The Nevada Dept. of Transportation is ready to rumble with the third and final major phase of Project Neon, a $900-million, 3.7-mile-long widening of Interstate 15 that began in 2016. Nicknamed “The Main Event” and scheduled to begin March 6, the 10-month effort will add mainline and HOV travel lanes, access ramps and 14 bridges from the U.S. Route 95 “Spaghetti Bowl” interchange in downtown Las Vegas south to Sahara Avenue. Kiewit Infrastructure West Co. and Atkins North America lead the design-build team for Project Neon, Nevada’s largest-ever public works construction project. NDOT says the improvements will reduce travel delays in a congested, crash-prone corridor that currently handles 300,000 vehicles daily—a figure projected to double by 2035.
