Starting tonight the contractor will return to Chinden Boulevard to address the limited sections from last year’s chipseal project that did not meet ITD standards. Repairs will protect the driving surface and extend the life of the roadway.
Between Glenwood Street and Eagle Road, the highway will receive a thin asphalt overlay resurfacing. From Eagle Road to Linder Road, pavement sealer will be sprayed on to the road to protect it, and lines will be freshly painted.
Work will be done at night from 7:30 p.m. to 5 a.m. to minimize impacts to travelers. One lane will be closed in each direction at night for up to six weeks. All lanes will be open during the day when crews are not on site.
Travelers should check 511.idaho.gov to know before they go.
The Idaho Transportation Department will close I-84 under the Karcher Interchange Tuesday and Wednesday nights to place girders on the overpass bridge. Detours will be in place.
Closures will run from 10 p.m. to 5 a.m. each night. On Tuesday night, westbound traffic will be affected, and on Wednesday night, eastbound traffic will be affected.
Motorists traveling westbound on I-84 Tuesday night will:
- Exit I-84 at the Northside Interchange (Exit 35).
- Travel north on Northside Blvd.
- Turn left on to Karcher Road.
- Travel west until you reaching the Karcher Interchange westbound on-ramp.
- Use the Karcher Interchange westbound on-ramp to merge back on to westbound I-84.
Motorists traveling eastbound on I-84 Wednesday night will:
- Exit I-84 using the Karcher Interchange eastbound off-ramp (Exit 33).
- Cross Karcher Road.
- Use the eastbound on-ramp to merge back onto I-84.

The girders were fabricated locally and will support the new westbound lane on Karcher Road over the interstate. ITD will host a Facebook live event during the girder placement on Tuesday, June 10. To tune in visit the ITD Facebook page.
Improvements on this project include:
- Adding a free running right hand turn at the westbound off-ramp
- Paving a third westbound lane on Karcher Road from the westbound off-ramp to Sundance Road
- Reinforcing the Karcher Interchange and Indian Creek bridges to support the new lane
- Updating signal equipment and adding a pedestrian flashing beacon at the eastbound on-ramp
- Building a separated mixed-use path on the north side of Karcher Road
These improvements will increase safety and traffic flow at the interchange. Construction is expected to finish in fall 2025.

Traffic leaving U.S. Highway 20 to access South Rigby will be detoured on Monday through Wednesday, June 11, while the exit is closed for bridge repairs. The closure will be in effect from 8 a.m. to 5 p.m. and last until complete on Wednesday.
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.
Beginning Monday the Idaho Transportation Department will close Chubbuck Road underneath Interstate 15 to add facilities for bicyclists and pedestrians. The underpass was partially completed and opened for the school year, but with schools out for the summer the contractor will be returning to complete work.
Construction is scheduled to be completed by the end of the month. Traffic will be detoured through the Northgate Interchange while work continues.
The old Chubbuck Road Overpass, built in 1962, made it difficult for large loads travelling north and south on I-15 due to its limited height. As part of the System Interchange project, the department decided to transform Chubbuck Road into an underpass to eliminate height restrictions. The new design includes additional facilities for pedestrians and cyclists. Those changes necessitated a closure for demolition in 2022 and the construction of the two newly completed bridges to carry I-15 over Chubbuck Road.
Originally built in the 1960s, the Interstate 86 and I-15 System Interchange is undergoing a rebuild to improve safety and replace aging infrastructure. Work began in 2022 and is scheduled to be completed this year.
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 travel safely.
Motorists are encouraged to use 511.idaho.gov or the 511 app to keep track of project detours. Project details are available on ITD’s projects website at itdprojects.idaho.gov/i-86i-15-system-interchange.
Daytime intermittent closures on U.S. Highway 95 between Moscow and Lewiston near Thorn Creek/ Uniontown Cutoff will be in effect next Wednesday and Thursday, May 28 and 29, from 6 a.m. to 6 p.m. while the Idaho Transportation Department is installing new bridge girders at the Thorn Creek Bridge.
The bridge will fully close to both north and southbound traffic while each girder is installed. Girders are the large horizontal beams that will support the new bridge deck being constructed this summer.
Flaggers will be present to allow traffic to pass one direction at a time between each girder installation. Motorists are encouraged to seek an alternative route to avoid delays.
This work at Thorn Creek Bridge is part of a large-scale project improving safety along US-95 from Lewiston to Moscow. Portions of this project are funded as part of Idaho Governor Brad Little’s Leading Idaho transportation funding initiative. These funds are used to make investments in critical state infrastructure to enhance safety, mobility and to sustain Idaho’s strong economy into the future.
