Expect delays: I-15 project entering last big phase

Traffic is constricted by lane closures related to Project Neon, a nearly $1 billion, 4-mile-long widening of Interstate 15 from the U.S. 95 interchange to Sahara Avenue on Tuesday, March 21, 2017.

Dubbed the Main Event, the final major phase of the Project Neon highway project will get underway next month, the Nevada Department of Transportation announced today.

The last big push, which begins March 6, will affect U.S. 95 and Interstate 15 and is expected to have a bigger impact on traffic than the two previous stages — Car-Nado and the Big Squeeze.

“We do anticipate that there will be delays,” NDOT Senior Project Manager Dale Keller said. “We condensed this into 10 short months out of a four-year contract.”

Project Neon is a nearly $1 billion, 4-mile widening of Interstate 15 from U.S. 95 to Sahara Avenue that began in 2016. It is 60 percent complete and expected to conclude in the summer of 2019.

The Main Event will include restrictions between Sahara and Washington avenues, a half dozen weekend closures of U.S. 95, ramp reductions and detours at the Spaghetti Bowl, and long-term ramp impacts at Charleston Boulevard, D Street and Martin Luther King Boulevard, Keller said.

“The closures are needed for building new freeway travel lanes, on- and off-ramps and 14 bridges,” Keller said.

Spaghetti Bowl ramp impacts include U.S. 95 south at northbound Interstate 15, which will continue to be closed through November, and the southbound U.S. 95 to southbound Interstate 15 ramp, which will be closed from March until November.

Other major ramp impacts along Interstate 15 include the Charleston Boulevard on-ramp to southbound I-15, which will be closed from February until October, and the Martin Luther King Boulevard to southbound Interstate 15/U.S. 95 ramp, which will be closed from March until December.

When completed, Project Neon is expected to reduce travel delays in the area by nearly 30 percent, Keller said.

“We’re going to be knocking out gridlock traffic,” he said. “This next 10 months is going to feature work around-the-clock, six days a week.”

The project is expected to improve safety by reducing merge and weave traffic. The area sees an average of 3.5 accidents a day, according to NODT.

The project also adds dynamic message signs that provide motorists real-time information about detours, accidents and traffic restrictions, NDOT spokesman Tony Illia said.
