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.
- Middleton Rd
- Midland Blvd
- Northside Blvd
- N Franklin Blvd
- 11th Ave N

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.
