Idaho Transportation Department seeks feedback on draft seven-year transportation plan

Roadside view of US-20 roadway and traffic west of Idaho Falls.

The Idaho Transportation Department is seeking feedback on the just-released draft Idaho Transportation Investment Program (ITIP). The ITIP outlines the state’s transportation priorities and guides investment decisions for the next seven years through 2032. ITD encourages everyone to review the draft and provide comments July 1-31.

Transportation projects included in the draft ITIP range from large-scale interstate improvements to smaller projects like the installation of new guardrail. Projects are located throughout Idaho’s 44 counties and involve all modes of transportation. Project selection is determined through technical data, as well as input from local officials and residents.

Visit itd.idaho.gov/funding to view an to learn about projects and submit a comment through the portal.

ITD Chief Deputy Director Dan McElhinney outlined, “The Idaho practice of annually updating a seven-year highway transportation plan helps consider the growth of traffic we are all seeing which is accelerating the need for safety, preservation and capacity improvements supporting communities statewide. This draft ITIP presents investment needs in highway pavement, bridge repairs, and congestion relief improvements that will provide the Idaho Transportation Board effective options to consider looking ahead for Idaho.”

In mid-June, the Idaho Transportation Board accepted staff recommendations to address congestion on priority corridors using Transportation Expansion and Congestion Mitigation funds. These funds came from House Bill 25, which was passed by the Idaho Legislature earlier this year. The legislation provides an additional $20 million a year to the TECM fund for the next three years and allows the department to invest an extra $1 billion in the Idaho transportation system.

One of the major project(s) in the draft ITIP affecting East Idaho as part of the board’s action include:

US-20 west of Idaho Falls. This project will increase capacity by widening the road to two lanes in each direction starting at Idaho Falls and moving west as funding allows. Widening will increase safety for freight, recreational and commuter traffic due to limited passing opportunities and lines of sight. Construction is anticipated start in 2026, two years earlier than planned.

Attn: Noah Ipaye
P.O. Box 7129
Boise, ID  83707

Paper copies of the ITIP will be available at regional offices and provided upon request by contacting the Idaho Transportation Department at 208-334-8284.

After approval by the Idaho Transportation Board in September, the ITIP will then be submitted to the Federal Highway Administration, the Federal Transit Administration, and the Environmental Protection Agency in October.

Public input is crucial in ensuring that the ITIP includes the prioritized needs of Idaho’s communities.

US-20 identified for further funding

Today at its regular monthly meeting the Idaho Transportation Board accepted staff recommendations on priority corridors across Idaho using TECM funds to address congestion, including several projects on U.S. Highway 20 near Idaho Falls. Since Transportation Expansion and Congestion Mitigation funds were first used by the department for bonding and advancing major projects in 2022, ITD has delivered timely construction of expansion projects across the state. Today’s actions are a continuation of that.

Funding came from House Bill 25, which was passed by the Idaho Legislature earlier this year. The legislation provides an additional $20 million a year to the Transportation Expansion and Congestion Mitigation fund for the next three years and allows the department to invest an extra $1 billion in the Idaho transportation system.

With this new funding, the following projects have been recommended for further design and construction:

US-20 west of Idaho Falls: This project will increase capacity by widening the road to two lanes in each direction starting at Idaho Falls and moving west as funding allows. Widening will increase safety for freight, recreational and commuter traffic due to limited passing opportunities and lines of sight. Construction is anticipated start in 2026, two years earlier than planned.
US-20 widening from Chester to Ashton: This project is anticipated to expand the existing roadway into a four-lane divided highway. Construction is anticipated to start in 2028.
I-15 and US-20 Interchange: This project continues to make progress toward relocating I-15 Exit 119 to US-20 and realign US-20 through Idaho Falls to address safety and congestion concerns. Funding will allow for the purchase of private property for future construction.

With these projects now included in the draft Idaho Transportation Investment Program (ITIP), the public will have the opportunity to give feedback on this project and the department’s full list of planned projects from 2026-2032 during the annual comment period in July. Then the draft ITIP will be presented to the board for approval in September.

