POCATELLO – The Idaho Transportation Department will close the Rose Road Interchange (Exit 98) for paving on Tuesday, September 3 from 7 a.m. to Thursday, September 5 at 7 p.m. The north and southbound off-ramps will also be closed during this time.
Traffic will be detoured around the closure and will be notified with digital messaging boards prior to the closures. See detour map.
This work is a part of a year-long project to reconstruct the interchange at Rose Road (Exit 98) on Interstate 15 to maximize the safety and mobility for motorists using this interchange. Construction includes widening the Rose Road overpass and increasing its vertical clearance, reconfiguring and lengthening the interchange ramps, and replacing two canal structures to support current traffic loads.
The interchange is expected to open later this year with additional construction activities to be completed in Spring 2020.

There will be temporary closures on Idaho Highway 55 at the Snake River Bridge in Marsing while girders are placed for the new bridge.
Girders are large horizontal beams that support the surface of the bridge. Each girder weighs 141,000 pounds and is 148 feet long. Current plans call for girders to be placed overnight on Tuesday Sept. 3, Thursday Sept. 5, Friday Sept. 13, and Monday Sept. 16. This is subject to change.
Sunny Slope Rd. southbound will be reduced to one lane between Lowell and True road. The lanes will be restricted from noon to 2:00 am each night to stage the bridge girders. Placement of the girders will generally occur between the hours of 10:00 pm and 2:00 am. Traffic will be stopped for up to thirty minutes while each girder is placed. Each night up to three girders will be placed.
This work is part of a two year-long project to replace the Snake River Bridge in Marsing The project will improve safety and driving conditions on the bridge, which is the primary river crossing for the area. More information can be found at https://itdprojects.org/marsing55improvements/.
With shorter daylight hours, construction delays on US-95 in Culdesac Canyon near Winchester are shifting earlier and expected to affect evening commutes as fall conditions require a change in the contractor’s blasting schedule.
Since construction began in April to extend a passing lane through the rocky canyon, closures for blasting have typically been scheduled to start at 7 p.m., but dwindling daylight now requires blasting to occur before sunset.
Next week, rock excavation and cleanup activities will begin at 6:30 p.m., and the following week they will begin at 6 p.m.
Temporary closures are still expected to last up to 1.5 hours, with up to three closures possible each week. They are advertised on 511.idaho.gov and on message signs stationed near the project.
Work this season is expected to end by November, with the entire project scheduled for completion in fall 2020.
The signal at US-95 and ID-53 is planned for removal starting Monday, August 26 to allow construction of a new interchange at that location to improve traffic flow between Garwood and Sagle.
View a video of the design for the US-95, ID-53 interchange.
The removal process will take approximately three nights, during which US-95 will be reduced to one lane in each direction from 9 p.m. to 6 a.m. Idaho Highway 53 will also be closed to the west of the intersection as crews replace the bridge over the railroad and realign the highway to tie into the new interchange.
Starting Monday night, traffic will be detoured around the ID-53 closure via Old US-95 to Garwood Road to access US-95. This closure is expected to last until fall 2020 when the new railroad bridge and interchange open to traffic.
Government Way will continue to be closed at the US-95 intersection.
This project is part of a larger vision to maximize mobility on US-95 between Garwood Road and Sagle. Since construction began in July, a temporary signal has been installed at ID-53 and Ramsey Road to accommodate the change in traffic patterns, and ID-53 has been widened.
In 2020 and 2021, frontage roads and an overpass at Garwood Road will be constructed as part of this project. Total improvements, though not all awarded to contractors, are funded primarily with an estimated $41 million from the GARVEE program and another $13.9 million in federal aid.

ASHTON – Through Aug. 30, the Idaho Transportation Department (ITD) will be making safety improvements to the intersection of Idaho Highway 47 and US-20 through the city of Ashton.
Crews will install a flashing stoplight on ID-47 at the intersection, install rumble strips to alert drivers approaching the intersection, and the department will be reducing the speed limit on US-20 through Ashton from 45 mph to 35 mph. Future safety plans for the area include installing flashing school zone warning signs on US-20 through the city.
