Welcome
Thank you for your interest in the I-15 Inkom Corridor Online Meeting.
The purpose of the meeting is to provide information and gather input on five proposed projects on I-15 in Inkom. ITD is combining the projects into a corridor-wide improvement to minimize impacts to the public during construction.
This meeting will remain available through September 22, 2020.

Project Background
ITD is proposing to improve I-15 by constructing five projects near Inkom.
Those projects are:
1Union Pacific Railroad (UPRR) Bridge Replacement
2Main St. Bridge Replacement
3Inkom Interchange (West and East)
4Inkom Pavement Improvement
5Business Loop (Old Highway 30) Rapid Creek Bridge Replacement

Constructing the projects together over a 2 year period will minimize overall impacts to the traveling public and allow ITD and the contractor to save time and money.
Project Overview
Public involvement is important to ITD as it moves through the design process on these Inkom projects.
Construction in the corridor is anticipated to begin in 2025.
Refer to the following video to review all planned corridor improvements.
Inkom UPRR Bridge Replacement Overview
The bridges over Old Highway 91 and Union Pacific Railroad (UPRR) are aging and nearing the end of their design life. The new bridge will provide the required height clearances from UPRR’s existing and future tracks.

Main St. Bridge Replacement Overview
The bridges over Main St. are aging and nearing the end of their design life. They have required recent rehabilitation to address deterioration. The clearance under the bridges needs to be increased to meet ITD standards.

Inkom West/East Interchange Overview
The Inkom interchange is what’s commonly referred to as a split interchange with on and off ramps at the west and east end of Inkom functioning as a single interchange.
The structures are aging and need to be replaced within the next 10 years. Rather than replacing the split interchange as is – ITD is considering reconfiguring it by adding an off-ramp for the northbound lanes near Sorrelle Rd. and removing the off-ramp for the northbound lanes at the south end of the interchange.
The Business Loop would still function and would remain in place.
With the removal of the off-ramp, the overhead bridges would no longer be required, and would be removed and replaced with earth fill. This would eliminate bridge replacement costs from this project and eliminate future bridge maintenance costs.

Inkom Pavement Improvement Overview
This project will replace the asphalt starting at the Portneuf interchange and extending 6 miles east to the Portneuf River Bridges. The goal is to replace any pavement that is not upgraded as part of the other improvement projects.

Business Loop Rapid Creek Bridge Replacement Overview
This project will replace the Rapid Creek bridge on the I-15 Business Loop between Commercial St. and Main St. The proposed bridge will address hydraulic issues that have contributed to flooding in the surrounding area.
Construction of the Rapid Creek Bridge replacement will not happen at the same time as construction of the I-15 corridor. The business loop will remain open during I-15 construction.
