Detour tonight at Fort Hall (Exit 80) Interchange

Fort Hall Construction , I-15, Exit 80

POCATELLO – Aug. 28, 2023 | Southbound drivers on I-15 will be detoured through the interchange ramps at Fort Hall (Exit 80) tonight from 9:30 p.m. to 5 a.m. This will allow crews to operate safely as they work on the bridge beams over the roadway.

The Fort Hall Interchange is undergoing a complete reconstruction to replace the outdated bridge and improve on- and off-ramps. The redesign also allows for the planned three lanes northbound and southbound on I-15. Those wishing to learn more about the project can visit

Motorists should exercise caution while travelling through the work zone as traffic patterns will continue to change over the next week to accommodate construction. Drivers can also check or download the 511 app for the last traffic conditions on all state highways and freeways.

ITD to begin night work in Idaho Falls this week through September

Construction zone Sunnyside to Lomax

The Idaho Transportation Department will begin a resurfacing project August 10 that will last through the end of September on Interstate 15/U.S. Highway 26 from Sunnyside Road to Lomax Street in Idaho Falls.

Crews will first mill or grind down the upper layer of the existing asphalt to remove any cracks, ruts, and imperfections. They will then place a layer of asphalt on top of the milled surface to fill any holes and make a smooth surface. This will help extend the lifespan of the road.

During construction traffic will always remain on a paved surface, and pedestrians will always be able to pass through the work zone.

Work will begin each night at 8 p.m. and last until 6 a.m. Lane restrictions will be in place along with flaggers during work hours. All signals may be off at times throughout construction. Drivers should follow directions from flaggers or treat a red flashing signal as an all-way stop.

For updates on traffic impacts on state highways and interstates, drivers should check before traveling.

Repaving project on US-20 in Island Park

The Idaho Transportation Department will begin repaving on US Highway 20 through Island Park on August 14 and is expected to last until late September.

Repaving will take place on the 17.6 mile stretch of US-20 from Pine Haven Drive North to Island Park Lodge between the hours of 7 p.m. and 7 a.m.

The roadway will be reduced to one lane in alternating shifts to allow traffic flow. During this time there will be flaggers on the road as well as a pilot car to lead traffic approximately two and a half miles each shift. This will continue until the project is completed in late September.

Repaving is important to maintaining the roadways. Heavy traffic takes a toll on both concrete and asphalt, producing ruts and surface generated cracks. Road resurfacing increases the safety of our roadways and contributes to longevity and clarity of road markings.

Drivers are encouraged to obey traffic laws, traffic signs, and construction signs while traveling through work zones.

Leading Idaho funds Rigby Airport Taxiway

Rigby Airport Plane

The latest small community airport in Idaho to benefit from Governor Brad Little’s Leading Idaho initiative is the Rigby Airport. The $373,000 improvements included a new taxiway. Leading Idaho enables the Division of Aeronautics to make these worthwhile projects possible financially.

The Rigby Airport’s economic impact includes 66 jobs, $5.4M in GDP, and $11.5M in total output, according to the 2020 Idaho Economic Impact Analysis Update Report.

“It was imperative that we installed the parallel taxiway in the name of safety and constantly increasing traffic every year as the airport became appealing for a growing and vibrant aviation population,” said Rigby Airport Manager Mike Byers.

Byers added that the new taxiway was a long time coming.

“The taxiway was originally planned to be installed in 1977, but due to budget constraints, we had to shelf the project year after year. Thanks to the Idaho Division of Aeronautics, Rigby airport is now safer and able to bring sustainable growth to the city.”

The new taxiway had been identified again in the airport’s 2010 Master Plan.

As part of Governor Little’s “Leading Idaho” initiative, the 2021 Idaho Legislature dedicated $126 million of one-time funds from Idaho’s budget surplus to transportation projects statewide. The funds were split 60/40 between ITD and local jurisdictions. Construction on this project is paid for with ITD’s portion of the funds that will accelerate projects to replace bridges, restore pavements, and improve mobility in communities across Idaho.

Bridge repairs underway on US-20 in Idaho Falls

Bridge over Riverside Dr. I.F.

Bridge repairs are underway on U.S. Highway 20 in Idaho Falls at the bridge over Riverside Drive.

Eastbound traffic will be reduced to one lane for approximately one week while crews repair the expansion joints.

The speed limit will be reduced to 35 mph.

The lane closure will remain in effect even when crews are not on site to allow the new concrete to cure.

More extensive repairs to the bridge are needed and planned for later this summer.

Idahoans value work zone safety

Cones in truck

The Idaho Transportation Department is joining states across the country for National Work Zone Awareness Week. The national and state campaigns this week are designed to raise awareness and educate the public about the safety measures we can all take in work zones, and how we are all responsible for work zone safety.

From 2017 to 2021, Idaho saw 3,119 crashes in work zones resulting in 36 deaths, stressing the need for this year’s theme: “You play a role in work zone safety. Work with us.”

This special week includes a schedule of activities; everyone is encouraged to go orange for safety on Wednesday and observe a moment of silence on Friday for those who have died in work zones.

“Work zone safety is drivers and highway workers cooperating together to slow down and improve safety,” said Dan McElhinney, Chief Deputy and Chief Operations Officer for ITD. “ITD employees and contractors design traffic control with signs, cones, beacons or reduced speed limits to help guide vehicles through these hazard zones, knowing we really appreciate drivers being engaged without distractions for success. Let’s all get home safely every day.”

Work zone crashes are preventable. The top three causes of crashes from 2017 to 2021 were following too closely, distracted or inattentive driving and failing to yield.

Drivers should:

  • Plan ahead – Check before you go to plan your route. Expect delays, leave early or take an alternate route if possible.
  • Slow down– drive the posted speed limits.
  • Pay attention– both to workers directing you and surrounding traffic.
