Project Neon called 40 percent complete

The $1 billion widening of the Spaghetti Bowl freeway interchange, known as Project Neon, is 40 percent complete one year after construction began, the Nevada Department of Transportation said Wednesday.

Roughly 400,000 man-hours of work have been logged without any injuries as work proceeds on Nevada’s largest transportation infrastructure project, NDOT project manager Dale Keller said.

Keller also said work is nearly complete to transform Martin Luther King Boulevard into an “enhanced feeder-like roadway” for Interstate 15 and U.S. Highway 95.

So far, crews have built more than 1 mile of reinforced flood control, demolished 43 structures, laid 17 miles of utility lines, used 607 tons of reinforcing steel and poured

6,342 cubic yards of concrete, NDOT spokesman Tony Illia said.

Commuters can still, however, expect a series of lane restrictions and ramp closures around the Spaghetti Bowl until construction concludes during summer 2019.

Over the next two years, crews will build an 81-foot-tall flyover ramp for high-occupancy vehicles. When completed, the new carpool ramp will have one lane for drivers headed from southbound U.S. 95 to southbound I-15 and another connecting northbound I-15 to northbound

U.S. 95. The two-way concrete ramp, measuring 2,606 feet long, will be accessible from the center lane of both freeways.

Crews also will switch on a dozen new active traffic management signs that will adjust speed limits to help reduce accidents and stop-and-go traffic for the 300,000 vehicles that travel daily between the Spaghetti Bowl and Sahara Avenue.
