Detours planned on I-84 at Exit 208 while crews remove old highway bridge

Temporary detours will be in place this week while crews remove the old State Highway 27 bridge over Interstate 84 near Burley.

Starting tomorrow, I-84 eastbound traffic will be rerouted onto the temporary roadway in the median from milepost 206 to Exit 208. The west and east sides of the SH-27 bridge will be removed during two nighttime closures.

The I-84 westbound lanes will be closed from 6 p.m. on July 31 until 7 a.m. Aug. 1 for the removal of the existing SH-27 structure crossing over the I-84 westbound Lanes. Drivers traveling westbound will be detoured onto SH-27 at Exit 208 and State Highway 25 to the Exit 201 on-ramp to return to I-84 westbound.
The I-84 eastbound lanes will be closed from 6 p.m. on Aug. 1 until 7 a.m. on Aug. 2 for the removal of the existing SH-27 structure crossing over the I-84 eastbound Lanes. Drivers traveling eastbound will be detoured onto SH-27 at Exit 208 and US Highway 30 to the Exit 211 on-ramp to return to I-84 eastbound.

Detour signage will guide motorists through the project area. Detour dates, routes, and times may be impacted by weather or other unforeseen factors. Please watch for crews, use caution, and drive safely.

Construction has been underway since 2024 to update the Heyburn and Burley Interchanges to meet growing traffic demands and is anticipated to be complete in 2026. The project is funded as part of Governor 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.

ITD hosts Snake River Crossing public meeting 

The Idaho Transportation Department invites Magic Valley community members to attend a public meeting on Monday, June 30, to provide input on the Snake River Crossing Project and help review and refine the first phases of analysis and design before the project moves forward. 

During this public meeting, ITD will share study findings, initial concepts and evaluation criteria, project goals, and a range of alternative locations for an additional Snake River crossing. 

“Our shared goal with local and regional partners is to address growing traffic and regional connectivity challenges in the Magic Valley,” District Engineer Jesse Barrus said. “A potential additional Snake River crossing is a key part of reaching that goal, and we look forward to hearing the community’s feedback.” 

In 2024, the Idaho Transportation Board approved funding to begin next steps to enhance Magic Valley regional mobility including launching the environmental review process for a new Snake River Crossing to consider options for an additional bridge crossing, potentially extending State Highway 25 or State Highway 79 or widening U.S. Highway 30 or State Highway 46. 

The project will utilize information gathered from previous studies and include coordination with the new Magic Valley Metropolitan Planning Organization to identify and evaluate feasible, buildable, and fundable bridge alternatives.  

“This public meeting marks a key milestone in the Snake River Crossing project and offers the community a chance to provide input on potential 1,500-foot-long bridge locations,” said Dan McElhinney, the ITD Chief Deputy and Chief Operations Officer. “Taking a major bridge project of this scale from concept to construction will continue to require strong regional collaboration, innovative funding solutions, and long-term commitment.” 

Opportunities to participate are available both in person and online. Both experiences will include the same information and chances for feedback:  

In Person: June 30, 2025, drop in anytime between 4 and 7 p.m., Herrett Center for Arts and Science, 315 Falls Ave, Twin Falls 

Online: June 30 through July 30, 2025, snakerivercrossing.com 

An additional public meeting is anticipated in early fall. For more information, please visit the project website: itdprojects.idaho.gov/pages/snakerivercrossing.  

SH-75 project identified for further funding

Today at its regular monthly meeting the Idaho Transportation Board accepted staff recommendations on priority corridors across Idaho using TECM funds to address congestion, including State Highway 75 north of Hailey. Since Transportation Expansion and Congestion Mitigation funds were first used by the department for bonding and advancing major projects in 2022, ITD has delivered timely construction of expansion projects across the state. Today’s actions are a continuation of that.

Funding came from House Bill 25, which was passed by the Idaho Legislature earlier this year. The legislation provides an additional $20 million a year to the Transportation Expansion and Congestion Mitigation fund for the next three years and allows the department to invest an extra $1 billion in the Idaho transportation system.

With this new funding, SH-75 from McKercher Boulevard to Broadway Run has been recommended for advanced construction. This project will add capacity by widening the road to two lanes in each direction. Safety will be enhanced with a continuous center turn lane and pedestrian/transit improvements. Construction is anticipated to start in 2026, one year earlier than planned.

With this project now included in the draft Idaho Transportation Investment Program (ITIP), the public will have the opportunity to give feedback on this project and the department’s full list of planned projects from 2026-2032 during the annual comment period in July. Then the draft ITIP will be presented to the board for approval in September.

The board’s action today reflects continued investment targeting congestion and capacity in major corridors that were previously funded by TECM bonds as authorized by the Idaho Legislature. In South-central Idaho, TECM funds are funding the widening of I-84 from Jerome to Twin Falls, and full reconstruction of the Burley and Heyburn Interchanges.

