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.

A Spanish interpreter will be present at the July 7 open house. Community members can also request written materials in Spanish by calling (208) 334-8002.

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

ITD considering partnership to reinitiate maintenance of backcountry airstrip in Lemhi County

Hoodoo Meadows Airstrip corridor and borrow trench - Photo taken near entrance facing North.

The Idaho Transportation Department’s Division of Aeronautics (ITD) is seeking public comments as it considers restoring and managing a backcountry airstrip in the Salmon-Challis National Forest.

The Hoodoo Meadows airstrip (as shown in image above) is the highest in the state at an elevation of 8,200 feet, and provides access to the Frank Church – Wilderness of No Return. The airstrip is located just south of Yellowjacket Lake and near the popular Bighorn Crags area. It has not been used since the 1980s.

The site was managed by the U.S. Forest Service (USFS) after its construction in 1936 by the Civilian Conservation Corps, and traditionally used to gain recreational access for alpine lake fishing, wildlife viewing, and big game hunting. Although there were no reported accidents, in the early 1980s the airstrip was rated marginal for safety, and by 1989 trees had encroached the site and made it unusable.

In 2016, the Idaho Department of Fish and Game (IDFG) initiated the effort to restore the Hoodoo Meadows airstrip, due to repeated public inquiries about recreational accessibility. Together, USFS, IDFG, and ITD, with support from the Idaho Aviation Association and the Recreation Aviation Foundation, are working on an agreement that would open the site for air travel and provide for future maintenance.

“This effort has been underway for several years. Our role would be making the airstrip safe for pilots to land again, by clearing vegetation and installing safety features like runway markers,” Aeronautics Administrator Jeff Marker said. “It would take about a month of initial cleanup work on our part, but would provide more access for those who wish to explore some of the most remote places in Idaho.”

Visit to review the proposed partnership, then please provide ITD your feedback on the plan. Public comments will be accepted March 15 to March 29 through the following options:

  • Email
  • Record verbal testimony by calling (855) 785-2499
  • Send your written comments by mail to
    ATTN: Jillian Garrigues
    Idaho Transportation Department
    PO Box 7129
    Boise, ID 83707

The USFS sought comments in 2018 on reopening the Hoodoo Meadows airstrip. Now, the public can voice their support or concerns regarding ITD’s involvement in the partnership.
