The I-15 Tropicana Project, previously referred to as the "I-15 / Tropicana Interchange and Harmon High Occupancy Vehicle (HOV) Ramp and Hacienda HOV Ramp Project," is a joint effort project sponsored by the Nevada Department of Transportation (NDOT) and the Regional Transportation Commission of Southern Nevada (RTC). The Federal Highway Administration (FHWA) is also a key partner in the process providing guidance and review of the study’s work products.

The project includes replacing the existing interchange structures to widen and lengthen the Tropicana Avenue bridge over I-15. Other improvements include the replacement of an existing flyover, addition of HOV ramps, and the separation of through traffic on Dean Martin Drive from the Tropicana Avenue intersection.

As part of the National Environmental Policy Act (NEPA), NDOT and the FHWA prepared an Environmental Assessment (EA) for the I-15 Tropicana Project. In February 2020, the FHWA determined that the project will have no significant environmental impacts and issued a Finding of No Significant Impact (FONSI).
