The City of Henderson, in cooperation with the Nevada Department of Transportation (NDOT), is conducting a feasibility study for the I-11/I-515/I-215 Henderson Interchange. This study is following a Planning and Environmental Linkages (PEL) approach, which is intended to shorten the time required to take projects from planning to implementation Decisions made as part of this study could be carried forward into more detailed National Environmental Policy Act (NEPA) studies. The necessary steps have been taken to accelerate planning efforts so that the interchange can begin the NEPA process in 2020. Upon feasibility study completion, the project will be managed by NDOT.

Study Area

The study area limits are I-515, from Sunset Road to Horizon Ridge Parkway, and Lake Mead Parkway, from Basic Road to Stephanie Street.




The I-11/I-515/I-215 Henderson Interchange was constructed in the mid-1990s when Clark County had a population of approximately 1 million residents. With Clark County's population increase to more than 2.2 million, the interchange needs to be improved to accommodate the growing traffic demands.

Project Goals

  • Improve safety, freeway operations and regional mobility
  • Improve air quality
  • Reduce congestion and travel delays

Anticipated Timeline

Upon completion of the feasibility study process, NDOT will continue the project efforts including NEPA, final design, right-of-way acquisitions and construction.

Project Costs

Project costs are still to be determined. One of the initial steps in the feasibility study process is to develop alternative concepts for the project and estimate their costs. These concepts and estimates will be available in mid- to late-2019.

Public/Stakeholder Involvement

Public and stakeholder involvement are integral components of the planning and environmental processes. State, local, and federal agencies as well as property owners, residents, and business owners will be actively engaged in a public review process and provided opportunity for input and comment. Public/stakeholder involvement and outreach will continue throughout the environmental review, design, and construction phases.
