Substantial population increases in the Jefferson County area in recent years and known development intentions for the future warrant a need to plan for continued mobility and safety in this region. Movement at the U.S. Highway 20 County Line Road, Rigby and North Rigby Exits, as well as on State Highway 48 and adjoining county roads have all been studied and alternative solutions recommended.


Information and solutions for the future
Jefferson County has consistently ranked as one of the fastest growing counties in Idaho in recent years. This population increase, with even more development anticipated in coming years, means that ITD must plan and work to maintain mobility and safe travel in the area. A study is now complete that has:
- analyzed and assessed impactful areas
- met and coordinated with city and county leaders, developers and business owners
- identified recommended projects, including high- level design
- prioritized the implementation of projects for the future

This document details all of the data used and alternative options considered, as well as gives recommendations based on engineering judgement.

Public Involvement
Community input is an important factor in the success of this study. ITD does not manage all roadways where alternatives are being considered in the process.
Because the alternatives relative to this study involve all parties, opportunities for public involvement will come once more coordination is complete.
