Original Story (June 4)
ITD will require overnight closures on Interstate 84 in Nampa next Tuesday and Wednesday nights (June 10 and 11) to place girders on the new Karcher Road Overpass.
- Eastbound I-84 will be closed overnight Monday, June 10. A detour will begin at 10 p.m. Monday and end at 5 a.m. Tuesday, June 11.
- Westbound I-84 will be closed overnight Tuesday, June 11. A detour will begin at 10 p.m. Tuesday and end at 6 a.m. Wednesday, June 12.
Motorists will follow a detour route on Karcher Road both nights. See detour map below.
“ITD will place 10 steel girders over the two nights. Each girder is 136 feet long and weighs approximately 115,670 pounds,” said Alex Deduck, ITD Design/Construction Engineer. “This is no small operation and we appreciate the patience of the traveling public during the detour.”
ITD is replacing the Karcher Overpass to accommodate additional lanes on I-84. Construction to widen I-84 will begin later this summer.

Work is expected to begin Monday, June 10 on Salmon Falls Creek Bridge near Banbury Hot Springs in Twin Falls County. During construction, ITD will replace the US-30 bridge structure, rebuild approaches, and replace associated guardrail. Construction on the project is expected to be complete by next spring.
The current bridge has exceeded its life expectancy. The new structure will be both wider and longer – accommodating two 12-foot lanes in each direction. A left-turn lane will also be added as part of this project.
Traffic on this section of US-30 will be reduced to one lane through the work zone with a temporary traffic signal in place. Motorists may encounter minor delays and are cautioned to watch for crews during working hours – Monday through Friday, 6 a.m. to 6 p.m.
The general contractor is RSCI from Boise.
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.
Drivers should still anticipate reduced speeds through the work zone and pay close attention to signage which will be in place to safely direct motorists through the area.
Wadsworth Brothers Construction, of Draper, Utah is the prime contractor on this project.
Weather permitting, sealcoat work is expected to begin Wednesday, May 29 on Idaho Highway 46 near Buhl (MP 85 – 91). This is the final stage of the US-30 to Ken Curtis Bridge paving project which occurred last year.
Sealcoating is a roadway surface treatment that takes place during the summer months and helps preserve and extend the lifetime of Idaho’s roadways. It also provides a skid-resistant surface for better vehicle traction. The process requires hot temperatures and dry weather for chips to properly adhere to oil that is deposited on the highway.
When the sealcoat is applied, the roadway will be reduced to one lane. Motorists should anticipate short delays and watch for the presence of flaggers or pilot cars.
Chips placed during the sealcoating process have potential to cause windshield damage so drivers are cautioned to slow down and pay attention to reduced speeds and no passing zones throughout the work area. Work is anticipated to be complete within two days.
Construction is expected to begin the last week of April on a portion of US-93 in Lincoln County. The project will involve the addition of northbound and southbound climbing lanes near Notch Butte, south of Shoshone. Work is expected to be complete this coming fall.
“The addition of climbing lanes will allow drivers to safely pass slower vehicles that may be traveling along the elevated stretch of roadway,” said south-central Idaho project coordinator Kenny Lively. “Overall, this project will help improve safety in the corridor for both commercial and passenger vehicles alike.”
Reduced speeds will be in place throughout the project. Drivers should be aware of crews and equipment present during working hours – Monday through Friday, 6 a.m. to 6 p.m.
Western Construction is the general contractor for this project.
The Snake River Bridge will be reduced to one lane beginning Tuesday, April 9 in preparation for rebuilding the bridge.
What to expect at the Snake River Bridge:
- Temporary traffic signals will be placed on both sides of the bridge to direct traffic.
- Motorists should expect delays of up to 15 minutes.
- The speed limit on the bridge will be reduced from 35 mph. to 25 mph.
The lane and the speed reductions on the Snake River Bridge will remain in effect until the bridge rebuild is complete. ITD will begin reconstructing the north side of ID-55 on April 9. Traffic will be switched to the south side of ID-55 in downtown Marsing while crews begin to reconstruct the north side of ID-55.
What to expect on ID-55:
- Work will occur between 4th Avenue and Riverfront.
- Work will occur during daytime hours.
- Temporary traffic signals will direct traffic. Expect delays of up to 15 minutes.
- Driveway access will remain open with brief delays.
Pedestrians are encouraged to use the south side of ID-55.
Weather permitting, road rehabilitation work is expected to begin next week on Idaho Highway 50 from Red Cap Corner north of Kimberly to Tipperary Road near Exit 182. Work will encompass approximately five miles of roadway including the Hansen Bridge.
Traffic on this section of ID-50 will be reduced to one lane throughout the work zone. Pilot cars and flaggers will be present during working hours which is expected to occur seven days a week, 7:00 a.m. – 7:00 p.m. Motorists should anticipate minor delays and watch for reduced speeds and crew members.
Main construction on the project is expected to be completed in May. Additional sealcoat work is scheduled to occur later in the summer.
The general contractor is Knife River from Boise.
The Idaho Transportation Department (ITD) reminds motorists to drive carefully through work zones — for their own safety and the safety of construction workers.
ITD has more than a dozen projects planned this year in District Four. Every project is different in terms of road pattern changes and reduced speed limits.
Each year, ITD draws special attention to safe driving in or near work zones during Work Zone Awareness Week, April 8-12.
The Idaho Transportation Department will begin work Monday (April 8) on replacement of an eastbound bridge deck spanning the North Side Canal on Interstate 84 south of Hazelton (MP 194).
Eastbound and westbound traffic on this portion of I-84 will be reduced to one lane throughout the work zone. The eastbound interstate on-ramp at Exit 194 will also be closed for the duration of this project.
Drivers should expect reduced speeds throughout the work zone and watch for crews during working hours – Monday through Saturday, 7 a.m. – 7 p.m. Work is expected to be completed in June.
The contractor on this project is Knife River of Boise.
The Idaho Transportation Department will begin work April 1, 2019 on two bridge construction projects along US-20. The new crossings will be located over Willow Creek in Camas County (MP 164) and Rock Creek in Blaine County (MP 173).
During construction, ITD will remove aging culverts and surrounding earthwork at both locations, and construct new crossings over the waterways.
“Due to age and corrosion of the pipelines, both culverts are in need of replacement,” said ITD Project Manager Brock Dillé. “We analyzed multiple options regarding these crossings before determining that bridge designs would have the best long term value for both Willow Creek and Rock Creek.”
The structure spanning Willow Creek will be a 170-foot steel girder bridge while the structure spanning Rock Creek will be a 159-foot concrete girder bridge. As an added result of the forthcoming bridge structures, ITD will also be able to restore the streams to a more natural condition, which in turn should have a positive effect on the surrounding ecosystem.
Construction on the crossings will occur simultaneously. Each work zone is anticipated to encompass one mile with approximately seven miles between each site.

Traffic will be reduced to one lane in the construction zone with width restrictions anticipated. Temporary traffic lights will be in place throughout the duration of the project and reduced speed limits will also be in effect.
ITD and the Idaho State Police advise motorists to slow down and pay attention when driving in work zones, where increased speeding fines and other penalties apply. Motorists are encouraged to plan ahead and dial 5-1-1 or visit 511.idaho.gov fo r information on the state highway or interstate system.
Work is expected to last through December.
Knife River is the contractor for both projects.
