ChindenWest Corridor (U.S. 20/26) construction starts fall 2019

BOISE – Much of U.S. 20/26 between Eagle Road and I-84 will be under construction starting this Fall and lasting for several years.

The corridor, dubbed ChindenWest, is a vital east-west corridor in the heart of the Treasure Valley. Explosive growth in west Boise and Meridian and increased demand on the two-lane highway. The construction will add travel lanes, widen shoulders, and build a separated path parallel to the roadway.

Starting this fall and continuing for several years, construction will be underway from Eagle Road to Star Road. Additional construction is scheduled on the western edge of the corridor, from I-84 to Middleton Road beginning in late 2021. ITD is pursuing additional funding to continue construction throughout the corridor.

Ahead of construction, ITD has relaunched the project website at ITDprojects.org/ChindenWest, which will serve as a hub of information for the public. Several segments of the ChindenWest Corridor will be under construction at different times and by different contractors. The one-stop-shop website includes detailed information about project development, anticipated traffic impacts, and the improvement designs.

“We’re excited to launch this construction,” said ITD Construction Engineering Manager Jason Brinkman. “It’s been years in the making, with extensive environmental evaluation, design, and public involvement. The need is now and when the work is done, the safety, mobility, and economic opportunity of the area will be improved.”

Here’s a breakdown of the different segments of the ChindenWest Corridor and when construction is anticipated to begin:

ITD will host an open house in the area ahead of construction this Fall to inform the public about impacts.