The board’s action today reflects continued investmenttargeting congestion and capacity in major corridors that were previously funded by TECM bondsas authorized by the Idaho Legislature. In East Idaho, TECM funds allowed for the construction at the South St. Anthony Interchange, which was previously unfunded.

This project and others were identified because they are existing high-priority corridor needs that will improve traffic flow and increase safety.

US-20 Exit 320 northbound ramp into Rigby closed Monday- Wednesday, June 11

Roadway, ramp and bridge at US-20 Exit 320 South Rigby, Idaho.

Travelers can take Exit 322 (North Rigby) or Exit 318 (County Line) as detours. Those leaving Rigby to get on to US-20 will still be able to use the southbound ramp at Exit 320 toward Idaho Falls as normal.

This closure will be noted on the Idaho 511 app and at https://511.idaho.gov.

ITD Island Park foreman addresses multi-fatality crash

ITD Ashton/ Island Park foreman Ryan Wright at the site of a multi-fatality crash on US-20 near the Idaho/ Montana border.

Tragedy is, just that, tragic. The need and desire for reverence is legitimate. Difficult and hallowed situations can also cause strength, character and work ethic to shine admirably.

In sorrow for the lives lost during the crash that this article refers to, and hope that others who can relate will know they are not alone, we share the story of our role in the response.

Idaho State Police and the Idaho Transportation Department in East Idaho have a history that speaks for itself— ISP Lieutenant Marvin Crain and his troopers don’t hesitate to rely on ITD because the partnership has been proven time and time again. ITD operations and maintenance personnel across East Idaho are used to working beside ISP, ready to assist on scene as valuable first responders and traffic control.

Such was the case on the evening of Thursday, May 1, for a multiple fatality crash on US-20 at milepost 399. ITD Ashton/ Island Park foreman Ryan Wright has been in his role for the past 15 years and is an integral part of the small communities he serves. He heard about the incident just after it happened. Knowing it was blocking both north and southbound lanes, he sent his Island Park crew to direct traffic before ISP ever called. Wright then got in his own truck and headed to the scene personally.

“I don’t know what frame of mind a guy goes into it with. I can’t say you get used to it because you don’t,” Wright emphasized. “It’s just something we have to do. I guess it’s just work mode.” He said he tries to keep his crew members from having to be right in the thick of things during crash responses.

Once there, ISP spoke with Wright to request an additional flagger farther south. An Ashton crew member was called and showed up to fill that role. Wright himself pitched in to help however he could, knowing the Fremont County Coroner personally and working alongside the familiar ISP folks involved.

Wright and his crew members were on scene and assisting until the crash was cleared around 2 a.m.

“It’s when you get home and the adrenaline goes down and you start thinking,” Wright said. “The visions in your head you just don’t get rid of.”

East Idaho ITD leadership and Safety Officer Ronnie Butler made contact personally to get CISM, the Critical Incident Stress Management team that exists in each ITD district, available and ready for Wright and his crew. The individuals who are part of a CISM team are trained to offer a listening ear, help manage expectations after a traumatic event, and connect employees to the services needed. Each member is interviewed before joining the team and has related experience of their own.

“I’m not sure why I’ve always been able to handle it because I’ve seen some terrible wrecks,” Wright added. “We each deal with stuff our own way. I’ll usually call another foreman. We have each other.”

In the time since the crash, Wright has had to re-visit the site to assess damage and determine what needs done to ensure the continued integrity of US-20 near the Montana border. This road is the connection to the western entrance of Yellowstone National Park. ITD crews will conduct mastic and grader operations in the coming weeks as soon as investigations allow.

To our ITD operations and maintenance crews across the state, your contributions as first responders and the ones who pitch in during traumatic incidents do not go un-noticed. Thank you for your strength—you are appreciated and of such great worth.

Resources will always be available to help after an incident. Any ITD employee struggling as a result of work or on a personal level, don’t hesitate to contact your CISM representatives—they are happy to help and located to be able to respond immediately. You are not alone.

East Idaho travelers will see even more improvements to US-20

RIGBY—Exploratory drilling along U.S. Highway 20 from Idaho Falls to Rigby, as well as pavement replacement within the active roadway north of Rexburg, begins Monday. The Idaho Transportation Department is urging travelers to be aware of equipment and crews through these particularly busy areas.

