POCATELLO – Drivers on I-15 northbound heading west on I-86 toward Chubbuck will be detoured several days in the next week as crews install girders at the System Interchange. Ongoing construction at the System Interchange will improve safety and mobility while replacing bridges built in the 1960s.
Girders are horizontal steel beams designed to support the bridge deck. As the beams will be placed over the northbound to westbound ramp it is necessary to close the roadway beneath for the safety of the travelling public.
Traffic will be directed to the Northgate Interchange, adding approximately five minutes to travel times. Detours are expected to be in place from 5 a.m. to 8 p.m. the following days:
- Thursday, Aug. 17
- Monday, Aug. 21
- Tuesday, Aug. 22
Motorists should exercise additional caution while travelling through the construction zone. Those wishing to receive email updates about the System Interchange project can sign-up at this link – https://lp.constantcontactpages.com/su/g9MMkN9. Drivers can also check or download the 511 app for the last traffic conditions on all state highways and freeways.
The detour through the Northgate Interchange will exit at Northgate, cross over I-15, and then proceed south on I-15.
JEROME – The Idaho Transportation Department (ITD) has installed variable speed limit signs to improve safety as crews widen I-84 between the South Jerome and Twin Falls Interchanges. The new signs are controlled remotely, allowing ITD to lower speeds when crews are working near traffic.
The current posted speed limit in the work zone is 70 mph. When crews are working near traffic, ITD will lower the speed limit, and a flashing beacon will notify drivers that speed limits have been lowered. When crews are not as close to traffic, ITD will raise the speed limits to 70 mph.
Variable speeds have been successfully implemented in other work zones, including the one on I-84 between Caldwell and Nampa. Research shows that variable speed limits reduce crashes, reduce travel times, and improve safety.
The signs will be removed when construction is complete in late fall of 2025.
Details about the I-84 South Jerome to Twin Falls project are available at ITDProjects.org/84jerometotwin or by texting 84JTF to 1-866-483-8422.
POCATELLO – Beginning Monday August 7, the Idaho Transportation Department will be resurfacing Interstate 15 from the Rose Interchange 7 miles north to North Lava Rocks. Crossovers will be used to move traffic to the other side of the interstate while work is being done. Motorists should expect reduced speeds during construction. Construction will pause each Friday morning to accommodate weekend traffic.
Work will continue until September 1 when it will be paused for a week to accommodate increased traffic during the Eastern Idaho State Fair. Afterward the project will resume for four additional weeks.
Motorists should check https://511.idaho.gov or download the 511 app for the latest information on road construction.
KASOTA – The I-84 Kasota interchange westbound ramp will be closed starting July 23 at 9 p.m. to July 28 at 6 p.m. for construction. Motorists can expect reduced speeds and are encouraged to find alternate routes.
Due to the proximity of construction equipment to the westbound off-ramp, crews will need to temporarily close the ramp while performing concrete paving operations for safety reasons.
Travelers are reminded to check 511.idaho.gov for impacts to traffic from construction.
HAILEY – The Idaho Transportation Department (ITD) will begin chip sealing Main St. in Hailey starting July 25 and expect to complete work in four weeks. Construction will start at milepost 115.6 Fox Acres Rd and end at milepost 117.3 McKercher Blvd. Chips placed during sealcoats have the potential to cause windshield damage, so drivers are cautioned to drive slow on loose chips and pay attention to flaggers and no-passing zones throughout the work area.
Chip sealing involves applying a thin film of heated asphalt liquid that is sprayed on a road surface, followed by placing small aggregate chips on top, and then compacted to adhere to the asphalt. The cost benefits of chip sealing help to extend the life of the pavement for many years.

Drivers should check 511.idaho.gov before traveling to plan for impacts from this project and other work zones.
The Idaho Transportation Department is continuing work on I-84 between the South Jerome (Exit 168) and Twin Falls (Exit 173) Interchanges. Crews are blasting rock in the median of I-84 on weekday afternoons through mid-July.
What you need to know:
- Rolling closures will occur on I-84 through mid-July.
- Delays will range from 20-30 minutes.
A pilot car will slow motorists down several miles before the blast area to allow crews to blast rock and clean up debris.

SHOSHONE — The Idaho Transportation Department (ITD) is seeking feedback on the just-released draft Idaho Transportation Investment Program (ITIP). The 2024-2030 ITIP outlines the state’s transportation priorities and guides investment decisions for the next seven years. ITD encourages everyone to review the draft and provide comments from July 1-31.
Transportation projects included in the draft ITIP range from large-scale interstate improvements to smaller projects like the installation of a new guardrail. Projects are located throughout Idaho’s 44 counties and involve all modes of transportation. Project selection is determined through technical data, as well as input from local officials and residents.
To review the complete draft plan visit itd.idaho.gov/funding to view an interactive map that allows users to learn about projects in their local area as well as submit a comment through the portal.
Local projects in the program include:
- A project to reconstruct the roadway on SH-75 from Saddle Road in Ketchum north to North Fork Campground Road.
- Bridge replacements on US-30, Bickell Railroad Overpass at milepost 231.9 near Murtaugh, and SH-75, Yankee Fork of Salmon Road at milepost 202.48 downriver from Stanley.
- A reconstruction and realignment safety project on SH-75 at Torrey’s Hole RV access to Slate Creek that includes new pavement surface, riverbank stabilization, culvert installation, and installing guardrail.
- A safety and restoration project along US-93 from Hot Springs Road to Fish Creek Road north of Carey to restore deficient pavement, repair frost damage and apply a seal coat to provide a new roadway surface.
- Road widening with four lanes on US-93 from Jerome Butte, SH-25, north to R Canal.
Comments will be taken from July 1-31 and can be emailed to itipcomments@itd.idaho.gov or mailed to:
ITIP – Comments
Attn: Office of Communication
P.O. Box 7129
Boise, ID 83707
Paper copies of the ITIP will be provided upon request by contacting the Idaho Transportation Department (208) 334-8119.
All comments will be reviewed and incorporated into the ITIP where appropriate. Responses will be sent in September once the comment period has ended.
After approval by the Idaho Transportation Board in September, the ITIP will then be submitted to the Federal Highway Administration, the Federal Transit Administration, and the Environmental Protection Agency in October. Once finalized, ITD staff across the state will begin scoping new projects.
Public input is crucial in ensuring that the ITIP reflects the needs and desires of Idaho’s communities.
