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.
Work continues on the Aht’Wy Interchange project on U.S. Highway 95 near the Clearwater River Casino & Lodge RV Park. As crews shift their work to other sections on the site, there will be a new change to traffic patterns starting this week.
Motorists are advised that access from SB US-95 to the plaza will only be allowed at the west entrance point. Access from NB US-95 to the plaza will be allowed at both west and east entrance points.
Access from the plaza to SB US-95 will be restricted at the east entrance and only allowed at the west entrance. Access from the plaza to NB US-95 will be allowed at both east and west entrance points.
To see a graphic for access to and from the plaza, please reference this handout
During these early stages, travelers can expect single lanes in each direction. The speed limit has been lowered for safety. ISP is heavily patrolling the area. Please be mindful of construction workers working near the roadway.

Underway since May 2018, substantial progress has been made on the Interstate 84/86 Salt Lake City Interchange in Cassia County. With this project, the Idaho Transportation Department is replacing the old interchange with a new structure that will meet current standards and provide a better driving experience for motorists.
“This is a vital travel and commerce corridor for not only this area, but for the entire state,” said ITD Project Manager Travis Hitchcock. “Our goal is to construct an interchange that will serve motorists for many years to come.”
As work proceeds, drivers should anticipate a continuation of reduced speeds and changing traffic patterns through the work zone.
“There will be varying detours over the next several months as work on specific portions of the structure occurs,” stated ITD Project Inspector Jack Kelly. “It’s important that motorists not follow their GPS but instead pay close attention to signage which is in place to safely direct motorists through the area.”
Construction is scheduled to finish by late 2020.
Wadsworth Brothers Construction, of Draper, Utah is the prime contractor on this project.
Beginning tomorrow night (Oct. 29) at 10 p.m., a new detour will be in place for motorists heading east on Interstate 84/86 from Burley toward Pocatello. During this time, crews will install new structures to hold overhead signage.
Weather permitting, this temporary traffic pattern is expected to last until 6 a.m. on Wednesday, October 30.
“Unlike previous detours that have been occurring in this area, this portion of construction requires that we direct motorists completely off of the interstate,” said ITD Project Manager Travis Hitchcock. “Directing traffic to Idaho Highway 77 and Idaho Highway 81 will allow for safe installation of the structures without traffic traveling underneath.”
This is part of the Salt Lake Interchange replacement project, underway since May of last year. Construction is scheduled to finish by late 2020.
Drivers should still anticipate reduced speeds through the work zone and pay close attention to signage in place to safely direct motorists through the area.

Traffic will be detoured Thursday, May 30 for motorists heading eastbound on Interstate 84 from Burley toward Pocatello as crews work to complete girder placement on the newly constructed bridge.
This is part of the Salt Lake Interchange replacement project, underway since May of last year. Construction is scheduled to finish by late 2020.
This temporary traffic pattern is expected to be in effect between the hours of 9 p.m. and 6 a.m. while the girders are placed.

Traffic will be detoured overnight next week for motorists heading eastbound on Interstate 84 from Burley toward Pocatello as crews work to place girders on the newly constructed bridge.
This is part of the Salt Lake Interchange replacement project, underway since May of last year. Construction is scheduled to finish by late 2020.
This temporary traffic pattern is expected to be in effect between the hours of 9 p.m. and 5 a.m. during the nights girders are placed. Work is anticipated to be completed within a week.
“Detouring traffic around this portion of the work zone ensures the safety of motorists who would otherwise be traveling underneath the bridge,” said ITD Project Manager Travis Hitchcock. “Crews will be working to place the girders at night in order to reduce traffic impacts during peak traveling hours.”