“Last year, we had three near miss occurrences as we were drilling on US-20 near Idaho Falls,” ITD Geologist Shawn Enright said. “We want people to be particularly aware so we can make sure everyone gets home at night and the work gets done too.”

Over the next three weeks, contractor partners will have drill rigs and traffic control in operation near the ramps, overpasses and canal crossings from Interstate 15 Exit 119 in Idaho Falls to Rigby to gather data for potential future widening of US-20. Work will happen within the shoulder or roadside.

More efforts to improve US-20 from North Rexburg Exit 337 to Driggs/ Jackson Exit 339 are also beginning Monday and will continue throughout the next three weeks. Contractor partners will be repairing the worst sections of roadway to provide a smoother ride for motorists.

The northbound ramp to access US-20 at Exit 337 will be closed through the day on Tuesday, April 29. Once work has progressed north, motorists will see closures of the northbound on-ramps at Sugar City/ Salem Exit 338 and Driggs/ Jackson Exit 339. Each closure is expected to last no more than a few days and will only remain through daytime hours.

This work will be noted on the Idaho 511 app and 511.idaho.gov. Drive aware and drive safe while crews make Idaho’s roads better.

Look out for crews and traffic control as spring road work begins across East Idaho

ITD crews perform crack sealing repairs on I-15. Men are wearing hi-vis yellow and operating handheld equipment at the back of a small crack sealing trailer.

RIGBY— With the onset of spring, over the next several months the Idaho Transportation Department and contractor partners are crack sealing, repairing potholes, removing hazardous trees and conducting more substantial improvements to ruts and bumps in the roads from Salmon to Driggs and the Montana state lines to Idaho Falls.

Crack sealing is underway on Interstate 15 from Idaho Falls to Dubois, as well as State Highways 33 and 47. This work involves a mobile one-lane restriction that follows workers’ progress. ITD crews fill minor cracks in the roadway with a strong, sticky tar that serves to keep water from getting under the surface and making the damage worse. This must be done in spring during cooler temperatures and dry conditions, and then the repair effectively expands through warmer months.

Flagging operations will be in place temporarily on state highways across east Idaho as ITD performs mastic pothole repair. Expect flagging delays to be less than 15 minutes where this work is occurring. Mastic work uses a hot-applied rubber and asphalt combination that is highly effective at sealing up more substantial damages in the road. These fixes must also be done in dry conditions and specific temperatures seen during the spring. Crews time work before or after peak travel times, even at night as needed.

On U.S. Highway 20 between Rexburg and St. Anthony, crews will be working to mill off the surface of the road in 1,500-foot stretches or less and then overlay new pavement. Expect to see one lane closures and speed reductions where this is occurring.

Hazardous tree removal will also begin this spring on U.S. Highway 93 between Challis and Salmon. ITD crews can sometimes work off the roadway, though flaggers will be in place as needed, with one lane restricted in 15-minute increments. The removal of dying and diseased trees will improve errant driver safety recovery zones, wildlife visibility and fire protection widths. This effort will continue through the spring and into the summer months.

Other routine spring maintenance work like shoulder repairs and delineation enhancements are also ongoing. Drivers should be aware of these smaller work zones, slow down and move over to help everyone stay safe.

Final full closure for US-20 Rexburg interchange starts tomorrow

US-20 Exit 333 at Rexburg, road closed sign in place with construction equipment surrounding

U.S. Highway 20 Exit 333 for Main Street in Rexburg will fully close beginning tomorrow. This closure allows crews to complete final paving operations and marks the last time Rexburg exits are expected to close for the construction of new diverging diamond interchanges. Exit 333 will be re-opened as soon as paving and striping work is finished, on or before October 29.

“Our goal was to have these projects completed by late fall and that really is going to happen,” Project Manager Conner Huffaker said. “We’re so grateful to the Rexburg community for their support and patience.”

After re-opening, construction efforts at Exit 333 will be largely off the roadway, with only limited lane closures from that point on. Motorists can expect some interruptions as work continues toward final completion, though they will be short lived.

