Idaho drivers should expect delays beginning Wednesday near Homedale, as the Idaho Transportation Department (ITD) will apply a sealcoat to five miles of State Highway 19. This project will extend the life of the roadway.
SH-19 from the Oregon border to the U.S. Highway 95 Junction in Homedale will be reduced to one lane in the direct area crews are working, with the lane closure moving as work progresses. Vehicles parked along the route will need to be moved prior to work beginning.
Flaggers and a pilot car will help guide traffic through the project area. To minimize traffic disruptions, work will be limited to weekdays from Monday through Thursday. The project is expected to be completed in August.
It’s important for motorists to plan ahead this summer by checking traffic impacts on their route at 511.idaho.gov.
The eastbound on-ramp and off-ramp on Interstate 84 at the Simco Road Interchange (Exit 74) will be closed for construction beginning Monday and will not reopen until late August. Vehicles using these ramps will be rerouted through Mayfield (Exit 71). This closure is necessary in order for crews to pave and stripe the new ramps.
The Simco Road Bridge over the freeway will remain open as one lane. Drivers can expect reduced speeds when approaching the interchange.
Construction began in July 2023 to replace the bridge over I-84, originally built in 1959. Work is expected to be completed this fall.
The Idaho Transportation Department reminds drivers to be patient, slow down and obey all posted signs in the construction zone. Travelers should check 511.idaho.gov before driving in the area.
The eastbound on-ramp and off-ramp on I-84 at the Simco Road Interchange (Exit 74) will be closed for construction starting Monday and will not reopen until late August.
The Idaho Transportation Department advises motorists to plan for nighttime Interstate 84 eastbound and westbound closures on Monday and Tuesday between the Garrity Boulevard and Ten Mile Road interchanges (Exits 38 and 42).
Crews are stripping framework and installing overhead sign foundations at the future interchange of State Highway 16 and I-84. One direction of I-84 will be closed each night during this work.
July 8:
Westbound I-84 will be closed between the Ten Mile (Exit 42) and Garrity (Exit 38) interchanges from 10 p.m. Monday night to 6 a.m. Tuesday morning. Click here for the detour map.
July 9:
Eastbound I-84 will be closed between the same interchanges from 9 p.m. Tuesday night to 5 a.m. Wednesday morning. Click here for the detour map.
The speed limit will be reduced to 45 mph at night.
University Boulevard Exit 332 in Rexburg will re-open by Wednesday morning. The exit has been closed since May 29 to allow the Idaho Transportation Department and contractor partners to efficiently construct a diverging diamond interchange (DDI) that will improve traffic flow and safety.
Motorists should be aware that work to finish construction at Exit 332 will be ongoing until mid-October. Paving, striping, infrastructure, and beautification efforts will create the need for occasional lane closures. One lane of traffic in each direction will remain open during these instances.
With Exit 332 re-opened, Rexburg Main Street Exit 333 will be fully closed beginning in late July so the same DDI traffic flow can be built there. More information about that closure will follow in the future.

Idaho drivers are urged to plan ahead when traveling north of Eagle this summer as the Idaho Transportation Department (ITD) is advancing several projects along State Highway 55. These projects include lane closures and reduced speeds in various locations between Eagle and New Meadows.
“Each of these projects is intended to improve traffic flow and safety along this regional route. We look forward to a safer, smoother State Highway 55 after these projects are complete,” District 3 Engineer Jason Brinkman said.
The projects include:
Little Goose Creek Bridge (Construction: June 2024 – late 2024)
ITD will begin replacing the Little Goose Creek Bridge today along SH-55 near Last Chance Campground in New Meadows. SH-55 will be reduced to one lane in the area with flaggers and a traffic signal during construction. Drivers should expect delays. Learn more and sign up for construction updates on the project website.
SH-55 Smiths Ferry to New Meadows chip seal (Construction: July 2024 – fall 2024)
This July ITD will start applying a chip seal to several areas of SH-55 between Smiths Ferry and New Meadows. This project will extend the life of the pavement. The highway will be reduced to one lane with pilot cars where crews are working. Drivers should expect delays. In order to see where crews are working, travelers should sign up for updates on the project website.
Rainbow Bridge (Design: 2024-2026)
ITD is currently conducting soil and rock sampling in the area of the Rainbow Bridge for a project to build a new bridge over the North Fork of the Payette River in Valley County. Drivers can expect 15-minute delays on weekdays in June. To learn more about the project visit https://itdprojects.idaho.gov/pages/rainbowbridge.
SH-55 DMS Sign (Construction: fall 2024)
ITD will install a dynamic message sign on SH-55 between Round Valley and Cascade. The new message board will notify motorists of detours or incidents along SH-55. Minimal delays expected. Any traffic impacts during the installation will be posted at 511.idaho.gov.
Flaggers will direct traffic at the Banks-Lowman intersection on all Sundays in July. The project team is planning to install an interim traffic signal at the busy intersection later this year.
SH-55 Fleming Creek Bridge Replacement (Construction: fall 2024 – late 2025)
This fall ITD will begin replacing the Fleming Creek Bridge on SH-55 approximately four miles south of Banks. SH-55 will be reduced to one lane in the work zone with speed limit reductions during the week. Details will be posted to itdprojects.idaho.gov later this summer.
