Several sections of State Highway 21, State Highway 75, State Highway 24, State Highway 81, and State Highway 77 will begin receiving surface treatment as early as Monday. Seal coating will begin in Stanley and move through the Wood River Valley for about a month. The sections listed below are in the order that work will be performed:
- Stanley SH 21 for .41 miles
- Galena SH 75 for 11.56 miles
- Ohio Gulch SH 75 2.82 miles
- SH 24
- SH 81
- SH 77
Lane closures will be in effect while crews work on each section. A pilot car will be in place to guide traffic. Drivers should expect delays and consider alternate routes when available.
Seal coating helps extend the life of pavement, reduce the amount of damage done by weather and give a water-resistant surface.
Work should be completed by the beginning of September. For live traffic updates go to Idaho 511
The Idaho Transportation Department will have daytime ramp closures at Exit 141, both on and off ramps, for up to two weeks during work to rehabilitate the pavement on US-30. Closure of the ramps will ensure the work is completed more efficiently and for the safety of the work crews.
During the daytime ramp closures at Exit 141, all drivers will be detoured to Exit 137 about four miles west of Bliss. Ramps at Exit 141 will be opened as work concludes each day; impacts are expected to be complete by July 29.
The ramp closures are part of a project to extend the life of US-30 through Bliss by recycling the existing asphalt, adding cement to better stabilize the roadway base, and repaving the roadway. Construction on US-30 through Bliss is expected to be completed in early fall.

Motorists should watch for new traffic patterns on State Highway 27 as part of the reconstruction of the northbound lanes and bridge over Interstate 84 at the Burley Interchange. Beginning tomorrow, the Idaho Transportation Department will implement the following changes while the new road and structure are under construction:
- Northbound and southbound SH-27 traffic will shift to the west.
- The I-84 westbound on-ramp to SH-27 will be shifted to the north.
- The westbound I-84 on-ramp will be closed on the west side of SH-27.
- The on-ramp located on the east side of SH-27 will provide westbound access to I-84. The on-ramp will be controlled by a temporary traffic signal.
Motorists should slow down and follow construction signage in the work zone to adjust to the new traffic pattern which will be in place until fall 2025.
Reconstruction of the Burley Interchange is expected to cost $85.1 million.
Built in the early 1960s, the interchange has reached the end of its service life. ITD is focused on improving safety, mobility, and economic opportunity for all users who travel this important agricultural and industrial route.
Construction is being funded as part of Idaho Governor Brad Little’s Leading Idaho transportation funding initiative. The Leading Idaho initiative allows ITD to take a deliberate approach to advance large projects that will enhance safety, improve mobility, further strengthen Idaho’s economy, and positively impact the Magic Valley and communities across the state for years to come.

US-93 will be reduced to a single lane on July 23 and 24 for shoulder work from 8 am to 5 pm. The closure will start north of the blinking light at the State Highway 25 junction and last about 2 miles. A pilot car and traffic control will be in place to help navigate through the area.
SH-25 is not expected to be impacted as the shoulder work begins north of the junction. Delays are expected and drivers should try to find an alternative route. Drivers along US-93 will be stopped for a short period of time to allow the flow of traffic on that single lane in each direction with the help of a pilot vehicle.

An emergency repair on Interstate 84 near the Salt Lake City Interchange will begin on July 17 to fix concrete pavement that is starting to fail. The pavement has lifted several inches causing a noticeable bump near one of the bridge decks through the region. This bump can be not only disruptive to motorists but poses a safety hazard.
Westbound traffic will be reduced to one lane and the speed limit has been reduced to 55 mph. Bump warning signs have been placed until the repair can be completed. The repair should take 5 days. Drivers should properly secure loose items on their vehicles, slow down and use extra caution through the area.

The Idaho Transportation Department (ITD) will close the westbound on-ramp (heading toward Boise) at the I-84 South Jerome Interchange (Exit 168) on Tuesday, May 28. The ramp will remain closed for a few months while crews build the new westbound on-ramp.
Traffic will be detoured to the Main Street/Highway 25 Interchange (Exit 165). Motorists will be directed north on S Lincoln Avenue, west on W Avenue D, north on S Birch Street and west on W Main Street/Highway 25. Click here to see a detour map.
Motorists can continue to expect intermittent local road closures, I-84 lane closures, traffic shifts and ramp changes throughout the duration of the project. Construction is anticipated to be completed in 2026.
Details about the I-84 South Jerome Interchange project are available at itdprojects.idaho.gov/pages/sjeromeic or by texting 84JTF to 1-866-483-8422.
Drivers should check 511.idaho.gov before traveling to plan for impacts from this project and other work zones.
The Idaho Transportation Board approved a resolution today to begin next steps to enhance Magic Valley regional mobility including consideration of a third Snake River crossing near Twin Falls.
ITD was approved to utilize up to $9 million to initiate recommendations presented based on a feasibility study developed with stakeholder interviews, traffic evaluations, design reviews, and close coordination with the Third River Joint Powers Board, the city of Twin Falls, and the Magic Valley Metropolitan Planning Organization.
ITD Chief Deputy Director Dan McElhinney stated, “It takes strong regional partnerships that are united and persistent to bring a major bridge project to reality. All are here today in teamwork with ITD. There are significant, complicated environmental and design work ahead that will likely require creative funding solutions partnering over the next few years.”
The Snake River Crossing project will follow the National Environmental Policy Act procedures over the next two years with ITD engaging many stakeholders, initiating field studies and preliminary design on alternatives to consider. Once a NEPA document is complete a preferred alternative can be selected, as efforts continue to identify funding for construction.
In addition to the potential for a new bridge over the Snake River, the process will include consideration of other improvements to ease congestion and enhance connectivity, such as:
- Widen existing bridges on US-30 and SH-46.
- Extend SH-79 or SH-25 south of Jerome across the canyon to US-93.
Other projects will also move forward, including:
- Widening or replacement of the SH-50 Hansen Bridge and widening five miles of SH-50.
- Traffic mobility improvements to the intersection of US-93 (Pole Line Road) and Blue Lakes Boulevard.
ITD District 4 Engineer Jesse Barrus said, “All of these near and long term improvement considerations will help provide this growing region with important mobility alternatives as our existing transportation system continues to experience more traffic demand.”
The Ohio Gulch traffic signal on State Highway 75 was completed and activated on April 11. Over the past several weeks, the Idaho Transportation Department has gathered data to help refine the timing plan of the signal in both directions.
Feedback provided by the community helped pinpoint specific issues drivers experienced and assisted ITD in adjusting the signal timing plan which we expect to result in a reduced wait times and less congestion on SH-75.
ITD will continue to monitor the signal and make any additional adjustments as needed.
