The Nevada DOT (NDOT) this week awarded a $99 million construction contract to Fisher Sand & Gravel to build ramps, flyovers, and street connections at I-15 and the 215 Beltway in north Las Vegas.

The contractor was also responsible for completing the first section of I-11 in 2018. The new direct system-to-system interchange will greatly improve traffic, enhance safety, and increase mobility.

According to NDOT, the project entails building two massive cast-in-place concrete dual-lane flyovers, among other structures, including a 51-ft-tall, 1,800-ft-long east-to-north connection that will be the equivalent of five football fields laid end-to-end. The northbound I-15 to westbound 215 flyover, meanwhile, will be longer than the Eiffel Tower laid on its side. The structures sit atop a network of drilled pilings that reinforce the subsurface, with the largest measuring 10 ft in diameter and 104 ft in depth. Atkins is the project designer.

The improvements also entail new I-15 southbound on- and off-ramps at Tropical Parkway for greater access as well as widening over a half-mile of Beltway from four to six travel lanes. Other upgrades call for extending Tropical Parkway to Centennial Parkway, replacing Range Road as an east-west surface connection, with a new eastbound 215 Beltway off-ramp to the new Centennial Parkway and Range Road intersection.

The interchange currently averages about 34,000 vehicles daily, although future traffic counts are expected to grow by 72% over the next two decades. The project, whose work area covers nearly 2 miles, will break ground during the first quarter with anticipated completion in late 2022. The enhancements are 95% funded by the federal government with the state providing the remaining monies.