SH-55 State Street to Horseshoe Bend Rehabilitation (Construction: fall 2023 – fall 2024)
ITD is milling and resurfacing SH-55 between State Street in Eagle and Horseshoe Bend. Work is expected to be complete this fall. Details are available on the project website. Drivers are encouraged to slow down in the work zone as there have been too many close calls with flaggers.
It’s important for motorists to plan ahead this summer by checking traffic impacts on their route at 511.idaho.gov.
The Idaho Transportation Department is advancing several projects this summer along State Highway 55 north of Boise.
The Idaho Transportation Department (ITD) is applying a hot chip seal to more than 100-lane-miles in the heart of Boise with minimal impact to drivers, as the work will all be done at night. This new innovative approach to chip sealing highlights ITD’s dedication to embracing new technologies that lessen impacts to users.
Unlike a regular chip seal, the hot chip seal on this project allows all work to be conducted at night. Traditional chip seal uses oil heated to around 150 degrees that can be applied during daytime high temperatures. Hot chip seal requires oil to be heated to 300 degrees so it can be applied during nighttime lows. Another key advantage is that drivers can use the roadway within 30 minutes of chip sealing, compared to the 24-hour wait required by regular chip seals. This high-temperature process not only extends the pavement’s service life but also minimizes disruptions to businesses and motorists.
Crews are beginning work on Broadway Avenue tomorrow, followed by State Street between State Highway 16 and Linder Road, and Chinden Boulevard. Work is weather dependent and can change. The project is expected to finish late summer of this year.
During construction motorists can expect:
Work on one section of road at a time
Nighttime work from 9 p.m. to 6 a.m.
Access to residences and businesses will be maintained at all times
Lane closures, with at least one lane open in each direction
Shifting traffic patterns
Flaggers in the roadway
Speed limits reduced
In anticipation of this project, last summer ITD applied the first ever hot chip seal on two miles of State Highway 21 to ensure results could be replicated in a busier environment. These projects are the first in the state to use this process.
The Idaho Transportation Department (ITD) is asking drivers to slow down and watch for construction crews on State Highway 55 south of Horseshoe Bend due to recent dangerous driver behavior in the area.
“There have been a couple of close calls in the work zone with drivers ignoring the flagging crews and the posted speed limit. Safety is our highest priority, so we really need people driving in the area to pay attention,” Project Manager JD Lewelling said.
Ongoing work includes milling and resurfacing the roadway for a smoother driving experience. Safety improvements include replacing guardrail, as needed, throughout the project area.
Construction activity is currently focused on the highway approximately four miles north of Avimor to just south of the Payette River Bridge in Horseshoe Bend. The project also includes constructing a bridge to convey both vehicle and pedestrian traffic under SH-55 at the north end of Avimor. This work is being funded by Avimor.
ADA improvements at SH-55 intersections with Hill Road, Floating Feather Road, and Beacon Light Road will be completed later this summer.
Construction is expected to be complete by this fall.
A major traffic shift will begin Saturday as the Idaho Transportation Department (ITD) prepares to widen westbound Interstate 84 between the Centennial Way and Franklin Road interchanges.
All traffic will shift to the eastbound lanes between the Centennial Way and Franklin Road interchanges. The traffic shift will be completed over two weekends in June. Motorists should anticipate I-84 ramp closures, detours and lane restrictions. These new traffic patterns will remain in place until summer 2025.
Once the traffic shift is complete motorists can expect:
All lanes of I-84 will be on the eastbound side. Two lanes will be open in each direction, but lanes will be narrower.
Traffic will use temporary off-ramps at Centennial Way and 10th Avenue (Exits 27 and 28). Temporary ramps will be shorter and may have fewer lanes than current ramps.
Frontage Road and Hannibal Street will be reduced to one-way traffic with flaggers.
Intermittent closures on 10th Avenue will begin in July.
The pedestrian overpass over I-84 will be closed and detoured to 10th Avenue in late summer.
This project will increase capacity and improve traffic flow for years to come.

The Idaho Transportation Department (ITD) will begin soil and rock sampling this June for a project to build a new bridge over the North Fork of the Payette River in Valley County. The project will address plans for the nearby Rainbow Bridge that has served Idaho travelers for nearly 100 years.
The sampling will require test drilling in 18 locations around the existing bridge. Preparations are expected to begin next week. Drivers can expect up to 15-minute delays on weekdays in June for the drilling and associated preparations. Work will stop for the weekend each Friday at noon.
Prior to the drilling, ITD will remove trees and vegetation near each drilling location to allow a helicopter to safely lower equipment. The ground will be re-seeded after drilling. Results will be used for designing the bridge foundation, supports and retaining walls along State Highway 55.
The current Rainbow Bridge was constructed in 1933 and no longer meets standards for state highway bridges. ITD began environmental and design work this spring for a new bridge adjacent to the current bridge. The project will include a decision about the future of the existing bridge.
“We intend to approach this project with a high level of transparency, sensitivity and community involvement,” ITD Resident Engineer Dan Gorley said. “Public input will be a key consideration in the final recommendation for the new bridge and the existing bridge.”
ITD will host community open houses and a stakeholder working group this July. Additional community involvement opportunities will be scheduled later this year. To request an invitation to future meetings, please email info@sh55rainbowbridge.com or visit https://itdprojects.idaho.gov/pages/rainbowbridge.
The project is planned for construction in 2027 or 2028.
