The Nevada Department of Transportation (NDOT), along with the Federal Highway Administration (FHWA) and city of Las Vegas, has begun construction on Project NEON, a public works project that will entail an investment of about $1bn.
Kiewit Infrastructure West Co. is the general contractor for the project under a $559.4m design-build contract, with Atkins North America serving as the project's lead designer.
Project NEON will widen 3.7 miles of Interstate 15 between Sahara Avenue and the ‘Spaghetti Bowl’ interchange in downtown Las Vegas.
At present nearly 300,000 vehicles pass through this route daily, with 25,000 lane changes per hour. Traffic through the corridor is expected to double by 2035.
Project NEON will include an 81ft-tall, 2,606ft-long High Occupancy Vehicle (HOV) flyover bridge that will also accommodate carpool traffic along part of the route.
The project will also convert the two existing I-15 express lanes into a general purpose and HOV lane, thus creating 22 consecutive miles of carpool lanes.
Other proposed upgrades include extending Grand Central Parkway over the Union Pacific Railroad tracks, and connecting to Industrial Road for improved resort corridor access and mobility.
When completed in mid-2019, Project NEON will reduce travel delays by 28%, creating $110m in annual savings through increased productivity. It will create 4,000 jobs in the region.