With construction efforts winding down, motorists will also see improvements to timing for the traffic signals at both Exits 332 and 333. Engineers will make signal adjustments until the movement of the new interchanges is ideal for typical traffic flow.

Since March, the Idaho Transportation Department and contractor partners have been working to complete the massive undertaking of rebuilding Exits 332 and 333 in Rexburg. Both exits are now operating diverging diamond interchanges that are expected to resolve former traffic concerns in the Rexburg area.

Pavement repairs begin across eastern Idaho this summer

Pavement improvements on east Idaho road

The Idaho Transportation Department is utilizing the summer window of opportunity to resurface and repair several roadways across eastern Idaho. Pavement overlays and repairs increase the strength and longevity of our roads, helping them to better withstand the weather conditions in this region. Beginning mid-July, motorists can expect to see traffic limited to one lane as needed in the following work zones:

Interstate 15, milepost 112 at Bingham County line to Exit 119 at U.S. Highway 20 Interchange. Work in this area through Idaho Falls will be conducted at night from 8 p.m. to 6:30 a.m. Traffic will be limited to one lane intermittently in both directions where crews are actively working. Work is expected to last approximately three weeks.

I-15 Exit 119 to Exit 143 at Sage Junction. Traffic will also be limited to one lane intermittently in both directions where crews are actively working. Work on this section of the interstate will be conducted during daytime hours and last until mid-October.

US-20 from milepost 264 at Bonneville County line to milepost 301 at the Idaho National Laboratory junction. Beginning mid-July, patch and repair work will be underway, with flaggers and one-lane closures in the working area. This section of road will also undergo a seal coat later in August. Work is expected to be complete by mid-August.

State Highway 28 milepost 101 at Lemhi River Bridge to milepost 125 at Baker, and milepost 305 to 306 on SH-93 in Salmon. These pavement projects require that a mobile hot mix plant be set up closer to the area of work so asphalt temperatures can be kept where they need to be to correctly build the road. This operation entails equipment parts and pieces being hauled with large transport trucks and then constructed at the Leadore state gravel pit. Once the plant is set up and operational, work is anticipated to last approximately eight weeks. Expect one-lane closures along SH-28 with pilot cars and flaggers in place.

SH-93 milepost 108 at Mackay to milepost 115 at Mackay Reservoir, and milepost 139 at Willow Creek Summit to SH-75 junction. Traffic will be limited to one lane intermittently using pilot cars and flaggers in the current working area. Both lanes will be open again overnight. Work is expected to begin late July and last until mid-September.

US-26 northeast of Craters of the Moon visitor center from milepost 230- 240. This section of road will be dug out and replaced with new pavement. Pilot cars and flaggers will direct traffic through one lane. Work is expected to be complete in just six days, beginning in early August.

Remember to use caution and stay alert when traveling through work zones. Up-to-date information on these projects is available by visiting 511.idaho.gov, dialing 5-1-1, or downloading the 511 app.

US-20 Exit 332 in Rexburg to fully close Wednesday, May 29 for construction

Exit 332 on U.S. Highway 20 in Rexburg will completely close for one month beginning next Wednesday, May 29 to allow crews to quickly build a new unique diverging diamond interchange (DDI) that will greatly improve the flow of traffic.

All ramps at this exit and University Boulevard between the ramps will be closed to traffic and detoured to nearby interchanges. Through traffic on US-20 will be unaffected during construction.

Detours include Exit 328 at Thorton and Main Street Exit 333 in Rexburg. A temporary signal has been set up at Exit 333 to accommodate additional traffic. Access to businesses near Exit 332 will remain open with signage in place to direct drivers.

“Closing the exit allows crews to work at a significantly faster rate. Our goal is to have this interchange reopened before the Fourth of July,” Resident Engineer and Project Manager Conner Huffaker said.

Motorists should use caution and be aware of congestion. Crews will coordinate with emergency responders to ensure access through the closed construction zone when needed.

Once Exit 332 is reopened, work to construct the same DDI design at Exit 333 will begin. The closure of Exit 333 is expected to begin late July or early August.
