Beginning tomorrow evening the north-to-west ramp of the System Interchange at Pocatello will be periodically closed to allow for girder placement for a new bridge.
Girders are horizontal steel beams designed to support the bridge deck. As the beams are placed over the northbound to westbound ramp it is necessary to close the roadway beneath for the safety of the travelling public.
Closures are scheduled for:
Wednesday from 9:00 p.m. until 1:00 a.m.
Friday from 8:00 p.m. until 6:00 a.m.
Monday July 22 from 8:00 p.m. until 6:00 a.m.
Wednesday July 24 from 8:00 p.m. until 6:00 a.m.
Thursday July 25 from 8:00 p.m. until 6:00 a.m.
Traffic traveling north on I-15 wishing to proceed west on I-86 toward Chubbuck will be detoured through the Northgate Interchange.
Motorists should carefully follow signs and posted speed limits while traveling through the construction area. With crews working day and night at the System Interchange it is especially important that drivers be alert and proceed safely through the work area.
The Idaho Transportation Department will begin the first of two ramp closures on Monday along Interstate 84. These closures are necessary in order to safely pave the ramps.
To minimize traffic impacts, ITD will conduct nighttime paving on both ramps. Each closure will begin at 8 p.m. and will reopen to traffic the following day by 5:30 a.m. Traffic control will be in place prior to any closures. The scheduled ramp closures, which are weather dependent, are as follows:
July 15: I-84 Eagle Road eastbound off-ramp
July 16: I-84 Eagle Road westbound off-ramp
July 17: I-84 Eagle Road westbound off-ramp
“While a standard pothole patch might last a few months to a year, the repairs we achieve with these overnight closures will last multiple years. This not only minimizes the need for constant maintenance but also significantly reduces the disruption for drivers,” Field Operations Manager Eric Copeland said.
Drivers are encouraged to use the Idaho 511 system by phone, online, or through the app for updated closure information.
Construction by the Union Pacific Railroad is underway to extend a siding track line near Parma that will result in the closure of the railroad crossing on Deb Lane and loss of direct access to U.S. Highway 20/26. Work began on Tuesday, and the permanent closure of the railroad crossing will occur on July 26.
To access US-20/26 after the crossing is removed, drivers should instead cross the railroad line and access the highway via the U.S. Highway 95 Interchange to the west. Crews will build a cul-de-sac at the end of Deb Lane so vehicles can turn around.
Changes were collectively agreed upon between the Union Pacific Railroad, the Idaho Transportation Department and the Notus-Parma Highway District #2. Increased rail activity is expected with the extension of the track line. Given increased train activity and the proximity of other crossings, stakeholders agreed it was appropriate to permanently close the Deb Lane crossing.
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.
RIGBY— 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.
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.
Stay up to date on further status of this project and others by visiting 511.idaho.gov, calling 5-1-1 or downloading the app.
The Idaho Transportation Department (ITD) is performing maintenance work this summer on five Boise bridges along the Connector (Interstate 184). Crews will start work on the I-184 bridge over Chinden Boulevard on Monday.
The bridges included in this project are:
Curtis Road Interchange
Fairview Avenue eastbound on-ramp over I-184
Orchard Street Bridge
I-184 over Chinden Boulevard
Boise River Bridge
Crews will apply epoxy overlays to seal the driving surface, patch and repair bridge decks, and perform joint work to enhance safety and extend the service life of each bridge. The specific work will vary depending on the bridge. The project is expected to be complete this fall.
Motorists should expect lanes and ramps along I-184 to be restricted or closed overnight and speed limits to be reduced. Check 511.idaho.gov to plan your route in advance.
