Project Facts

Project Name: I-15, Rose Rd. Interchange
Project Number: A014(002)
Key Number: 14002

Project Description:

This project at I-15 Rose Rd Interchange (Exit 98) will replace the existing bridge over I-15, and update the on- and off-ramps. The need for this project arises from the poor condition of the existing bridge, and the existing exit ramp configuration does not meet current design standards. The purpose of this project is to improve the safety and mobility for the community, agriculture industry, surrounding businesses, freight industry, and the traveling public. This project is planned to be constructed in 2018.

What has happened so far

ITD’s early work on this project focused on looking at alternative locations for the existing interchange (Exit 98). This idea came from local interest in adding another interchange to this part of I-15 after the Rose Rd Overpass bridge collapsed in the 1997 floods. The Rose Road Overpass bridge is south of the Exit 98 Rose Road interchange.

ITD held a Public Information Meeting on August 1, 2013 at Blackfoot City Hall to discuss this project, including potential interchange locations, with the local community. Citizens shared opinions and ideas, and the project design team incorporated the public input into the project development.

The outcome of the public information meeting showed little support for moving the existing interchange, and as of yet, the traffic and planning studies that would allow an informed engineering decision on moving or adding an interchange on I-5 have not been done. Therefore, this project will replace the Rose Rd interchange bridge at the current Exit 98 location.

Bingham County and ITD will need to schedule future planning efforts to determine the viability of an additional interchange north of Blackfoot. ITD is currently working on a Regional Traffic Study for I-15, SH-39, US-26, and US-91 in the Blackfoot area; this will help provide some of the information needed for a decision on adding an interchange on I-15.

What is happening now:

ITD is currently working on alternative layouts for the Rose Road Exit 98 ramps.

What's next:

ITD will invite the community to share their opinions on the proposed ramp layouts at another Public Information Meeting.
