US-95: Intersection Improvements

This project will improve mobility through this highly-used corridor by achieving uniform signal spacing and adding capacity on side streets.

Work in 2019 included construction of: ADA improvements, the shared-use path, noise walls, changes to non-signalized intersections, removal of the Bosanko signal and the Wilbur  extension.

In 2020, turn lane construction will start at Neider Avenue in April and work north toward Miles Avenue until completion in October.

Extension of Wilbur Avenue will take place until September, though the new portion won’t be open until a signal is installed late this summer.

Later this season, the signals at Kathleen, Wilbur and Miles will be installed, and the Canfield signal will be removed and replaced with a curbed median.

Most work will take place during the day, though some nighttime work is planned when constructing improvements near drive-throughs or working on signals. No weekend work is expected.

2020 impacts

Bike traffic will be detoured onto Government Way during construction of the path and noise walls.

During ADA upgrades and path reconstruction, pedestrians will be able to detour to nearby intersections or follow on-site instructions to call (208) 771-8569 or (208) 661-9191 for assistance. Those requiring assistance are advised to call ahead if possible; otherwise they may wait up to 30 minutes for help. Assistance will be available 7 days a week from 6 a.m. to 9 p.m. Notices will be published in the CDA Press prior to closures.

Turn lane construction will likely cause more congestion with some temporary lane closures on side streets possible.


Changes to signalized intersections

Thousands of vehicles travel on the highway every day to access nearby destinations, creating localized congestion that cannot easily be solved. Rather than expanding the highway and significantly impacting local businesses, ITD will remove some signals and add other signals to achieve consistent half-mile spacing between them. A 2005 study examined signals throughout the corridor and recommended this spacing because it adds the capacity of an extra lane without actually committing resources to do so.

The existing quarter-mile signal spacing of some of the signals is too close and causes traffic to backup into previous intersections, hindering the signals’ ability to regulate flow. Uniform signal spacing of at least a half-mile is optimal, as it accommodates various traffic flows and improves travel time, safety and fuel consumption.

Signals at Bosanko and Canfield avenues will be removed, and signals will be installed at Miles and Wilbur avenues.

Changes to crossings

Movements at non-signalized intersections are now guided by small, curbed medians. Drivers on the highway can turn right or left across traffic, but drivers on the side street can only turn right onto the highway. They cannot cross traffic or turn left from a side street, improving safety by reducing conflicts and controlling access.

Drivers on side streets can make U-turns at the nearest signal on the highway–often only one-quarter mile away–to access businesses on the other side of the highway. They may also seek other local routes.

Side street capacity

Adding capacity on side streets will improve traffic flow by allowing vehicles to move in a more organized manner.

  • At Neider Avenue: right turn lane added to head north
  • At Kathleen Avenue: right turn lanes added to head north or south, and additional left turn lane on US-95
  • At Dalton Avenue: right turn lane added to head north
  • At Hanley Avenue: lane added for westbound through traffic on Hanley Avenue
  • At Wilbur Avenue: street extension, new signal and right and left turn lanes in all directions
  • At Prairie Avenue: right turn lanes added to head north or south, and a second left turn lane added on US-95
  • At Hayden Avenue: right turn lane added to head south
  • At Miles Avenue: new signal and right and left turn lanes in all directions

Noise walls

When expanding a highway or realigning it with federal funds, transportation agencies are required to look into noise mitigation measures. Due to the extension of Wilbur Avenue, a study was conducted in fall 2017 to identify areas that would experience unacceptable levels of noise as a result of the project.

As a result, noise walls have been placed near Hayden Pines Mobile Plaza and  north of Haycraft Avenue/west of Carriage Court.

Depending on the location, the noise walls are up to eight feet tall, up to 20 inches wide and up to 1,000 feet long. They are made of concrete.

Shared-use path

ITD and Kootenai County finalized an agreement in March 2018 to reconstruct and to maintain a multi-use path that will extend along 19 miles of US-95 in North Idaho.

Per the agreement, ITD reconstructed approximately eight miles of the existing path along the highway from Appleway Avenue to Garwood Road using dedicated funds from the FASTLANE grant. The remaining 11 miles will be reconstructed in 2020-21 as part of the US-95 Granite North project.

Before the latest agreement, the path from Appleway Avenue to Garwood Road was not maintained and predated current state code that prevents the department from building paths without first finding local jurisdictions committed to maintaining them.

Kathleen signal damaged in crash

Following a crash that damaged the signal at Kathleen Avenue, this project will likely now incorporate the installation of a signal at that location.

Spring 2018

Noise wall added; construction extended to two years

Since the last public meeting in January 2018, noise walls and ADA improvements were added to the project. These additions, along with the process of acquiring right of way needed to add capacity at side streets, have extended the project duration from one season to two seasons.

October 2019

Sound wall completion

Curbed median installation on US-95 at Orchard Avenue and Aqua Avenue are underway.

Foundations for both sound walls are installed, and the walls are expected to be completed by the end of next week. The path is paved from Appleway Avenue to Hayden Avenue except near the sound walls.

Remaining work is planned for completion in early November and includes the following: finishing striping at Dalton Avenue, paving the remainder of the path and curbed median installation at Dakota Avenue.


The final season of work begins in earnest in April, starting with turn lane construction at Neider Avenue.
