Construction is underway to widen I-84 between South Jerome and Twin Falls interchanges

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.

Idahoans value work zone safety

The Idaho Transportation Department is joining states across the country for National Work Zone Awareness Week. The national and state campaigns this week are designed to raise awareness and educate the public about the safety measures we can all take in work zones, and how we are all responsible for work zone safety.

From 2017 to 2021, Idaho saw 3,119 crashes in work zones resulting in 36 deaths, stressing the need for this year’s theme: “You play a role in work zone safety. Work with us.”

This special week includes a schedule of activities; everyone is encouraged to go orange for safety on Wednesday and observe a moment of silence on Friday for those who have died in work zones.

“Work zone safety is drivers and highway workers cooperating together to slow down and improve safety,” said Dan McElhinney, Chief Deputy and Chief Operations Officer for ITD. “ITD employees and contractors design traffic control with signs, cones, beacons or reduced speed limits to help guide vehicles through these hazard zones, knowing we really appreciate drivers being engaged without distractions for success. Let’s all get home safely every day.”

Work zone crashes are preventable. The top three causes of crashes from 2017 to 2021 were following too closely, distracted or inattentive driving and failing to yield.

Drivers should:

Plan ahead – Check 511.idaho.gov before you go to plan your route. Expect delays, leave early or take an alternate route if possible.
Slow down– drive the posted speed limits.
Pay attention– both to workers directing you and surrounding traffic.

Other safety tips and videos are available at itd.idaho.gov/travel.

Overnight lane reductions next week on the Perrine Bridge

On Tuesday (Jan. 17) crews will close lanes on the Perrine Bridge to replace luminaire wiring. To help lessen impacts to commuters, work will take place after 9:00 p.m.

“This work is dependent on the weather and may need to be rescheduled if inclement conditions occur,” ITD Project Manager John Keifer stated. “Crews should be able to move quickly, and we anticipate all work being completed in one night.”

While workers are on the bridge, traffic will be reduced to a single lane in each direction.

Motorists are advised to drive engaged and watch for crews and equipment in the area.
