ITD's ID-55 Recommended Plan

Idaho 55 in Canyon County

Idaho 55 is a primary transportation and freight corridor through Idaho.

The area around the highway in Canyon County is growing rapidly, causing traffic volumes to increase beyond what Idaho 55 was designed to handle. In many areas, the highway has not been widened since it was constructed in the 1930s.

The goal of this study is to meet mobility, safety and capacity needs on this corridor from now until 2045.

What this study includes

This project began in the summer of 2019 and is expected to last for two years. It includes:

  • Completing a traffic and safety analysis.
  • Gathering input from agencies, municipalities and members of the public who have a stake in Idaho 55.
  • Developing plans for managing access on and off Idaho 55.
  • Completing an environmental evaluation.
  • Developing preliminary design plans for future projects.

ITD will follow the National Environmental Policy Act (NEPA) process throughout this project. The NEPA process is required for ITD to use federal funding for future projects on Idaho 55.
