Constructed in the 1950s and 60s, the I-15 and US-20 interchanges in Idaho Falls have outlived their usefulness. The outdated infrastructure is affecting safety, mobility and economic opportunity in the city, county, and region.

The safety and mobility study includes six interchanges:

1I-15: Exit 118 – Broadway St. to Historic Downtown

2I-15: Exit 119 – US-20, Grandview Dr.

3US-20: Exit 307 – Lindsay Blvd.

4US-20: Exit 308 – Riverside Dr. to City Center

5US-20: Exit 309 – Science Center Dr.

6US-20: Exit 310 – Lewisville HWY

 

The first step will be a planning and environmental study, which is expected to take about 18 months.

Four major goals for this study

  • Collect information about how the project might impact the area.
  • Make data from the environmental study accessible to all.
  • Determine short-, mid-, and long-term improvements as funding becomes available.
  • Develop a solid plan to provide safe and efficient travel for all users.
