Motorists in Nevada, brace yourselves for a series of lane and ramp closures along the Interstate 15 South, beginning tomorrow night, August 24. Due to the widening projects undertaken by the Nevada Department of Transportation (NDOT), disruptions are expected through the nighttime hours of 8:00 p.m to 5:00 a.m. For those planning a late drive, take note of the restrictions that include northbound I-15's reduction to a single lane from Sloan Rd to Starr Ave, along with closures of the northbound I-15 on and off-ramps to St. Rose Parkway. NDOT has indicated these closures are necessary for roadway improvements such as milling, paving, and loop detector installations.

Following a similar pattern of disruption, closures continue on northbound I-15, which will be constricted to one lane from Blue Diamond Rd to Warm Springs Rd; and the Blue Diamond Rd/I-215 slip ramp to northbound I-15 will be temporarily out of service starting 8:00 p.m. tomorrow, August 24 until 5:00 a.m. the following Monday. The southbound direction is no exception, with scheduled reductions to one lane from Warm Springs Rd to Starr Ave over two nights beginning August 24. Due to favourable conditions, no traffic restrictions are anticipated during the Labor Day weekend, from Saturday, August 30 to Monday, September 1.

NDOT recommends that residents seek alternative routes where possible, to avoid congestion and potential delays caused by the construction work. Utilizing navigational tools such as Waze, which NDOT partners with to inform the public about planned highway impediments, may be beneficial to those needing to navigate the affected areas. The dates and times provided for closures are tentative and may shift depending on the weather or other unforeseeable factors.

For those looking for updates on the state highway conditions, resources are available at the nvroads.com, or via the helpline at 511 - a wise move before heading out. The Nevada Department of Transportation also keeps the public informed with traffic and project updates, especially for those in southern Nevada, through their social media handles @NevadaDOTVegas on X, and across the state via @nevadadot on X, Facebook, and Instagram.
