The Nevada Department of Transportation (NDOT) has released an updated schedule for lane closures on Interstate 15 as part of the ongoing I-15 South Widening Project. These restrictions are required for profile grinding, lighting upgrades, and asphalt milling operations. The schedule may change due to weather or other factors.
From Sunday, July 20 to Tuesday, July 22, northbound I-15 will be reduced to one lane from Blue Diamond Road to Warm Springs Road nightly from 8:00 p.m. to 5:00 a.m. Additionally, the eastbound Blue Diamond Road to northbound I-15 flyover road will be closed during these hours.
Between Sunday, July 20 and Friday, July 25, northbound I-15 will have one lane open from Sloan Road to Starr Avenue and from Silverado Ranch Boulevard to Blue Diamond Road during the same nighttime hours. Southbound I-15 will be reduced to two lanes from Starr Avenue to St Rose Parkway.
From Monday, July 21 through Friday, July 25, southbound I-15 will be limited to one lane between Warm Springs Road and Blue Diamond Road each night.
Further restrictions are scheduled from Sunday, July 27 through Friday, August 1. During this period, northbound I-15 will be down to one lane from Sloan Road to Starr Avenue nightly.
Ongoing work includes a reduction of southbound I-15 to three lanes between Warm Springs Road and Blue Diamond Road around the clock through July 2025. Similarly, northbound I-15 is reduced to three lanes between Silverado Ranch Boulevard and Blue Diamond Road with an auxiliary lane closed.