Digital message boards are currently in place to alert drivers of these closures next week. Updates can also be found on the Idaho 511 app and at https://511.idaho.gov/.
Southbound traffic is now able to travel over the Stoddard Creek Bridge at Interstate 15 Exit 184 just in time for the Memorial Day weekend. Travelers can now turn both right and left onto Stoddard Creek Road underneath the bridge. This road provides access to multiple camping and recreational opportunities in the area.
Southbound 1-15 traffic is no longer diverted onto the Exit 184 ramps, but back onto one lane over the Stoddard Creek Bridge along the main roadway. This one lane closure allows the Idaho Transportation Department and contractor partners to accomplish finishing work, like replacing guardrails, on the passing lane of I-15. Work is expected to be complete and all traffic restrictions removed within the next month.
This update can be seen on the Idaho 511 app and at https://511.idaho.gov/.
REXBURG—The Idaho Transportation Department, in partnership with Union Pacific Railroad, will close highways near several railroad crossings in May.
State Highway 33 from Rexburg to Sage Junction will close Monday through part of Tuesday as needed (May 19-May 20) as Union Pacific Railroad replaces crossings along this route. Motorists can take State Highway 48 to Roberts and Interstate 15 to Sage Junction as an alternative.
SH-48 through the town of Roberts will close through the weekend of May 31-June 3 as three parallel railroad crossings and paving are conducted there as well. I-15 can be accessed at the Osgood Interchange south of Roberts as an alternative.
Digital message boards will be in place along both routes prior to these closures to give motorists advance warning time for making alternative travel plans. Updates regarding these closures will be posted on the Idaho 511 app and at 511.idaho.gov.
REXBURG— One lane and full closures at Exits 332 and 333 off U.S. Highway 20 in Rexburg are ongoing today and into next week. These restrictions are required so contractors can drill deep foundations for the large overhead signs that will soon be the finishing touch on the Diverging Diamond Interchanges completed last fall.
Both of these Rexburg exits will see one lane closures in the areas where drilling work is occurring. Traffic control will move with equipment and the road fully open wherever possible.
Next Monday, May 19 and Tuesday, May 20 Exit 333 will be fully closed overnight from 7 p.m. to 7 a.m. ITD and contractor partners are working through the night so traffic can flow as usual through the daytime hours.
Large equipment, including a drill rig to reach the required 18-foot foundation depth, will need to be in the roadway underneath US-20 for work at both locations, reaching across and over the median concrete barriers. To keep everyone safe and be able to swiftly clean up any water or debris that the drilling creates, lane restrictions and closures have been deemed essential. ITD and contractor partners are committed to completing the work as quickly as possible to cause the least amount of traffic disruption.
“The foundation for the bridge and cantilever posts that will hold the large overhead signs has to be particularly deep,” Resident Engineer Curtis Calderwood stated. “We want them to be secure and have integrity in the wind. This is pretty well the last holdout for getting the exits truly finished.”
These restrictions and closures will be noted on the Idaho 511 app and at 511.idaho.gov.
The Idaho Transportation Department is continuing repairs to the Stoddard Creek Bridge at Exit 184 on Interstate 15. Stoddard Creek Road underneath the I-15 bridge is closed for safety, as crews work to demolish the current bridge deck above.
Both northbound and southbound travelers exiting the freeway will only be able to make right turns from the ramps on to Stoddard Creek Road. Drivers cannot turn left and travel underneath the closed bridge. This restriction will remain in effect until work is completed, which is estimated to be late spring.
The recreational parking area west of the Stoddard Creek Exit is only directly available for southbound I-15 drivers. Northbound traffic needing to access the recreational parking area should proceed six miles to Humprey Exit 190, then head back southbound to exit at Stoddard Creek. From this direction, a right turn to the parking area can be safely completed.
Updates on this closure and construction can be found on the Idaho 511 app and at 511.idaho.gov.
Bathroom facilities at the Clark Hill Rest Area along U.S. Highway 26 between Ririe and Swan Valley will close beginning Monday through February 28 for the Idaho Transportation Department to make repairs and upgrades to the facility.
This popular rest area at milepost 357 features a view of the South Fork of the Snake River. The parking lot and scenic overlook will remain open, with the buildings themselves out of service as repairs, deep cleaning and painting are completed in preparation for the busy summer months.
The closure will be noted and updates can be found on the Idaho 511 app and at 511.idaho.gov. The nearest rest area/public bathrooms can be found at Hilltop gas station in Ririe.
