Public invited to open houses to comment on preliminary I-90 corridor designs

Traffic congestion I-90 near Huetter

ITD will host two open houses next week in Post Falls and Coeur d’Alene to present recommended designs to improve I-90 between the Washington state line and Sherman Avenue in Coeur d’Alene. The ongoing study is funded by the Leading Idaho program.

Each open house will present identical information and designs.

Post Falls

  • Tuesday, Nov. 1
  • 4 p.m. – 7 p.m.
  • Red Lion Hotel Templin’s on the River at 414 E 1st Ave

Coeur d’Alene

  • Wednesday, Nov. 2
  • 4 p.m. – 7 p.m.
  • Best Western Plus Coeur d’Alene Inn at 506 West Appleway Ave

For those not able to attend either open house, an online option will share the same information and will be available on Nov. 1 at

“Since the first stretch of I-90 was built in Kootenai County in 1960, ITD has made some upgrades, but the number of lanes has not changed,” said Erika Bowen, ITD Project Manager. “With traffic currently congested in various parts of the corridor and volumes expected to double by 2045, ITD is studying the interstate to identify improvements to modernize the system, reduce crashes and save drivers time.”

Proposed improvements include adding lanes on I-90, modifying access and upgrading interchanges with impacts to local roads in both cities. Areas with proposed improvements include:

  • Spokane Street and Seltice Way Interchanges
  • Northwest Boulevard Interchange
  • US-95 and Fourth Street Interchanges
  • Seventh Street Bridge
  • Sherman Avenue Interchange

Following the study and public input, the recommended projects will be prioritized and advanced into design and construction as funding becomes available.

The study is funded with Transportation Expansion and Congestion Mitigation (TECM) funds 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.

The corridor is one of 13 approved TECM corridors in the state. Funding for the future design and construction phases on this corridor will be determined based on project readiness and funding availability. Preliminary estimates value the improvements needed in this corridor at $1 billion to $1.2 billion, which includes design, right-of-way and construction costs. A previously funded project to redesign the SH-41 interchange at I-90 is currently under construction.

ITD shares future plans for State Highway 55 and I-84, Karcher Interchange at Nampa open house July 7

The Idaho Transportation Department (ITD) invites the public to an open house this month for two adjacent projects in Canyon County. Design plans will be shared for improvements to the Interstate 84, Karcher Interchange and several miles of State Highway 55 west of the interchange.

Community members may stop by an in-person open house on Thursday, July 7 between 5 and 7 p.m. at Nampa Christian School, 11920 W. Flamingo Avenue in Nampa. Online open houses for each project will also be available July 7-14 at and

“These two projects are part of ITD’s ongoing work to address growth and the resulting congestion on highways in Canyon County, particularly State Highway 55,” said project manager Erika Bowen. “ITD is targeting the most urgent needs in this area while continuing to plan for long-term solutions.”

The I-84, Karcher Interchange project includes widening the interchange bridge and adding a new westbound lane across the interchange to Caldwell Boulevard. Several improvements are also planned on the interchange ramps, signals, and intersections. Details are available at

The SH-55, Farmway Road to Middleton Road project will widen SH-55 to two lanes in each direction in the busy area between Farmway and Middleton roads. More information is on the project website at

Once construction funding has been confirmed, work on the Karcher Interchange could begin as early as 2023, and the widening of SH-55 could start in 2024.

Funding for this design stage of both projects comes from the Leading Idaho Transportation Expansion and Congestion Mitigation Program. The program allows ITD to build critical infrastructure today that would otherwise take many years to build.

ITD launches two-week virtual meeting (May 21-June 4) to share next steps for Idaho 16 extension

Idaho Highway 16 in the Treasure Valley

The Idaho Transportation Department launches a two-week online meeting today (May 21) to share plans for the next phase of extending Idaho Highway 16 through the central Treasure Valley. The meeting will be available from May 21 to June 4 at

The meeting includes a virtual tour and design plans for the future north-south corridor, which is currently the primary route to Emmett. ITD is extending the corridor 5.5 miles south to connect with I-84.

Online Public Meeting Invite

The extension of Idaho 16 will operate as a high-speed expressway, with limited access on or off it. By 2040, the highway is expected to serve 60,000 motorists each day in the growing area between Ada and Canyon counties.

“This corridor has been in the making for many years and the community has given input at many important stages of this significant highway corridor,” said ITD Program Manager Amy Schroeder. “All of the design plans in this online meeting are consistent with the overall vision and allows ITD to proceed to construction next year.”

Phase 1 of the corridor was completed in 2014 and involved bridging Idaho 16 over the Boise River and connecting U.S. 20/26 and Idaho 44.

On Wednesday, the Idaho Transportation Board approved funding to construct the next phase of the extension. Phase 2, the focus of the online meeting, will build the remaining five miles of highway from U.S. 20/26 to I-84. This includes an interchange with I-84, connections at Franklin and Ustick Roads, and bridge structures over local roads, canals, and a railroad.

The estimated cost of this work is $170 million. It will be funded using bonds and paid off using new sales tax funds approved by the Idaho Legislature in 2021.

“The work we have done on the Idaho 16 corridor in the last few years has prepared us to quickly leverage this new funding stream,” said Schroeder. “We have an obligation to the taxpayer to make the most of the today’s low interest rates and bring needed transportation investments to Idaho quickly.”

The online meeting will include live Q&A sessions from 12-1 p.m. and 5:30-6:30 p.m. on June 2. Alternate versions of the meeting are available for those without Internet access. Please contact ITD at (208) 334-8008 or
