Gov. Steve Sisolak touted the major completion of Project Neon last week after the nearly $1 billion project was declared 96 percent finished, but there’s still some work left to do before the army of orange cones is removed from Interstate 15.

Monday’s openings of the I-15 high-occupancy vehicle lanes, the Spaghetti Bowl HOV flyover ramp and the Neon Gateway, which will connect the carpool lanes with downtown Las Vegas, mark the final major openings associated with Project Neon.

Still, the project won’t be fully finished until July, when a bevy of tasks are complete.

The area that is asked about most by readers — stretches of I-15 that are bumpy and uneven — will be addressed next month.

Crumb rubber asphalt overlay will be placed on I-15, smoothing out the ride in the area. Restriping will be done after the overlay is in place.

Asphalt overlay entails applying a new layer of asphalt to a deteriorating surface instead of tearing up the old asphalt surface entirely. The rubber in the asphalt overlay is derived from used automobile tires and then mixed in with the asphalt. The process uses the existing layers as a base for the new asphalt pavement.

The Nevada Department of Transportation needs to wait to carry out the asphalt overlay, as the temperature needs to be 80 degrees and rising for proper adhesion, said NDOT spokesman Tony Illia.

Also, the 42 active traffic management signs that span stretches of I-15 and U.S. 95 will go online by mid-July. Though they have been in place since the end of February, activating them has taken NDOT longer than expected.

“Obtaining permanent power from NV Energy and the systems integration into the FAST Southern Nevada Traffic Operations Center has taken longer than expected,” Illia said.

Aside from that work, repaving and restriping remains to be done on various portions of roads in the Project Neon area between now and late June.Freeway