This project and others were identified because they are existing high-priority corridor needs that will improve traffic flow and increase safety.

Lane Closures Begin Next Week Near I-84/I-86 Interchange for Chip Sealing

Starting next week, drivers should expect lane closures on Interstate 84 between Malta/Yale (Exit 228) and Idahome (Exit 237) as crews perform chip sealing to preserve and extend the life of the roadway. A short section of Interstate 86 near the interchange will also be included in the project.

Traffic will be reduced to a single lane in both directions during the two-week operation. On- and off-ramps within the work zone will also be chip sealed. While no ramps will be fully closed, half of each ramp will be closed at a time to allow traffic to continue flowing.

Speed limits will be reduced to 55 mph on the mainline and 35 mph on ramps during construction. Drivers are urged to allow extra time and avoid following other vehicles too closely to prevent windshield damage.

For updates, visit 511.idaho.gov.

On-ramp to eastbound I-84 at Burley Interchange to close Monday morning

The on-ramp to head east on Interstate 84 at the Burley Interchange will close for the week starting Monday morning for repaving.

The closure will be in place from 6 a.m. Monday (May 19) to 11 p.m. Friday (May 23). To head east on the freeway, drivers will be detoured to the nearest on-ramp about five miles to the east at the Heyburn Interchange (Exit 211).

Drivers will still be able to head west on I-84 from the Burley Interchange. Traffic on I-84 remains two lanes in each direction, and the speed limit is reduced to 65 miles per hour in the work zone.

Construction has been underway since 2024 to update the Burley and Heyburn Interchanges to meet growing traffic demands and is funded as part of Idaho Governor 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.

April 21–25 is Work Zone Safety Awareness Week

Drone shot of the Heyburn Interchange on I-84 before construction

As construction season ramps up across the state, the Idaho Transportation Department is joining transportation agencies nationwide in recognizing Work Zone Safety Awareness Week, April 21–25. This annual effort is a timely reminder to Idahoans that driving safely in work zones protects everyone on the road, including the crews working alongside fast-moving traffic.

“Driving cautiously in work zones helps families,” said Dan McElhinney, ITD Chief Deputy and Chief Operations Officer. “Travelers, workers, and their loved ones all benefit when drivers reduce crash risks by driving slower and staying alert for traffic cones and guiding signage. Our employees are working hard to improve roadways and quality of life for Idahoans. Driving safely near road work is one of the best ways to support that effort.”

Work zones are active job sites where ITD crews, contractors, utility workers, law enforcement, and tow truck operators are performing critical maintenance and construction—often in unpredictable conditions. These areas are marked by signs, barriers, cones, and sometimes narrowed lanes or uneven surfaces. Rear-end crashes are the most common type of work zone collision, typically caused by distracted or impatient driving.

From 2019 to 2023, Idaho saw more than 3,400 work zone crashes, with 30 fatalities, all of whom were vehicle occupants. This stark reality is often overlooked: drivers and passengers are most at risk in work zone crashes, not just road workers.

To stay safe in work zones, ITD urges drivers to check Idaho 511 before traveling, slow down, stay alert, avoid distractions, and maintain safe following distances, especially around large vehicles. Always watch for workers and flaggers, buckle up, and follow Idaho’s Move Over Law when passing emergency or response vehicles with flashing lights.

In the Magic and Wood River Valleys there are several construction zones ongoing or planned. Drivers should be aware of the following areas:

Burley/Heyburn Interchanges

South Jerome Interchange

SH-75 Elkhorn

Respect the zone so we ALL get home.

For updates and more information, visit Idaho 511 or itd.idaho.gov.

Construction begins on SH-75 in Ketchum

The Idaho Transportation Department will begin construction next week to improve safety and capacity on State Highway 75 between Elkhorn Road and River Street. Construction is expected to be completed in late 2026.

Crews will remove trees in select locations the week of April 28. Generally throughout construction, motorists can expect:

The speed limit on SH-75 will be reduced to 25 mph in the construction zone.
Work will occur Monday – Saturday between 7:30 a.m. – 7 p.m. with the occasional exception on nights and weekends.
One lane will remain open in each direction on SH-75 between Elkhorn Road and River Street.
Closures will occur on local roads, and detours will be in place.
Traffic shifts will occur on SH-75 and local roads.

SH-75 is the primary north-south highway in the Wood River Valley serving the cities of Bellevue, Hailey, Ketchum and Sun Valley in Blaine County. Improvements include widening SH-75 to 4 lanes between Elkhorn Road and River Street, improving intersections and local roads and making pedestrian access more readily available in the project area. These changes have been developed to accommodate traffic projections for the next 20 years.

The project team will share information about upcoming traffic impacts through email and website updates. For more details and to sign up for construction updates, please visit the project website at itdprojects.idaho.gov/pages/idaho75, email info@sh75project.com or call (208) 254-0421.
