I-15 Inkom Corridor Improvements

ITD is planning and designing several improvements to Interstate 15 (I-15) in Bannock County, in and near the City of Inkom.

In an effort to minimize impacts to those who live, work, and travel through the Inkom Corridor, ITD plans combine these projects into a corridor-wide improvement effort during construction. ITD hopes to reduce construction time to approximately 2 years, rather than extending it over several years. Benefits of combining projects include less disruption to the traveling public and the most efficient use of construction funds.


Over the past year, ITD invited the community to take part in the decision-making process. Initially, ITD planned to construct five projects in the area. Feedback from an online public meeting, community working group and the city-wide mailing showed the community felt positively about area improvements, but not in favor of reconfiguring the Inkom Interchange.

ITD considered the public input gathered and held discussions with City of Inkom leaders and the Federal Highway Administration (FHWA) before deciding to leave the interchange as is.

The new Interchange Decision and Corridor Update tri-fold mailer are available in the Downloads and Resources section.
