The Idaho Transportation Department (ITD) will host an open house next week in Post Falls to present two design alternatives for the Post Falls area as part of the I-90 corridor study. Preliminary design alternatives include options to increase capacity and mobility in the Post Falls area, while modernizing the interstate’s infrastructure that was originally built in the 1960s and 1970s.

Open House Details

Date: Thursday, October 5

Time: 4 p.m. – 7 p.m.

Location: The Jacklin Arts & Cultural Center

405 N William St, Post Falls, ID 83854

“ITD received valuable feedback from the public and area stakeholders at our first open house last year. Our team has integrated that feedback into two modified alternative designs that use different approaches to improve congestion, mobility, and safety,” ITD Project Manager Erika Bowen said. “Our goal is to connect with the citizens of Post Falls to discuss these revised options and gather feedback on which alternative or features of the alternatives best improves travel for residents and businesses alike.”

The open house will feature two design alternatives adapted from the designs previously shared for public feedback in November 2022. Feedback collected in this round of public engagement will be used for an ongoing update to the master transportation plan for the city of Post Falls. Until additional funding is identified to complete the remaining analysis from Washington state line to State Highway 41, the corridor study through the Post Falls area will be on hold.

For those not able to attend the open house, an online option will share the same information and be available on October 5 at Comments submitted online before October 19 will be considered by the project team.

The I-90 corridor study is funded as part of Governor Little’s Leading Idaho initiative. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build. Preliminary estimates value the improvements needed for I-90 between Washington state line and Coeur d’Alene at nearly $1 billion, which includes design, right of way and construction costs.
