Allegiant Stadium transportation improvement project worth the wait Mick Akers, Las Vegas Review-Journal · December 2, 2019 at 1:50 pm With the final public meeting in the books, a major road project that will help traffic flow to and from Allegiant Stadium is on schedule to begin in 2021, a year after the facility opens. The $200 million Interstate 15/Tropicana Avenue interchange project has been heralded as a major gameday and event-day road improvement project, but many Las Vegans have complained that the project won’t start until a year after the stadium begins operating and isn’t scheduled for completion until fall 2024. Game days and major events at the 65,000-person capacity stadium are projected to bring an additional 15,000 to 18,000 vehicles to the roadway system in the vicinity, according to the Nevada Department of Transportation. The project was in the works even before the Raiders’ relocation to Las Vegas was whispered about, and it does not create any additional fiscal impact on the state Department of Transportation. But the timeline was accelerated once the $2 billion stadium, near I-15 and Russell Road, became a reality.
