Ahead of constructing additional lanes on Interstate 84 in Canyon County, the Idaho Transportation Department is reconfiguring westbound lanes of the Interstate near the Franklin Blvd. interchange.
Currently, three westbound lanes are reduced to two lanes with the far left lane merging into the center lane. In the new configuration, the left lane will no longer merge, remaining a travel lane. The far right lane will end, used as the off-ramp to Franklin Blvd. A similar configuration is on westbound I-84 at the Garrity Blvd. interchange, where the Interstate is reduced from four to three lanes.
“This reconfiguration maintains the existing capacity of I-84 during construction,” said ITD Project Manager Styles Salek. “With this change, we remind motorists to slow down, plan ahead and pay attention in construction zones.”
In order to promote the safety of motorists and construction crews, ITD has partnered with the Idaho State Police to provide enhanced patrols throughout the duration of the project.
This change will allow crews to begin adding lanes in the I-84 median between Karcher/Midland and Franklin Boulevard. The addition of lanes is part of the ongoing I-84 corridor project from Nampa to Caldwell. Improvements are expected to improve safety, address congestion and benefit the regional economy for many years.

The Idaho Transportation Department is issuing a travel advisory on Idaho Highway 55 near Marsing for July 3, 2019.
Construction to rebuild ID-55 through downtown Marsing and the bridge over the Snake River will impact travel around the City of Marsing’s annual July 3rd Fireworks Extravaganza at Marsing Island Park. Traffic will be reduced to a single lane on the highway north of the bridge and in town. No left-turns will be allowed in town during the event.
The Snake River Bridge is closed to pedestrians and bicyclists. The City of Marsing has arranged for a free shuttle service to and from the event. Please see the event map below for details.
ITD encourages those planning to attend the event consider using U.S. 95 to reach Marsing. Consider carpooling to alleviate congestion as over 5,000 visitors are expected to arrive for the celebration. Plan extra time for the return trip. Please exercise patience and kindness as you leave.
ITD reminds those who will be drinking during the event to make a plan in advance to get home safe. The Department is partnering with law enforcement to increase DUI patrols during the Fourth of July week.
UPDATE (June 11)

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.

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.
