The FHWA and Idaho Transportation Department (ITD), in cooperation with the US Army Corps of Engineers (USACE), have prepared a Final Environmental Impact Statement (FEIS) for a highway improvement project in Latah County, Idaho. The project begins near Thorncreek Road (MP 337.67) and continues north for approximately 6.34 miles, ending at the South Fork Palouse River Bridge (MP 344.00). The purpose of this project is to improve the safety and capacity on this segment of U.S.95.

The FEIS analyzes the benefits and effects of the no Action and three Action Alternatives (Modified W-4, C-3 and E-2) on the natural and human environment. It makes corrections to the Draft Environmental Impact Statement (DEIS) published in January of 2013. The FEIS also presents new information and the responses to public comments made during the DEIS public comment period. After intense review and study, the E-2 Alternative was identified as FHWA’s and ITD’s Preferred Alternative in the FEIS.

The FEIS for the U.S. 95, Thorncreek Road to Moscow project is in a 30-day public review period. After the 30-day review is completed, the FHWA will issue a Record of Decision (ROD) for the project.

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 would 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 would:

  • 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 will be crucial to the success of the U.S. 95 Thorncreek Road to Moscow project.
