The "I-15 / Tropicana Interchange and Harmon High Occupancy Vehicle (HOV) Ramp and Hacienda HOV Ramp Project" has been renamed the "I-15 Tropicana." It continues to be a joint effort project sponsored by the Nevada Department of Transportation (NDOT) and the Regional Transportation Commission of Southern Nevada (RTC).TropHH_logo update HR The Federal Highway Administration (FHWA) is a key partner in the process providing guidance and review of the study’s work products.

The I-15 Tropicana project has been renamed and revised to address several key comments from local property owners and stakeholders. During the past year, our team has re-evaluated and re-configured the I-15 HOV access locations. Previously, HOV access was provided to and from the south at Hacienda and to and from the north at Harmon. Now that access has shifted, removing access at Hacienda and changing the access at Harmon so that it is to and from the south.

Study Area

The study is currently evaluating operations and potential improvements along I-15 from Russell Road to Flamingo and east-west on Tropicana Ave. and Harmon from Valley View to Las Vegas Boulevard.



The project objectives are as follows:

  • Prepare an environmental review of the proposed project improvements and their potential impacts and measures to mitigate those impacts.
  • Improve the safety of the Tropicana interchange and on I-15 in the vicinity of the interchange
  • Improve operations of the Tropicana interchange while enhancing the performance of the ramps and intersections. This means travelers will be able to get to their destinations faster
  • Introduce HOV Access at Harmon to and from the south
  • Determine potential impacts to local businesses and resort destinations and provide early and upfront information to those affected

Stakeholder Outreach

Stakeholder outreach is an integral component of the environmental process. State, local, and federal agencies as well as property owners, residents and business owners have been actively engaged in a Public Review process and provided opportunity for input and comment. The project will document all stakeholder outreach performed. Stakeholder outreach will continue throughout the environmental review, design, and construction phases.

The project is currently in the environmental review phase of project development. This phase ensures NDOT and FHWA compliance with the National Environmental Policy Act (NEPA).
