On Monday the Idaho Transportation Department will begin work to repave the northbound lanes of Interstate 15 from the West Blackfoot Interchange Exit 93 to Riverside Canal near the Rose Road Interchange Exit 98. This project will improve safety and the drivers’ experience with a smooth new surface.

During construction traffic will be shifted to the southbound lanes through a crossover. Drivers should expect reduced speeds through the construction zone. The project is expected to take 50 days to complete.

Throughout the course of the project, crews will be milling down the base layer of the highway to fully reconstruct the road base and driving surface. Work includes pulverizing the existing asphalt, excavating and placing new material as a base, and then paving over the top of the new base.

Travelers are encouraged to use the Idaho 511 system for updated traffic impacts through the construction season.

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.

Sealcoat from Homedale to Oregon border set to begin Wednesday

SH-19 sealcoat will begin in July and be finished in August 2024.

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.

I-84 eastbound ramps at Simco Road set to close Monday for more than a month

The eastbound on-ramp and off-ramp on I-84 at the Simco Road Interchange (Exit 74) will be closed for construction starting Monday.

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.

US-20 Exit 332 to re-open in Rexburg, expect continued construction

Graphic of US-20 Exit 332 detailing how to drive through a diverging diamond interchange

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.

Thanks to new innovation, ITD will chip seal 100 lane miles in the heart of Treasure Valley with minimal impact to drivers

New innovation allows ITD to do 100-lane-miles of hot chip seal in heart of Boise area. 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.

The Idaho Transportation Department 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.

Drivers asked to slow down in work zone on SH-55 after too many “close calls”

ITD is asking drivers to slow down and watch for construction crews on State Highway 55 (SH-55) south of Horseshoe Bend due to recent dangerous driver behavior in the area.

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.
