Last week, a ceremony held at the Allegiant Stadium to launch the I-15/Tropicana interchange upgrade project. The multi-year, $305-million project, which will create more than 4,600 jobs, was funded in part with money from the bipartisan Infrastructure Investment and Jobs Act (IIJA), signed by President Biden in 2021.
The Tropicana/I-15 interchange opened more than 60 years ago and though it has been updated several times it has outlived its useful life.
U.S. Transportation Secretary Pete Buttigieg joined Nevada Gov. Steve Sisolak, Nevada Department of Transportation (NDOT) Director Kristina Swallow, Senator Cortez Masto, Congresswoman Susie Lee, Congressman Steven Horsford and other community leaders at the ceremony.
Gov. Sisolak noted the improvements are going to reduce crashes and improve mobility at the gateway to the Las Vegas Strip. He also touted the nearly $30 million for the project that comes from the IIJA. "We're going to see 2.7 billion dollars heading (to Nevada) just for the highway piece alone in federal funding in the next five years," he said.
Improvements of the I-15/Tropicana Interchange project include:
- Widening Tropicana Ave. to four lanes from west of Dean Martin through Las Vegas Blvd.
- Raising the Tropicana Ave. bridge over I-15 to meet modern height requirements.
- Lengthening the Tropicana Ave. bridge to accommodate future widening of I-15.
- A new HOV half-interchange on the south side of Harmon Ave.
- A new alignment for Dean Martin Dr. under Tropicana for improved traffic flow.
- New pedestrian walkways, lighting, and safety enhancements, including widening sidewalks from 5’ to 10’.
- New Active Traffic Management (ATM) signs on I-15 between Warm Springs Rd. and Flamingo Rd.
