NDOT breaks ground on $73m Centennial Bowl interchange upgrade


The Nevada Department of Transportation (NDOT) has broken ground on the $73m next phase of the Centennial Bowl interchange in northwest Las Vegas, US.

US Highway 95 meets the 215 Beltway at the Centennial Bowl interchange.

Las Vegas Paving has been appointed as the general contractor for the project. Construction contract is worth $61.5m.

NDOT director Rudy Malfabon said: “This interchange connection greatly enhances traffic, mobility and motorist safety while establishing a new gateway corridor for the Centennial area.

“Currently, over 107,500 vehicles daily travel the ramps and freeways at US 95 and the 215 Beltway, and it’s only expected to grow in the future.”

The project involves the removal of part of the Oso Blanca Road ramp and the old north-to-west loop to make room for three new freeway flyover ramp connections.

These include eastbound 215 Beltway to US Highway 95 southbound as well as southbound US Highway 95 to eastbound 215 Beltway, and northbound US Highway 95 to 215 Beltway westbound.

Flyover ramps facilitate direct freeway-to-freeway connections while maintaining highway travel speeds for greater efficiency and safety.

Moreover, the structures require little right-of-way and eliminate the stop-and-go surface street travel currently needed when navigating the interchange.

Clark County Commissioner Larry Brown, who represents District C, said: “This project helps create a reliable transportation network that enhances cultural and economic access in the northwest valley. It improves accessibility, mobility and safety for residents and businesses.”

Construction involves building the state’s second longest bridge. The 75-ft-tall, 39-ft-wide concrete box girder structure will measure 2,635ft, equivalent of seven football fields.

The two-lane bridge will connect north-to-west freeway traffic and plans also include the construction of a south-to-east flyover equivalent to the length of 26 bowling lanes laid end-to-end.

Other improvements include drainage upgrades and new lighting, landscaping and Intelligent Traffic System (ITS) enhancements.

The project is expected to create 150 jobs during the peak of construction.

The upgrades are being underwritten through a combination of $19m federal funds and $54m state funds. Work is expected to be completed in 2021.
