I-84

What's next for I-84 in Caldwell?

The Idaho Transportation Department is moving forward with plans for expanding I-84 in Caldwell. Future projects include:

• Final design of improvements between the Centennial Way and Franklin Road interchanges in Caldwell (exits 27-29).
• An environmental study for future expansion between the Idaho 44 and Centennial Way interchanges at the western edge of Caldwell (exits 25-27).

Both projects are funded through Idaho Governor Brad Little’s “Leading Idaho” transportation funding solution. Funding for construction will be identified in future years.

Background

I-84 is the main commuter and freight corridor through the Treasure Valley and southern Idaho.

Over the last five years, ITD made major improvements to I-84 in Nampa and eastern Caldwell. These improvements are expected to be completed in 2023.

In 2018, ITD completed an environmental study of future I-84 improvements as far west as Centennial Way. Only part of these improvements were funded initially.

In 2021, the Idaho Legislature approved the Leading Idaho transportation funding solution to fund critical infrastructure improvements throughout the state. Through this program, ITD will continue the expansion of I-84 through Caldwell.
