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.

The interchange redesign project is being funded as part of Idaho Governor Brad Little’s “Leading Idaho” transportation funding initiative. 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.

The Idaho Transportation Department (ITD) is hosting a public meeting to present final design plans for the reconstruction of the Interstate 84 South Jerome Interchange (Exit 168). The meeting will be held in open house format on December 9 and will feature displays illustrating the new design.
The public is invited to attend anytime between 4 p.m. and 7 p.m. at the Jerome City Council Chambers located at 100 East Avenue A in Jerome. Members of the project team will be on-hand to answer questions and accept comments during this time.
For individuals who are not able to attend the open house in person, a self-guided online meeting option will be available between December 9 and December 30 at itdprojects.org/projects/i-84-south-jerome-interchange.
Originally built in 1966, the current interchange has reached its life expectancy and is in need of replacement. ITD has been working with stakeholders and engaging the public since 2017 to develop a design that will meet the needs of the community and accommodate future growth in the area.
Construction on the interchange is scheduled to begin in Fall 2023.
If individuals have questions or comments about the project and are unable to attend the in-person or self-guided online meetings, contact ITD Project Manager Nathan Jerke at (208) 886-7809 or nathan.jerke@itd.idaho.gov.
Drivers can expect additional lane restrictions near Jerome next week as crews from the Idaho Transportation Department (ITD) perform a routine bridge inspection on Interstate 84.
On April 15 crews will inspect the bridge located near milepost 163. They will examine the bridge deck and deploy ITD’s under-bridge inspection truck from the eastbound lanes of I-84 and from the county road on the north side of the interstate.
Traffic will be reduced to one lane while inspections are underway. Work is expected to take place from 8 a.m. to 12 p.m.
“We will begin with a left-lane closure in the I-84 eastbound lanes and then alternate to a right-lane closure as our inspection progresses,” said ITD Bridge Inspector Amy Bower. “These lane restrictions are separate from the nearby work zone between Jerome and Twin Falls, so it’s important that drivers are attentive when traveling on this section of I-84.”
Drivers are urged to exercise caution near the work zones and watch for crew members and equipment. ITD appreciates the patience and cooperation of those driving through the area.
Work is expected to resume next month (March 8) on Interstate 84 between Jerome and Twin Falls (milepost 166 to 173). This is part of a larger construction project that began last year to provide a safer and smoother roadway.
“In 2020 we completed the westbound lanes,” ITD Project Manager Brock Dillé said. “In addition to rehabilitating seven miles, we also increased the length of ramps at interchanges, improved lighting and upgraded stormwater drainage. This year, we will complete work on the eastbound lanes of the highway.”
While construction is underway, traffic will be reduced to a single lane in each direction.
“Drivers will utilize the same crossovers and temporary ramps we constructed last year to keep traffic moving during construction,” Dillé said. “Various activities may require changes in traffic patterns so it’s important that motorists pay attention to signs and not follow GPS while traveling through the work zone.”
Motorists should anticipate reduced speeds and watch for workers and heavy equipment. Electronic message boards and signage will be in place to direct drivers through the area.
Western Construction of Boise is the general contractor for this $15 million project that is expected to be complete midsummer.
The westbound off-ramp at Exit 1 on Interstate 86 at the Salt Lake Interchange is expected to be closed tomorrow (Dec. 3) from 8 a.m. to 5:30 p.m.
Motorists heading west from Pocatello to Salt Lake will need to take Exit 216 at the Declo Interchange and re-enter I-84 toward Salt Lake. Eastbound traffic will not be affected by this closure.

“This is follow-up work in connection to the closure that occurred late last month. It will be a short duration closure that will allow us to smooth the asphalt on the off-ramp,” Project Manager Travis Hitchcock said. “The asphalt work and additional signage installation are the remaining items left for this project.”
Drivers are urged to pay close attention to signage and message boards that will direct them through the area.
Wadsworth Brothers Construction of Draper, Utah, is the primary contractor on this project that involves replacement of an aging interchange with a new structure that will better serve motorists in the region.
The westbound off-ramp at Exit 1 on Interstate 86 at the Salt Lake Interchange is expected to be closed from 8 a.m. to 5:30 p.m. tomorrow and Friday (Nov. 19-20).

“Work on the off-ramp must be done during the day when temperatures are high enough to properly seal the asphalt,” Project Manager Kenny Lively said. “This is one of the final steps needed for us to complete the project this winter.”
Drivers are urged to pay close attention to signage and message boards that will direct them through the area.
Wadsworth Brothers Construction of Draper, Utah, is the primary contractor on this project that involves replacement of an aging interchange with a new structure that will better serve motorists in the region.
As early as Thursday (Oct. 15), traffic will shift on Interstate 84/86 at the Salt Lake Interchange project. Motorists traveling toward Pocatello from Burley on I-84 will be detoured toward Salt Lake. They will take Exit 228 at Yale Road and then enter I-84 westbound and continue on to I-86 toward Pocatello.
“This detour will allow us to complete demolition of the aged eastbound bridge structure.” ITD Project Manager Travis Hitchcock said. “This will be the final demolition phase for this project.”
In addition to the Yale Road detour, westbound traffic progressing from I-86 to I-84 will now continue through the work zone in their designated lane of travel.
“These are new traffic patterns which replace others previously in place throughout this project,” stated Hitchcock. “It’s important that drivers pay close attention to signage and message boards that will be in place to safely direct them through the area.”
Traffic will remain reduced to a single lane in each direction. Drivers should continue to anticipate reduced speeds through the work zone and watch for crews and heavy equipment.
Wadsworth Brothers Construction, of Draper, Utah is the prime contractor on this project.
