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.

“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.

Replacement of N Canal Bridge to begin next month in Jerome County

Early November, work is expected to begin on replacing the N Canal Bridge on Idaho Highway 25 east of Jerome. Built in 1956, the current bridge has reached its life expectancy. The new structure will be both longer and wider than the current bridge, and also support heavier load capacities.

“The new bridge will facilitate space for construction of a future pedestrian walkway,” said ITD Project Manager Tom Logan. “It will also allow for existing utilities to be placed underneath the structure.”

As part of the project, the adjacent ID-25 approaches will be brought up to grade as well.

“Updating the grade of the bridge, along with the northbound and southbound approaches, and increasing the width will improve safety for the traveling public,” stated Logan.

During the first phase of construction, the South 100 W approach will be closed with traffic diverted through the Producers Livestock parking lot. The North 100 W approach will then be closed during the second phase of construction.

Traffic on ID-25 will remain open but reduced to one lane in each direction throughout the duration of the project. Barrels will be in place to safely guide motorists through the work zone.

“Most of our work on the bridge must be completed while the canal is dry,” said Logan. “We expect the majority of work to be done by March of next year, with remaining items to be completed by the Spring.”

Coldwater Group, Inc. of Pleasant View, Utah is the primary contractor for this project.

New traffic pattern in place next week at Salt Lake Interchange project

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.

Westbound I-84 on-ramp closure expected next week at Exit 168 in Jerome County

Work is expected to begin next Monday (Sept. 21) on the Interstate 84 westbound on-ramp for Exit 168. This is part of the interstate rehabilitation project that has been underway since May of this year to provide a safer and smoother ride for motorists.

The Exit 168 westbound on-ramp will be closed while crews work on three drainage pipes in the area. Motorists will need to use Exit 165 to access westbound lanes on the interstate.

Message boards and traffic control will be in place to direct drivers. Work is expected to be completed by the end of the week.

“We are nearing the completion of storm water pipework for this project,” said ITD South-central Idaho Project Manager Brock Dillé. “After this is complete, we will begin paving the newly constructed westbound lanes.”

Rehabilitation of the westbound lanes is expected to be complete by the end of this year. Work on the eastbound lanes will begin in the spring of 2021.

The general contractor is Western Construction of Boise.

Crews successfully slide new I-84 bridge into place

demolition of the blacks creek bridge begins

Normally, bridges moving is not something an engineer wants to see, but this weekend construction crews slid the first of two new bridges at the Interstate 84 Blacks Creek Interchange sixty feet into place — where it will stay for decades to come.

The slide-in-place maneuver was designed to minimize impacts to the heavily traveled Interstate. Crews construct the bulk of the new bridge right next to the existing structure. When ready, the old bridge is demolished and the replacement structure is slid into place.

“The driving force behind choosing a lateral bridge slide method was our focus on the people we serve and their ability to get where they need to go.” said Patrick Kelly, the ITD project manager overseeing the work. “We were able to keep lanes open during the entire bridge construction process. Once it was ready, we closed the eastbound lanes, demolished the old structure, pushed the new bridge into place, and are wrapping up construction on the adjacent roadway. In the end, we will have closed interstate lanes of traffic for weeks rather than months.”

The whole process, from demolition to reopening traffic, will take two to three weeks. Normal bridge replacements can take several months. With the new bridge in place, crews have just a few final items to complete, including work at the bridge abutments and repaving approaches.

To get the bridge from temporary footings to its permanent home, crews lay down Teflon pads and cover them with dish soap. Then, heavy machinery pushes and pulls the structure into place. It’s a surprisingly effective way to reduce friction and easily move the massive structure.

“Seeing how smoothly the bridge slid into place was very satisfying.” said Kelly. “It has been months of planning, preparation, and a lot of hard work to get to this point. The crews from Knife River have done a wonderful job and should be very proud of the work they’ve done.”

This method has been used before in the Gem State when, in 2014, the Lardo Bridge on ID-55 in McCall was replaced. There, as it is at Blacks Creek, the highway is an essential connection and lengthy disruptions are very impactful.

The second bridge for the westbound lanes has been constructed next to the old structure. Crews are currently finishing up the eastbound side of the interchange, including work on ramps and Blacks Creek Road. They will be ready to slide the westbound bridge into place in early August using the same method.

Evening traffic on I-84 in Jerome County to experience intermittent delays beginning next week for controlled median blasting

On Monday (July 20) work in the median of Interstate 84 will require traffic to be intermittently delayed. This is part of the interstate rehabilitation project that has been underway since May of this year. Carefully controlled blasting is required to loosen the hard rock in the median.

“We completed crossovers earlier this month and are now moving into the next phase of the project which entails storm water and draining construction,” said ITD South-central Idaho Project Manager Brock Dillé. “This phase of the project requires us to blast portions of the median which will have a short term impact on traffic.”

For the safety of drivers, traffic must be stopped in the surrounding area while blasting is underway.

“There are four locations in the median that we need to address,” stated Dillé. “We expect these activities to take place on various days between July 20 to August 20. Blasting may produce delays for motorists up to 60 minutes although we anticipate the delays to be much shorter.”

In addition to traffic being stopped on I-84, the interstate on ramps at Exit 165 eastbound, 168 westbound and 173 westbound will also be closed while blasting occurs. A portion of the work will require closures on the north and south frontage roads (Bob Barton Road and East Frontage Road) as well.

After each blast, crews will ensure the roadway is safe and free of all debris before reopening the highway to traffic.

Dillé explains that timing of this work is very important. “We have to blast during daylight hours, but we are very conscious of the impact it will have on the traveling public, which is why we are undertaking this task in the evening when traffic on the interstate is past its peak hours.”

Blasting will not begin before 7:30 pm.

ITD is asking motorists to consider using alternate routes while this activity is underway. Electronic message boards and signage will be placed on the interstate several days in advance of each event. Motorists are advised to adhere to signs and pay attention to flaggers and pace cars that will be utilized to slow traffic on the interstate.

Change in traffic on US-93 in Jerome County starting this week

Crews and heavy equipment work along US-93 in Jerome County.

Traffic flow is expected to change as early as Friday, June 19 on US-93 between 200 S Road and 300 S Road in Jerome County. This is part of the ongoing US-93 widening project, which will see the highway transition from two lanes to four to increase mobility and traffic flow in the area.

“We will be placing temporary traffic signals at both ends of the project later this week,” said ITD South-central Idaho Project Manager Sam Purser. “While these signals are in place, crews will tie the newly constructed northbound lanes into the existing highway.”

Temporary signals will be utilized for approximately three to four weeks.

“We are not anticipating any additional intersection closures at this time,” stated Purser. “If we find closures are necessary for safety of the traveling public, we will implement them accordingly.”

Motorists can anticipate minor delays and are encouraged to plan ahead if commuting through the area. In addition to the signals, construction signage, candlesticks, and barrels will also be in place to safely direct those traveling through the work zone.

Drivers are advised to use caution and watch for workers and heavy equipment entering and exiting the highway.

“This project will improve safety at the US-93/200 South intersection for both passenger and commercial vehicles,” explained Purser. “The end result will be a divided highway similar to what drivers encounter two miles south of this area.”

Idaho Materials and Construction is the prime contractor for this project.
