Designing for current and future needs
Following supportive community feedback, ITD is pursuing a comprehensive plan for improvements to this corridor. Key elements included:
- Innovative intersection designs
- Additional travel lanes and turn bays
- Managed access
Next Steps
Due to traffic volumes and available funding, ITD’s highest priority is to improve the safety and capacity of SH-55 between Farmway and Middleton roads. Improvements here will help address rapid growth and congestion.
SH-55 in Canyon County
SH-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 SH-55 was designed to handle. In many areas, the highway has not been widened since it was constructed in the 1930s.
ITD’s goal is to meet mobility, safety and capacity needs on this corridor from now until 2045.
What this study included
This project began in the summer of 2019 and included:
- Completing a traffic and safety analysis.
- Gathering input from agencies, municipalities and members of the public who have a stake in SH-55.
- Developing plans for managing access on and off SH-55.
- Completing an environmental evaluation.
- Developing preliminary design plans for future projects.
ITD followed 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 SH-55.
