Sealcoats for US-12 east of Kooskia begin tomorrow

Picture of US-12 taken from a drone.

Construction will start tomorrow to apply sealcoats to two sections of U.S. Highway 12 east of Kooskia. Sealcoats are necessary applications that will prolong the life of pavement. They improve the driving surface by waterproofing the roadway and increasing skid resistance for safety.

Work will start near the Lochsa Ranger Station at milepost 121 and move toward White Pine River Access. Then crews will shift to Powell at milepost 151 and work toward Lolo Pass at milepost 167. US-12 will be down to one lane with flaggers alternating traffic. Each section is anticipated to take between one to two weeks to complete before crews move on to the next.

Drivers are encouraged to follow all posted work zone speeds and be ready to stop for flaggers. Delays may range from 15 to 30 minutes, and a pilot car will escort motorists safely through the work zone. Crews appreciate the patience of the public during this important preservation work.

Construction will conclude by the end of July. Live traffic impacts across the region can be found by visiting 511.idaho.gov. Travelers can also dial 5-1-1 or download the app.

Repairs on five US-95 bridges north of New Meadows start Wednesday

The Idaho Transportation Department is repairing five bridges along U.S. Highway 95 from New Meadows to Pollock in Adams and Idaho Counties starting Wednesday. Construction on each bridge will last approximately one week, and crews may work on more than one bridge at a time.

The bridges included in this project are the Goose Creek West Bridge, Goose Creek East Bridge, Little Salmon River Bridge, Boulder Creek Bridge and Fall Creek Bridge. View the map to see the exact locations of these bridges. Work will start this week at the Goose Creek West Bridge.

Impacts to traffic will vary by bridge, but overall motorists can expect daytime work with reduced speed limits. US-95 will be reduced to one lane in work zones with flaggers or temporary signals to control traffic.

 

This work is part of a larger effort to repair bridges throughout southwestern Idaho to extend their service life and reduce maintenance costs. ITD is also preforming repairs on bridges in Canyon County

and has completed work on bridges in Elmore and Ada counties.

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.  

Final repairs to US-12 Clearwater Memorial Bridge start Saturday

Picture of the deck on the Clearwater Memorial Bridge on a sunny morning.

Beginning Saturday, traffic on the U.S. Highway 12 Clearwater Memorial Bridge will be reduced to one lane in each direction in preparation for a new surface that will provide a smoother ride for drivers.

Crews will start on the northbound lanes and then shift to the other lanes of the bridge. Each side will remain closed for a few days while crews complete their work. After the new surface is complete, lanes will be striped.

The public should expect minimal traffic delays through the work zone and into next week. Sidewalks will remain open. Crews will work sunrise to sunset.

The work will wrap up before the Fourth of July. Touch up work such as fastening, patching, and painting have been ongoing since the spring. Last winter in 2024, crews finished pouring concrete on the new deck allowing the bridge to be fully opened to traffic.

The newly renovated bridge provides larger travel lanes, shoulders, median and sidewalks. In addition, the construction brought the bridge up to current standards, eliminating weight restrictions for heavy loads that use the bridge daily.

Live traffic impacts across the region can be found by visiting 511.idaho.gov. Travelers can also dial 5-1-1 or download the app.

Repairs to two bridges in Canyon County start Sunday night

CANYON COUNTY – The Idaho Transportation Department will begin maintenance work on two bridges in Canyon County starting Sunday night. Crews will work on both bridges simultaneously with construction lasting approximately one week.

The structures being repaired include the bridge for the eastbound on-ramp that crosses Indian Creek at the Karcher Interchange in Nampa and the Centennial Way Railroad bridge in Caldwell. Work will take place between 8 p.m. and 5 a.m. with speed limits reduced to 35 mph.

At the Karcher Interchange, the on-ramp will be closed. Motorists will still be able to access I-84 by following the signed detour.

At the Centennial Way Railroad Bridge, one lane will be open in each direction.

This work is part of a larger effort to repair bridges throughout southwestern Idaho to extend their service life and reduce maintenance costs. ITD has completed work on bridges in Elmore and Ada counties and will be working on bridges along US-95 in Adams/Idaho counties later this summer.

Repairs will include:

  • Patching and sealing concrete
  • Working on expansion joints
  • Removing asphalt overlays
  • Improving deck drains
  • Milling and paving bridge approaches
  • Painting steel structures

All abuzz and aflutter about Pollinator Week

Traditionally, the third week in June is recognized as Idaho Pollinator Week. The essential partnership between birds, bugs and birds and agriculture and government agencies is celebrated year-round by ITD, though. The week draws awareness to pollinators and spreads the word about how we can protect them.

The agency continually promotes awareness of pollinators and pollinator habitats, Statewide Vegetation Program Manager Cathy Ford said.

“Pollinator species such as birds and insects are increasingly recognized as essential partners to farmers and ranchers in producing much of our food supply. Because Idaho is so agriculturally dependent, that partnership is especially important in the Gem State,” Ford said.

Idaho is home to an abundance of insect pollinators central to the health of our environment. Beetles, flies, wasps, moths, butterflies — but especially bees — all contribute.

