Although Project Neon is nearing its final completion date, traffic impacts related to the largest road project in state history are slated to continue through June.
The final paving and striping work will begin Friday night, with portions lasting until Monday morning, the Nevada Department of Transportation announced this week.
Crews will be applying a special crumb rubber asphalt mix, incorporating shredded tires for a smoother, quieter ride.
“Crumb rubber lasts twice as long as traditional asphalt pavement while also creating a better friction surface with less wet weather splashing,” said Tony Illia, NDOT spokesman. “And it also recycles used tires that otherwise would end up in a landfill.”
The closures are scheduled to continue the following weekend, weather permitting.
NDOT decided to go with full weekend closures because past paving jobs with restricted lane operations on the freeway yielded dangerous results.
In 2011, NDOT resurfaced I-15 between Tropicana and the Spaghetti Bowl with NDOT closing three lanes and leaving two lanes open.
Regional Transportation Commission of Southern Nevada freeway cameras captured vehicles traveling through the work zone at 70 mph and Nevada Highway Patrol troopers wrote about 200 citations for work zone violations in four hours, Illia said.
Also, work production is much higher during a full closure, with the scheduled work taking over a month if carried out with lane restrictions alone, Illia added.
The multiple days of closures, which NDOT dubbed Pave-A-Palooza, includes the following varied weekend closures:
Friday night-Monday morning

■ Detour: I-15 northbound to Sahara, to D Street. The exact route is still being planned out.
The time frame for the roadwork was specifically chosen by NDOT due to minimal special event impacts. Aside from First Friday on June 7 in downtown, there are no major impact events in the city or Clark County, Illia said.
Project Neon, the nearly $1 billion 4-mile-widening of I-15 from Sahara to the Spaghetti Bowl, is 96 percent finished and scheduled for completion by mid-July.
