IDAHO TRANSPORTATION DEPARTMENT
U.S. 95, Thorncreek Road to Moscow Project

Project Introduction

Thank you for your involvement in the Idaho Transportation Department’s (ITD) U.S. 95, Thorncreek Road to Moscow Project. The U.S. 95, Thorncreek Road to Moscow project will replace approximately 6.5 miles of the existing two-lane roadway with a new four-lane divided highway. The project is expected to improve safety and highway capacity.

U.S. 95 is one of Idaho’s most important highways. It serves as the primary link between northern and southern Idaho, and it provides the backbone for all our transportation needs including commercial, agricultural, recreational and residential traffic.

For this project, ITD will:

  • Add two lanes in each direction. The lanes would be divided by a 34-foot median in the rural section.
  • Add a 12-foot center turn lane and curbs, gutters and sidewalks in the urban section just south of Moscow.
  • Improve many of the curves and make the grade less steep.
  • Widen the shoulders.
  • Add right- and left-turn lanes at county road intersections.
  • Add ditches that will keep rain and snowmelt from collecting on the roadway.
  • Combine current access points when possible and limit the number of new intersections and driveways.
  • Add a 30-foot clear zone. The clear zone is the flat area outside the shoulder. It provides a safe area if a vehicle goes off the road.
  • Improve stopping distance by reducing curves. This will allow drivers to see more of the roadway ahead.

We encourage you to stay involved, provide your input and look for project updates on our website. Your involvement is crucial to the success of the U.S. 95 Thorncreek Road to Moscow project.

Fall/Winter 2016 Update

The Idaho Transportation Department (ITD) is in the process of addressing a legal challenge to the Environmental Impact Statement for the U.S. 95 Thorncreek to Moscow project.  Over the next several months ITD will not only be addressing the legal challenge but will be in contact with all the property owners impacted by the project.

The Idaho Transportation Department received a signed Record of Decision (ROD) from the Federal Highway Administration in March of 2016.  The ROD gives ITD authority to purchase land and begin the final design phase of the project.

Construction could begin as early as the fall of 2017.

FHWA and ITD evaluated many alternatives for the new highway alignment, including western, central and eastern routes. The final eastern route (E2) was chosen after a multi-year environmental review process. The Idaho Transportation Department (ITD) appreciates everyone who participated in the environmental process and submitted comments.
