US-95 Lewiston Hill to Thorn Creek Road

ITD is restoring deteriorated pavement along US-95 between Lewiston and Moscow.

Overview

This project will preserve and extend the life of U.S. Highway 95 between Lewiston Hill and Thorn Creek Road by repairing worn pavement and upgrading roadway safety features along the corridor.

Background

US-95 between Lewiston and Moscow has undergone significant improvements over the last several years to create a safer route through North–Central Idaho. Major projects along the corridor have included the new four-lane Thorn Creek to Moscow alignment, which improves grades, reduces conflict points and enhances overall mobility between the two communities.

A highway stretches through rolling hillsides with a green road sign showing distances to Genesee, Moscow and Coeur d’Alene.

Planned pavement work between Lewiston Hill and Thorn Creek builds on those long-term investments by preserving the roadway surface and improving ride quality along an important connection to the modernized corridor.

Construction

Construction on the Lewiston Hill to Thorn Creek Road project is expected to begin in mid-July and continue through September. The project will improve pavement conditions and roadway safety along the corridor through the following improvements:

  • Mill and inlay approximately 90,000 tons of asphalt between mileposts 319.86 and 334.15
  • Repair wheel ruts, cracking and other pavement wear
  • Upgrade guardrail and roadway delineation features
  • Reinstall rumble strips
  • Update roadway striping

During paving operations, some side streets and approaches may temporarily close to allow the new pavement time to cool before vehicles can safely drive on it. Once the paving operation passes an intersection or approach, cross traffic may need to wait briefly before access is restored.

A graphic illustrates the six construction phases for pavement rehabilitation on U.S. Highway 95 between milepost 319 at Lewiston Hill and milepost 334 near Thorn Creek Road. The diagram labels the northbound and southbound lanes and shoulders to show the order in which each section will be reconstructed.

To help keep traffic moving, crews will complete the project one lane at a time. Work will begin in the northbound slow lane at Lewiston Hill (milepost 319) and progress north to Thorn Creek Road (milepost 334) before moving to the next lane.

The project will be completed in the following order:

  • Northbound slow lane

  • Southbound slow lane

  • Northbound passing lane

  • Southbound passing lane

  • Northbound turning lane

  • Southbound turning lane

Project schedule subject to change.