Ford also said ITD recently entered into the Monarch CCAA (Candidate Conservation Agreement with Assurances) program. The Rights-of-Way as Habitat Working Group at the University of Illinois-Chicago led a national, multi-sector collaborative effort to develop a voluntary conservation agreement to provide habitat for the monarch butterfly. More than 40 organizations from across the energy and transportation sectors worked together to develop the CCAA that encourages landowners and land managers to adopt measures to create net conservation benefits for the monarch butterfly. The effort is unprecedented in terms of its cross-sector participation and geographic extent. The agreement spans the entire contiguous 48 states and is encompass millions of acres of habitat.

To date, there are 40 energy sectors and 40 transportation agencies who applied for the Monarch CCAA and 66 Certificates of Inclusion issued! Ford said that ITD is among that group! More than 1.2M acres have been adopted. The adopted acres are lands dedicated to promoting habitat by reduced mowing and herbicide treatments, protection of native habitat and monarch host plants, and seeding acres that include a wide range of native plant species. Another way to look at it is the adopted acres are actual acres set aside for monarch habitat (reduced mowing and herbicide treatments, etc.).

Pollinator Partnership celebrates National Pollinator Week by the U.S. Department of Agriculture and the U.S. Department of the Interior. ITD also takes part in partnership projects with the U.S. Fish & Wildlife Service, Idaho Fish & Game, and other state and federal agencies.

Inkom on-ramp to northbound I-15 (Exit 58) night closures planned for next week

Map of detour in construction area around Inkom.

Due to bridge demolition, the Inkom northbound entrance ramp onto I-15 will be closed for two nights. The West Inkom Interchange northbound entrance ramp (Exit 58) closure will take place from 9 p.m. to 6 a.m. on Monday, June 23 and Tuesday, June 24, weather and other factors permitting.

Traffic will be detoured to Old Highway 91 and then to Exit 63 to head north on I-15. Please watch for crews, use caution, and drive safely.

Due to the nature of the work, considerable noise is expected during the bridge demolition.

The Idaho Transportation Department is in the process of replacing bridges on I-15 at Inkom:

  • Over the Union Pacific Railroad tracks and Old Highway 91.
  • Over Rapid Creek Road (Main Street).
  • I-15 bridges and reconstructing the West Interchange.

ITD combined and streamlined the projects to reduce the construction timeline to approximately two years rather than doing one location at a time over three years. This approach minimizes disruption to the local community and the traveling public and efficiently uses construction funds.

To learn more about the project or sign up for construction updates, please visit: itdprojects.idaho.gov/pages/i15-inkom-corridor. This temporary closure and other traffic impacts will be posted to 511.idaho.gov.

Hazard Tree Removal on Idaho Highways

Logs from a hazard tree removal project decked up on the side of the road awaiting removal.

The Idaho Transportation Department would like to share information regarding tree removal along highways in Idaho.

The current tree clearing you may see in various locations along state routes is part of an ongoing hazard tree removal effort as part of our maintenance program to improve safety.

We prioritize removal based on the below safety benefits:

  • Visibility: Clearer sightlines mean drivers can spot wildlife or obstacles sooner.
  • Clear zone: Removing obstacles like trees from the clear zone around highways makes it more likely that any drivers who leave the roadway have a better chance of safely recovering and making it back to the road.
  • Winter driving safety: More sunlight reaches the road surface, reducing icy conditions and the risk of black ice.
  • Roadway safety: Reduces the risk of falling trees on the roadway.
  • Wildfire preparedness: Removing trees near the road creates natural firebreaks that can serve to help slow or stop wildfires.

ITD is not just focusing on tree removal within our own right of way but also proactively engaging other public agency partners, such as the U.S. Forrest Service and Idaho Parks and Recreation, to bring these safety benefits along more of our highways.

In instances where there is a need to address trees on private property we work collaboratively with property owners and get express permission before proceeding with tree removal. We do not remove trees on private land without permission.

It’s also important to understand that not all tree removal you may see along highways is being performed by ITD. Private property owners and timber operations often conduct logging or thinning near roadways, and while we require permits for any work within our right of way that we are not initiating, many of these operations happen entirely on private land.

We understand that Idahoans value our outdoor spaces and the area’s natural beauty. Every decision we make on hazard trees is made with the intent of saving lives.

We’re committed to being transparent about our work and welcome any questions from the public. The public can always reach out directly to ITD for accurate information from district representatives.

Paving begins north of Blackfoot

A dump truck and paver working on repaving a road.

Tomorrow the Idaho Transportation Department will begin repaving the southbound lanes of Interstate 15 from the Rose/Firth Exit 98 to one mile north of West Blackfoot Exit 93. Traffic will be reduced to one lane in each direction and moved over to the northbound side of I-15.

The project will reconstruct the road to address rutting and potholes. Work is anticipated to be completed in mid-August. The northbound lanes were similarly repaved last year.

Motorists should carefully follow signs and posted speed limits while traveling through the construction area and are encouraged to use 511.idaho.gov or the 511 app to keep track of project detours.
