The fourth corner was home to Tropicana, which Tropicana Avenue is named after; it closed on April 2, 2024, and was demolished by implosion on October 9 to make way for a new Bally’s Las Vegas[1] and a new baseball stadium for the Oakland Athletics after they relocate to Las Vegas.

Tropicana Avenue is also the main local street into Harry Reid International Airport and the first major exit from I-15 to the Strip for traffic heading north from the Los Angeles and San Diego areas.

The heavy local traffic on Las Vegas Boulevard, which is listed as a National Scenic Byway All-American Road, further adds to the number of vehicles in this area, making the intersection one of the busiest in the nation.

Tunnels were considered, but being enclosed and underground posed extra security risks.
