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.

Next Wednesday and Thursday (Oct. 30 & 31) the Idaho Transportation Department is planning to place a bridge deck on the newly constructed Salmon Falls Creek Bridge near Banbury Hot Springs in Twin Falls County.
“While the deck is being placed, motorists will encounter longer than normal delays,” says ITD Project Manager Kenny Lively. “Although most construction delays have been minimal, this upcoming work could result in wait times upwards of 30-40 minutes. As such, we are recommending motorists utilize an alternate route during these days.”
Weather permitting, placement of the deck is expected to take place between 10 a.m. and 3 p.m. each day. In the mornings and evenings, when work is not underway, the area will be open to single lane traffic with a temporary traffic signal in place.
This is part of a larger bridge replacement project that has been underway since June of this year. When completed, the new structure will be both wider and longer – accommodating two 12-foot lanes in each direction, and incorporating a new left-turn lane as well.
Construction on the project is expected to be complete by early summer of next year.
The general contractor is RSCI from Boise.
On Wednesday and Thursday (Oct. 16 & 17) the Idaho Transportation Department (ITD) is planning to close US-20 between mileposts 164 and 173 near Fairfield as crews pave the newly constructed Willow Creek and Rock Creek bridges.
The closure is expected to begin at 11 a.m. and is anticipated to last approximately three hours each day.
This is part of the Willow Creek Bridge and Rock Creek Bridge construction projects underway since April of this year. Crews replaced aging and corroded culverts with new bridge structures, which are expected to have a longer lifespan. It will also allow the streams in both locations to be restored to a more natural condition, which should have a positive effect on the surrounding ecosystem.
“We are making every effort to minimize impacts to motorists in the region,” said ITD south-central Idaho Project Manager Brock Dillé. “With the unexpected drop in temperatures this past month, we have a very narrow window to complete work on these structures. Briefly closing the highway will allow us to work more efficiently, and hopefully prevent us from having to return to the area next year to complete the project.”
ITD will place barricades and signage at area intersections to alert travelers. Flaggers will also be present to inform motorists and assist them with determining the best path of travel.
Knife River is the general contractor for both projects.
The Idaho Transportation Department (ITD) is planning to rebuild the Interstate 84/Idaho Highway 50 interchange in 2024 and is seeking public input on several design options.
ITD will display five proposed designs, including the no-build option, at a public open house on October 15, 2019, at the Rock Creek Fire Department, 1159 Main St. N. in Kimberly. The meeting will be held in an open house format between 5 p.m. and 7 p.m., giving participants an opportunity to attend anytime within the two-hour time frame. Project team members will be available to discuss the project and answer questions about proposed designs.
The interchange is a key agricultural and industrial route for accessing the Magic Valley along ID-50. As the area grows and more commercial and residential development occurs, the interchange will become even more critical to the safe movement of people and goods.
Improvements are needed to maintain safety, improve mobility, and foster continued economic development in the area.

Lane reductions are anticipated next week on the Perrine Bridge as the Idaho Transportation Department moves heavy equipment from one end of the structure to the other. Weather permitting, work is expected to begin Tuesday morning (Sept. 24) at approximately 8:15 a.m.
Crews will first work on the northbound lanes before moving to the southbound lanes. Closures of the right lane will alternate between north and southbound traffic as crews perform work in relation to that direction.
Motorists are encouraged to check 511.idaho.gov for current updates on road conditions and restrictions.
Additional traffic advisories regarding the bridge will be disseminated when impacts are expected.
The Idaho Transportation Department will continue repairs next week on Idaho Highway 75 in Blaine County. Work will occur on two stretches of roadway between River Street and Weyyakin Drive in Ketchum. Additional work will also take place near Hailey.
Weather permitting, crews are anticipated to complete work within two weeks.
“Our goal is to complete repairs before temperatures drop below 30 degrees,” said ITD area foreman Brad Lynch. “The type of work completed in the coming days will be dependent on how much moisture is in the air.
Some areas will require a detour while work is being performed. Traffic control crews may also be utilized on various stretches of roadway. Motorists are advised to exercise caution and follow signs which will be in place to safely direct drivers through the area.
Repairs are expected to take place between 9 a.m. – 6 p.m.
Lane restrictions on the Perrine Bridge are expected to continue through the end of next week, and intermittently through October as crews conduct inspections and maintenance.
Crane operations will require alternating lane closures across the bridge beginning Tuesday, Sept. 24. Motorists are encouraged to slow down and follow signs in the work zone. No full closures are anticipated.
Motorists are encouraged to check the 511 traveler info website at 511.idaho.gov for status updates, as well as conditions and delays.
Due to inclement weather, the traffic detour planned for Wednesday of this week has been rescheduled for the early morning hours of Thursday, September 12. This detour will affect motorists heading eastbound on Interstate 84 from Burley toward Pocatello. During this time, crews will work to place concrete on the deck of the newly constructed steel girder bridge.
Weather permitting, this temporary traffic pattern is expected to be in effect between the hours of 2 a.m. and 7 a.m.

Work is expected to occur this Wednesday, Sept. 11 on the Interstate 84 eastbound 216 on-ramp near Declo. The Idaho Transportation Department will mill off the existing pavement and inlay the area with new asphalt to improve the overall condition of the roadway.
The eastbound 216 interchange on-ramp will be closed while this work takes place. Motorists will need to utilize on-ramp 208 or 211 for eastbound I-84 access near Declo.
Repairs are anticipated to take place between 8:00 a.m. – 5:30 p.m. and be complete within a day.
