Chinden West US-20/26 — Middleton Rd to Star Rd Project

Skip to main content

Welcome

Hello and thank you for your interest in the Chinden West US-20/26, Middleton Road to Star Road project. The purpose of this online meeting is to provide information about design plans to improve roughly six miles of US-20/26 from Middleton Road to Star Road.

Thank you again for taking the time to learn more about this important project.

Project Background

In 2017, the Idaho Transportation Department (ITD) completed the US-20/26 Corridor Study from I-84 to Eagle Road. The study identified needed long-term improvements including the following:

  • Six travel lanes (three in each direction)
  • A raised island median to separate eastbound and westbound traffic
  • Improved roadway shoulders
  • A 10-foot detached shared-use path for pedestrians and cyclists
  • Signalized intersections

To advance improvements and maximize existing funding, ITD set an interim goal of widening the corridor to four lanes from I-84 to Eagle Road.

Chinden West US-20/26 Middleton Road to Star Road

Construction of the Middleton Road to Star Road segment will complete ITD's interim goal of widening the corridor to four lanes from I-84 to Eagle Road.

These improvements should reduce the number of crashes and relieve congestion.

Middleton Road to Star Road Improvements

Interim improvements will widen the road to four travel lanes (two in each direction), create a median, and make shoulder improvements. The project will also replace existing canal crossings, construct signalized intersections at each mile, improve drainage, and add a shared-use path.

Ultimately, this project will widen the roadway to six lanes.

Intersection Improvements

ITD plans to improve and signalize six intersections within the corridor at Middleton Road, Midland Boulevard, Northside Boulevard, Franklin Boulevard, 11th Avenue, and N Can Ada Road.

Intersection Configurations

ITD is working with local agencies to coordinate future US-20/26 connections to local roads. The design currently shown may change as a result.

What Has Changed Since 2017?

The Environmental Assessment completed in 2017 identified a few design features that will NOT be implemented, including the folowing:

Cul-de-sacs at Knott Lane, Madison Road and Prescott Lane

Instead ITD will construct right turn lanes for deceleration at these locations. These intersections will also be limited to Right In/Right Out configurations for both the interim and ultimate designs.

Half or full Continuous Flow Intersections (CFI) will not be included in the interim project

ITD will construct improved signalized intersections at Midland Boulevard, Northside Boulevard, Franklin Boulevard, 11th Avenue, and N Can-Ada Road.
