The Nevada Department of Transportation (NDOT) has announced a revised schedule for overnight lane closures, essential for the updating of freeway signage throughout the Las Vegas Valley. The updates are part of an extensive project that includes swapping out I-515 signs for I-11 markers across key arteries in the area, such as U.S. 95, U.S. 93, I-215, and certain local roads that stretch from Henderson to Kyle Canyon Road. Detailed traffic restrictions are slated to begin today, at 9:00 p.m. and will cause travelers to encounter reduced lanes and ramp closures intermittently until the early hours of Wednesday, July 2.

According to the schedule provided by NDOT, the upcoming closures will specifically affect the southbound transfer ramp from I-11/U.S. 95 near Ann Rd, the Ann Rd on-ramp, and some lanes on Oso Blanco Rd from Grand Montecito Pkwy to N Durango Rd. To make certain to limit traffic disruptions, the contractor is constrained to a 5-mile work zone per night. This precision, however, does not preempt the possibility of schedule alterations; all planned work is dependent on cooperative weather conditions and other potential factors.

Drivers should anticipate the closures to extend over various segments and ramps and are advised to exercise caution when traveling through the designated work zones. The NDOT recommends considering alternative routes where feasible. Updates on these restrictions and detours have been made available via Waze to assist motorists in navigating around the scheduled work. Furthermore, real-time highway conditions can be queried at nvroads.com or through a designated 511 hotline.

The signage switch comes after the Federal Highway Administration's official designation of I-515 as I-11 back in November 2023, thereby necessitating these updates. The NDOT, in their effort to ensure the public is informed, has coordinated communication through various platforms, including Twitter under handles @NevadaDOTVegas for southern Nevada traffic, and @nevadadot for broader state updates, alongside regular postings on Facebook and Instagram. For those seeking more information, NDOT has urged drivers to engage with their website at dot.nv.gov or to directly call (775) 888-7000 for inquiries.
