Graphic map showing I-84 interchange with local road. The area of I-84 over the road is highlighted indicating the construction area.

The Idaho Transportation Department will close Gowen Road nightly beginning Friday as part of a bridge repair project on Interstate 84. These closures are needed to facilitate safe and efficient traffic flow while both eastbound lanes of I-84 are closed at the Gowen Interchange. This project will repair bumps in the roadway caused by settling and rutting at the beginning and end of the bridge.

Road closure schedule:

Saturday and Sunday nights: 7 p.m. to 7 a.m.
Monday through Friday nights: 7 p.m. to 5 a.m.

Detour routes:

From Gowen Road to I-84 (eastbound or westbound):

Turn right on Eisenman Road, proceed to the Eisenman Interchange, and use on-ramps to access I-84 in either direction.

From Gowen Road to SH-21 or Federal Way:

Turn right on Eisenman Road, proceed to the Eisenman Interchange, access I-84 westbound, exit at the Gowen Interchange, and follow signs to SH-21/Federal Way.

From SH-21/Federal Way to eastbound I-84 or Gowen Road:

Travel east on Federal Way to the Eisenman Interchange. From there, access I-84 westbound or turn west on Eisenman to return to Gowen.

These closures coincide with previously released nightly full closures of eastbound I-84 near the Gowen Interchange. During the closures, eastbound drivers will be detoured off I-84 at the Gowen Road off-ramp and directed back onto the interstate via the on-ramp. The detour will remain within the same interchange, and only minor delays are expected.

Drivers are encouraged to plan ahead, follow posted detour signs, and allow extra time when traveling through the area. For the latest updates and traffic conditions, visit 511.idaho.gov or use the Idaho 511 app.

How ITD teamwork and ingenuity delivered a safer intersection

When traffic starts backing up at the Banks-Lowman and SH-55 intersection in SW Idaho, especially during the busy summer months, locals feel it and so do ITD crews. For years, temporary flagging operations helped keep things moving, but concerns continued to build around congestion, public safety, and the risks faced by flaggers working in live traffic.

So, District 3 Operations took action. Without dedicated funding but with a deep understanding of the need, the department made a bold decision: build and install a traffic signal in-house.

It was the first time ITD crews had taken on a signal project from start to finish, including design, construction, and installation, and they pulled it off in just 15 months. A similar project delivered through the traditional method would have taken 3-5 years and cost around $1.5 million. By handling it internally, ITD completed the work for under $500,000.

“The crews’ efforts, communication, and coordination were exceptional,” Nestor Fernandez, District 3 Operations Engineer, said. “Each team, whether from our own district or assisting districts, was fully committed and invested in completing their tasks. The seamless collaboration across groups ensured work was completed efficiently and to a high standard.”

That creativity was especially important when it came to phasing the new signal. The intersection didn’t have existing turn lanes, and a single-lane bridge had to be managed without introducing excessive delay. Because the design was handled in-house, the team could think outside the box and the result was a tailored solution that worked.

While some highly specialized elements, like foundation drilling and pole installation, were contracted out, the majority of the project was delivered using state forces. ITD teams from across the agency contributed, and that statewide collaboration proved to be a game-changer.

From navigating environmental requirements to expediting material procurement, every step of the process came with a learning curve. But the result wasn’t just a safer intersection, it was a powerful example of what’s possible when teams work together and think creatively.

“Constructing this project with state forces was a unique and valuable experience for the district,” Nestor added. “The positive, seamless collaboration and communication across all sections, and with the contractors, was a key factor in its success, as was the strong ownership each team took in their role.”

The Banks-Lowman signal project has already made a difference for local residents and travelers alike.

Justin Smith wins Award of Excellence for history series

The hits keep on comin’ for District 5 Public Information Officer Justin Smith, who just last month won an Esto Perpetua award from the State Historical Society for his outstanding work promoting and preserving Idaho history. Last week, Smith won an Award of Excellence from the communications group APEX for the series of Transporter articles detailing the early transportation history in the state.

“Idaho has a rich transportation history stretching from the old Indian footpaths and the Oregon Trail to today’s highways and freeways,” said Smith. “In many ways, transportation history is the history of Idaho. I love our state and am passionate about its past and its people. I’m especially grateful for my job at ITD where I have the opportunity to share in telling ITD’s past as well as work with the many people who are continuing the proud transportation tradition!”

Smith has published a dozen “Early Transportation in Idaho” articles so far.

“I love the stories that Justin shares with us about Idaho transportation history,” said Office of Communication Manager John Tomlinson. “This is just one of the awards he has won for his historical writing this year. His passion for preserving Idaho history benefits us all.”

Blackfoot maintenance shed’s open floor design improves safety

The newly remodeled Blackfoot shed sports a new floor, drains, windows, paint, electrical, and fire suppression, but what really gets foreman Troy Despain excited is the wide-open shop space.

Before the remodel the shed was a tight proposition. Plows backed into their slots with barely inches to spare in front of and behind the vehicles. In addition, there were ceiling support posts that drivers had to gingerly navigate around. One wrong move backing into the shed and thousands of dollars could be lost

Today the shed looks brand new. The depth of the building has been expanded to allow more room in front of and behind the plows. In addition, Despain pushed hard for an open floorplan without the original design’s support posts. “We build spans across gorges, there’s no reason why we couldn’t put in a large beam that removed the necessity of those support pillars.”

While there are a few support posts at the ends and joints between beams, a massive steel beam carries the roof’s weight over the majority of the shop resulting in an open shop floor and improved safety. Despain says the new main beam design will be the standard moving forward for other sheds. “It just makes sense,” he said.

