Lots Of Cone Zones, A Closure And Lane Restrictions Line Streets Of Southern Nevada

Southebound Interstate 15 To Close Between Sahara And Spring Mountain Road

September 11, 2018 - 1:24 pm

LAS VEGAS, NV (KXNT) - The Nevada Department of Transportation (NDOT) will close Interstate 15 southbound between Sahara Avenue and Spring Mountain Road from 11 p.m., September 12, until 5 a.m., September 13, in Las Vegas. Additionally, the Sahara Avenue onramp to Interstate 15 southbound will be closed from 9 p.m., September 12, until 6 a.m., September 13.

The temporary closures are needed to install overhead Active Traffic Management signs as part of “The Main Event,” the third and final phase of work for Project Neon’s nearly $1 billion 4-mile-long widening of Interstate 15 from the U.S. 95 interchange to Sahara Avenue. Project Neon is 81 percent finished and scheduled for substantial completion in the summer of 2019.

Motorists should use caution while traveling through the work zone, heed construction signage, and take alternate detour routes, if possible. Check the Project Neon website ( or Facebook, LinkedIn, and Twitter pages (@NDOTProjectNeon) for up to date information. There is also a free smartphone app available, plus a hotline available in both English and Spanish at 702-293-NEON (6366). NDOT works with Waze to inform the public about planned highway restrictions, but unscheduled construction changes, closures, and restrictions are possible due to weather or other factors. For the latest state highway conditions, visit or call 511 before driving.


Transportation officials will reduce Interstate 15 at U.S. Highway 93 to one lane in each direction from 7 p.m. until 7 a.m. nightly, starting the evening of September 10 and continuing through the morning of September 12, in Clark County. Additionally, U.S. Highway 93 will be closed under Interstate 15 during the same days and times; however, all Interstate 15 ramps will remain open. 

The temporary closures are needed for bridge construction as part of the new $58 million Interstate 15 / U.S. Highway 93 Garnet Interchange project that broke ground earlier this year. Plans call for building a modified diverging diamond interchange, plus widening U.S. Highway 93 from a two-lane highway to a four-lane divided highway for five miles from the new Garnet Interchange to just north of Apex Power Parkway, among other improvements. The project should reach substantial completion by December. 


Officials with NDOT will be holding a public meeting on what's called the Tropicana Avenue Improvement Project.  

The informational meeting will be in Las Vegas, and it will be about the planned East Tropicana Avenue (State Route 593) improvements between Las Vegas Boulevard and Boulder Highway, including an updated road surface, reconfigured median islands, enhanced lighting, and improved handicap accessibility with sidewalks and ramps. The meeting will inform the traveling public about the project scope and details as well as lane restrictions and travel impacts. 

The meeting will go from 4-7 p.m., Wednesday, September 12, 2018. A presentation will be made at 5:30 p.m., followed by a brief question and answer period. The meeting will be conducted in an open house style with displays, maps and project staff.

It will be held at the Cambridge Community Center, located at 3930 Cambridge Street in Las Vegas.

Officials from NDOT said this project will address increased vehicle and pedestrian travel in a mature urban corridor, improving operational efficiency and enhancing safety, and everyone is encouraged to attend. Comments may be submitted for the public record in writing at the meeting or verbally to a court reporter who will be present at the meeting. (A Spanish translator will be available during the meeting). Written or emailed comments will be accepted through 5 p.m., Friday, September 28, 2018. Please direct comments to Devin Cartwright, P.E., Nevada Department of Transportation, 1263 S. Stewart St., Carson City, NV 89712; email:
