subject to change due to weather and other factors.

• Southbound I-15 reduced to two lanes from Silverado Ranch Blvd to St Rose Pkwy
• Northbound I-15 reduced to two lanes from St Rose Pkwy to Silverado Ranch Blvd

Nightly (8:00 p.m. to 5:00 a.m.) Sunday, July 20 to Friday, July 25:
