ITD Projects Southeast Idaho I-15 / I-86 Corridor Study

I-15 / I-86 Corridor Study

Project Facts
Key Number: 9884
Project Number: 22756

The Idaho Transportation Department (ITD) is studying I-15 and I-86 to identify current and future needs throughout the corridors. The study will result in a corridor plan that identifies policies and projects important to the development of these highways over the next 20 years.

Project Description

The completed corridor plan will include an analysis of the existing conditions on the highways; a forecast of future demand over the next 20 years; and a list of short- and long-term improvements on how to modernize transportation. The document will address the course of the highways as a whole and on a county-by-county basis. The plan will be based on community input, engineering analysis, and city, county and agency planning goals. ITD will include the plan in its Idaho Horizons Long Range Capital Improvement and Preservation Program (LRCIP). LRCIP is a planning document that helps ITD prioritize projects for future years.

The finished corridor plan will include:

  • Safety: What improvements will make the highways safer for motorists, pedestrians and residents?
  • Access Management: How can ITD and local communities manage the effect of development along the corridors so the roadways continue to function safely and efficiently?
  • Traffic: What are the best ways to improve current traffic flow and capacity throughout the corridors? Can we anticipate future congestion points and develop solutions?
  • Environment: What are the important environmental issues to consider when ITD builds improvements in the future?