ITD first programmed a traffic signal at the intersection of US-20 and ID-47 at the request of the city. It was pushed back from 2020 to 2023, though, due to unforeseen issues during project design. Primary among those issues, the State Historical Preservation Office (SHPO) considers the Frostop Root Beer Sign(picture from East Idaho News) at that location to be historic, so ITD has been working directly with SHPO to ensure that impacts are mitigated as much as possible.
The eventual project is estimated to cost $1.5 million.
Drivers can expect lane restrictions and possible delays near Twin Falls next week as crews from the Idaho Transportation Department (ITD) place platforms underneath the Perrine Bridge for upcoming special inspections.
On Sunday, August 18 it’s anticipated that crews will utilize ITD’s under bridge inspection truck along the bridge deck. Southbound traffic will be reduced to one lane while the truck is in use.
Work is scheduled to occur on Sunday to help lessen traffic congestion through the area. Motorists may consider using an alternate route between the hours of 6:30 a.m. to 3 p.m.
Drivers are urged to exercise caution near the work zone and watch for crew members and equipment. ITD appreciates the patience and cooperation of those driving through the area.
The Idaho Transportation Department will begin repairs this week on Idaho Highway 75 in Blaine County. Work will occur on various stretches of roadway between milepost 118 and 132 on both north and southbound lanes.
Weather permitting, crews are anticipated to complete work by the end of August.
“We are working to fix areas of the highway which saw substantial damage over the lengthy winter months, including the corner of Elkhorn Road in Ketchum,” said ITD area foreman Brad Lynch. “This should improve the driving experience for motorists throughout the Wood River Valley.”
Some areas will require a detour while work is being performed. Motorists are advised to exercise caution and follow signs which will be in place to safely direct drivers through the area.
Repairs are expected to take place between 7 a.m. – 5 p.m. Work will not be performed over Labor Day weekend.
CHUBBUCK – The Idaho Transportation Department (ITD) will partner with the city of Chubbuck to replace a damaged signal cabinet at the intersection of Chubbuck Road and Yellowstone Avenue (US-91) on Sunday, August 11.
The signal cabinet to be replaced was heavily damaged last winter due a car accident. The cabinet was in working condition, though, and has been used until this replacement.
Work is expected to take just one day, beginning at 5 a.m.
The traffic signal at the intersection will be turned off until the replacement is complete. Appropriate traffic control will be set up and flaggers will be present to direct traffic.
ITD advises drivers to pay attention to the traffic control and please use an alternate route until the project is complete.
ASHTON – Starting Tuesday, August 6, Idaho Transportation Department (ITD) maintenance crews will lay intermittent asphalt overlays on Idaho Highway 47 between Marysville and Warm River to extend the life of the roadway. The project is expected to finish by Thursday, August 15.
Flaggers will be present and detour traffic as needed until construction is completed. Traffic delays could be up to an hour wait, so motorists are encouraged to consider taking an alternate route.
Travelers are advised to please watch for and follow traffic detour signs, drive safely and check 511.idaho.gov for current construction and traveler information.
POCATELLO – The Idaho Transportation Department (ITD) will divert Interstate 15 northbound traffic onto US-91 on Tuesday night, August 6, while girders are placed at the new Northgate Interchange from 10 p.m. to 5 a.m. Drivers will exit on Interstate 86 at Exit 61 (Chubbuck interchange) and re-enter I-15 at Exit 89 (South Blackfoot Interchange). Pictured are pillars used to hold the girders.
Traffic control will continue for those same hours Wednesday night, August 7, as ITD diverts southbound traffic on US-91. Drivers will exit I-15 at Exit 89 and re-enter at Exit 61 on I-86. ITD will also have traffic control set up at the Fort Hall Interchange to divert traffic as needed.
Girders are the massive concrete structures that will support the new bridge. The contractor will be placing 12 girders each night, 24 total, that are 85 ft. long and weight 120,000 lbs. each.
This work is part of a year-long project to construct the new Northgate interchange on I-15. The project is expected to be completed in late fall 2019.
