The I-15 Tropicana Project

Located at the heart of the resort corridor, the I-15/Tropicana Avenue interchange serves as the gateway to the Las Vegas Strip. The combination of new resorts and professional sports has attracted more visitors to the city, drawing as many as 300,000 motorists on major holiday weekends. The widening of the Tropicana interchange will add capacity, improve accessibility to the Strip and allow for the future widening of 1-15 as the population continues to grow.