Public invited to review findings and proposed improvements for SH-44 corridor

Community invited to learn about Highway 16 and 44 improvement projects.

The Idaho Transportation Department invites the public to attend two upcoming open houses to learn about findings and recommended improvements for the State Highway 44 corridor between Interstate 84 and Star Road.

SH-44 is a key east-west route through Middleton and Star. With continued population growth, traffic volumes and congestion have increased and reinforced the need for a modernized SH-44. This project proposes alternatives to realign SH-44.

These open houses will give the public an opportunity to review the results of the alternatives evaluation and see which proposed recommendations advance into preliminary design and environmental review.

Open house details:

Tuesday, Aug. 26

Middleton Middle School, 511 W Main Street, Middleton

4:30 p.m. – 7 p.m. (drop in anytime)

Wednesday, Aug. 27

Star Fire Protection District, 11665 W State Street, Ste. B, Star

4:30 p.m. – 7 p.m. (drop in anytime)

The same materials will be available online from Aug. 26 through Sept. 10 at itdprojects.idaho.gov/pages/sh44pel.

“We’ve spent the past two years working with agency partners and local communities to identify practical solutions for this growing corridor,” ITD Project Manager Mark Wasdahl said. “This is the public’s chance to see the alternatives we evaluated and what we’re recommending to move forward.”

This study followed the Planning and Environmental Linkages (PEL) process to identify and screen potential transportation improvements. The PEL process is a collaborative approach to decision-making for transportation projects. Used to gather data and input from the community and stakeholders, PEL helps to understand a project’s needs and goals and identify solutions before moving into the detailed analyses required by the National Environmental Policy Act. The project team previously held three rounds of open houses in January, April, and September 2024 to gather feedback from the public.

Construction for this project has not yet been funded.

Nighttime closures planned for eastbound I-84 near Gowen Road

Starting Friday, the Idaho Transportation Department will begin one week of nighttime closures on eastbound Interstate 84 near Gowen Road. The closures are part of a repair project to fix bumps in the roadway caused by settling and rutting at the beginning and end of the bridge.

During the closures, eastbound drivers will be detoured off I-84 at the Gowen Road off-ramp and directed back onto the interstate via the on-ramp. The detour will remain within the same interchange, and only minor delays are expected.

The project involves reconstructing approximately 250 feet of the two-lane eastbound approach before the Gowen Bridge, as well as 50 feet beyond it.

Full eastbound closures are scheduled during the following hours, weather permitting:

Monday through Friday: 7 p.m. to 4 a.m.
Saturday and Sunday: 7 p.m. to 7 a.m.

Drivers are encouraged to plan ahead and allow extra time when traveling through the area. For the latest construction updates and detour information, visit 511.idaho.gov or use the Idaho 511 app.

Idaho’s historic highway markers get a modern makeover

Travelers along Idaho’s roads and scenic byways will soon see the first of the new Idaho Historic Highway Markers. These refreshed signs combine storytelling with modern technology, offering visitors a more immersive experience and a stronger connection to the communities they pass through.

The initiative combines two projects across three state agencies. The Idaho Transportation Department and Idaho State Historical Society are partnering to update all highway markers with new historical research and signage. In tandem with these efforts, Visit Idaho is developing QR codes to be installed at each marker location, connecting travelers to an app that offers additional content about the site and nearby activities and amenities. The app will also translate to nine other languages. The digital component is funded in part by a $3.2 million federal economic development grant awarded to ITD in 2022.

The goal is to restore the historic markers to spark curiosity about the state’s expansive history and drive interaction with the app to encourage exploration of Idaho’s rural communities, helping increase overnight stays and drive economic impact across Idaho.

“This project aligns perfectly with many of the initiatives Visit Idaho is focused on. Idaho’s diverse and often rural landscape is filled with communities that we know travelers will enjoy once they go beyond the destinations they already know. We’re excited to incorporate the QR codes as an easy, accessible tool to help travelers find more to explore in our beautiful state,” said Natalie Jushinski, tourism manager at Visit Idaho.

Each of the three state agencies plays a distinct role in this multi-year project:

ITD owns and maintains the physical markers and is managing the installation and updated marker designs, which now feature state symbols like the mountain bluebird and the syringa.
Visit Idaho, a division of the Idaho Department of Commerce, is developing the QR codes and web-based app connecting travelers to information to explore more in the area.
ISHS is responsible for the historical content for the markers, and their historians are updating the text on each marker to amplify understanding of the significance of each site.

The project not only enhances the travel experience but also supports rural tourism and local economies by encouraging deeper exploration. The revitalized markers and digital information provide new opportunities for education, storytelling and visitor engagement for all travelers—both residents and visitors.

“We are grateful to be a part of the Historical Highway Marker program, which continues to create a powerful sense of place for Idahoans. These markers share the stories that make the Gem State truly unique — stories that have been updated and thoroughly researched at a local level, deepening our understanding of Idaho’s vibrant history,” said Janet Gallimore, executive director at ISHS. “They remind us of where we’ve been, connect us to one another, and strengthen the sense of community that defines our state.”

All updated markers and QR codes in ITD’s District 1 in North Idaho are expected to be installed by the end of 2025, with no impact on traffic. The remaining markers and QR codes will be installed in phases by district through 2027.

“We are excited to partner with others to ensure that these roadside displays reflect the beauty and rich history of Idaho,” said Mike Johnson, the division administrator for engineering services at ITD.
