Work has begun on the final phase of Nevada’s largest interchange project.

The Centennial Bowl project in Las Vegas, which began in 2015, will consist of 20 bridges over three decks when it is completed in 2024, according to the Nevada Department of Transportation.

The final $155 million phase involves completing three remaining ramps at the intersection of U.S. 95 and the 215 Beltway in northwest Las Vegas. The current interchange is traveled by 107,500 vehicles a day, with more traffic expected in the future, NDOT says.

The project will include these new direct freeway connections:

  • southbound U.S. 95 to westbound 215 Beltway
  • westbound 215 Beltway to northbound U.S. 95
  • eastbound 215 Beltway to northbound U.S. 95.

The ramp from northbound U.S. 95 to eastbound 215 Beltway will be widened to two lanes, and a half-mile section of the 215 Beltway will be expanded to a six-lane divided freeway, NDOT says.

“The project’s new direct freeway-to-freeway connections enable higher travel speeds for greater efficiency and safety that also forgoes the current stop-and-go surface street navigation,” said NDOT spokesman Tony Illia. “Additionally, project improvements will also provide a higher degree of local connectivity that doesn’t currently exist.”

The project is expected to create “1,700 direct, indirect and induced local jobs,” according to NDOT.

Another feature of the final phase: a multi-use recreational trail along the north side of the 215 Beltway from Grand Montecito Parkway to Tenaya Way, along with several miles of new bike lanes and sidewalks, NDOT says. The new interchange also has the state’s second-longest bridge.

Las Vegas Paving Corp. is the general contractor on the final phase.
