UPDATE: E 400 South Road in Jerome will continue to be closed until late August.
JEROME – The Idaho Transportation Department (ITD) will close E 400 South Road under I-84. Closures will allow crews to begin work on the E 400 South Road bridges as they widen I-84 between the South Jerome (Exit 168) and Twin Falls (Exit 173) Interchanges.
Traffic will be detoured to Golf Course Road, E Frontage Road, E 300 S and S 200 E.
Intermittent closures of E 400 South Road will continue throughout the duration of the I-84 South Jerome to Twin Falls project. Construction is anticipated to be completed 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.
Drivers should check 511.idaho.gov before traveling to plan for impacts from this project and other work zones.
UPDATE: Daytime and nighttime ramp closure on the I-84 Westbound ramp Aug. 29 – Sept. 11. Daytime ramp closure affords construction crews the ability to expedite ramp paving. Project remains on schedule to be completed mid-October.
TWIN FALLS – The Idaho Transportation Department (ITD) begins construction on the I-84 and US-93 interchange on and off-ramps at Exit 173 in August 2023 which is expected to last approximately two months. Located just north of Twin Falls, the project will resurface the ramps, upgrade signals, and construct a right turn lane for the westbound I-84 off-ramp.
The public can expect the following traffic impacts:
- Lane reductions in place at the on and off-ramps south of I-84.
- Temporary closures will occur at the on and off-ramps 8 p.m. – 5 a.m.
- Motorists will drive on a gravel surface during the day on the westbound on and off-ramps.
- Construction will be staggered and no more than one ramp will be closed at a time.
- Each ramp closure is expected to last for approximately eight nights.
- Motorists will need to use alternate routes when closures are in place.
- Signs and possibly flaggers or a temporary signal will be in place to direct traffic.

Travelers are reminded to check 511.idaho.gov for impacts to traffic from construction.
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.
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.
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.

JEROME – As part of Governor Brad Little’s Leading Idaho Transportation initiative, the Idaho Transportation Department (ITD) has begun a project to widen I-84 between the South Jerome Interchange (Exit 168) and the Twin Falls Interchange (Exit 173). Construction begins this week on this 2.5-year project.
I-84 serves as a primary interstate route, and traffic counts are expected to increase substantially over the next 20 years. The existing interstate will not be able to accommodate anticipated future traffic volumes. These improvements will increase capacity and improve safety on I-84 to serve South-central Idaho for years to come.
In 2023, motorists should expect:
- I-84 will be restricted to one lane in each direction at night. Occasional daytime lane restrictions may be necessary.
- Rolling closures on I-84 will occur this spring/summer for blasting rock in the median.
- Traffic shifts will be used throughout construction.
- The speed limit on I-84 will be reduced.
- 400 South Road will be closed intermittently.
Funding for this project comes from the Leading Idaho TECM Program. The program allows ITD to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build. Concrete Placing Company is the contractor for this $92.9 million project.
Construction is anticipated to be completed in late fall of 2025. Those who are interested in learning more about the project are invited to visit the project website at itdprojects.org/84jerometotwin or call (208) 391-3735.
Information in Spanish can be found on the project website or by calling (208) 398-3696.

The Leading Idaho initiative allows ITD to take a deliberate approach to advance large projects that will enhance safety, improve mobility, further strengthen Idaho’s economy, and positively impact the Mini-Cassia region and communities across the state for years to come.
The Idaho Transportation Department (ITD) is holding an in-person meeting tomorrow (June 14) to share plans for widening Interstate 84 from the South Jerome Interchange to the Twin Falls Interchange. The meeting will be held at Con Paulos Chevrolet in Jerome from 4:30 p.m. to 6:30 p.m.
The meeting will be held in open-house format and provide members of the public an opportunity to review design plans and provide input. If individuals are unable to participate at the in-person meeting, a self-guided online meeting option will be available from June 14 until June 28 at itdprojects.org/84jerometotwin.
The interstate serves as a major corridor through South-central Idaho and beyond, with traffic counts expected to double over the next 20 years. The purpose of this project is to increase capacity and improve safety. Once funding has been confirmed, construction may start as early as 2023.
“Widening this section of I-84 will allow us to proactively address capacity and safety needs between Jerome and Twin Falls,” said ITD Engineering Manager Crystal Craig. “We are advancing this project to construction as soon as possible and plan to keep the public involved through each phase.”
This design project is funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of Governor Little’s “Leading Idaho” initiative. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build. Construction funding will be identified at the time that the project is ready to advertise for construction bids.
