I-84 eastbound lane closure Tuesday at Gowen Road exit for bridge repair work

Graphic map showing I-84 interchange with local road. The area of I-84 over the road is highlighted indicating the construction area.

The Idaho Transportation Department will close a single lane on Interstate 84 eastbound at the Gowen Road exit from 8 a.m. to 5 p.m. Tuesday to complete bridge repair work, weather permitting. 

Work is required to be done during the day due to temperature requirements to effectively apply repair materials. A single lane will remain open, with traffic alternating between lanes as needed throughout the work period.  

Work on the bridge was completed overnight earlier this summer. This daytime closure will allow ITD crews to finish the remaining repairs and restore the structure to full service. 

Drivers should expect delays and are encouraged to plan ahead. For the most current traffic updates, visit 511.idaho.gov or download the ITD 511 app. 

 

Lane and sidewalk closures on Eagle Road starting Monday

Construction equipment installs a variable speed limit sign along a roadway, with the speed display panel visible.

Starting Monday, the Idaho Transportation Department will be working along Eagle Road between Chinden Boulevard and Ustick Road to work on underground utilities for the installation of variable speed limit signs.  

Motorists can expect lane closures from 10 p.m. to 6 a.m. until Dec. 10. Pedestrian traffic will be detoured to alternate routes along Eagle Road, Chinden Boulevard, and McMillian Road for daytime sidewalk and shoulder closures. 

This work is part of the on-going effort to improve safety on Eagle Road. These variable speed limit signs will provide speed feedback for drivers and reduce speed limits during peak traffic times. The signs are expected to be operational within the next few months.

ITD begins 2 week project to resurface the Flying Wye

Cones in truck

Starting Monday the Idaho Transportation Department will begin a two-week project to micro mill and re-paint the Flying Wye connector linking Interstate 84 and Interstate 184.

This work will take place in two phases:

Phase 1: Nighttime micro milling

Between 10 p.m. and 5 a.m. crews will remove the top layer of pavement overnight to reduce impact on daytime traffic. Drivers should expect lane reductions each night during this phase.

Phase 2: Daytime striping

Striping will then occur during the day when warmer temperatures are required for the paint to adhere to the roadway properly. Lane closures will continue as crews install new markings across the bridge.

Motorists are encouraged to plan for additional travel time and check 511.idaho.gov or the Idaho 511 mobile app for the most current traffic impacts, lane closures and travel conditions throughout the project.

Input sought on long-range planning for transportation in Idaho

People review a map of a proposed project

The Idaho Transportation Department is seeking input on long-range planning for transportation across the state through a series of public meetings in the next month.  

Comments will inform the update to ITD’s Statewide Long-Range Transportation Plan, a federally required strategy document that is updated every five years and is used by the Idaho Transportation Board and planning staff as a guide to program future studies and projects.  

Open houses will be held in each region of the state:   

  • Nov. 18 in Pocatello at the Portneuf Medical Center (777 Hospital Way) 
  • Nov. 19 in Idaho Falls at the Crosspoint Community Church (1900 Grandview Drive) 
  • Dec. 2 in Coeur d’Alene at the Hampton Inn and Suites (1500 West Riverstone Drive) 
  • Dec. 3 in Lewiston at the Lewiston Community Center (1424 Main Street)  
  • Dec. 4 in Boise at Mountain View High School Library (2000 South Millennium Way) 
  • Dec. 8 in Twin Falls at the College of Southern Idaho (315 Falls Avenue)  

All events will take place 3 – 7 p.m. The same material will be shared online, with comments sought from Nov. 18 to Jan. 10. 

ITD’s Long-Range Transportation Plan will look at the needs of the transportation network out to 2050 and consider a variety of factors including growth, travel demands, land use, safety, economic development, system reliability and anticipated revenue.  

“This policy document looks at current conditions, existing plans and future trends in Idaho and lays the foundation for ITD to continue to deliver on our mission of safety, mobility and economic opportunity,” said Amy Schroeder, the division administrator for planning. “It’s not necessarily about identifying specific projects. It’s about determining, through data analysis and public input, the best strategy for investing in the transportation system given the variability of future revenue.”  

The plan comes at a time of extraordinary growth and funding uncertainty. Besides seeking public feedback, ITD is engaging with other planning organizations as the plan will look at the transportation network as a whole, which extends beyond state-managed highways to locally owned routes and alternative modes of transportation.  

“This is about working with local jurisdictions and planning agencies to address congestion in major cities,” Schroeder said. “It’s also about adopting a statewide perspective and recognizing that it’s just as important to look at improving safety and reducing fatalities in our rural areas.”  

An additional public comment period to review the draft plan is planned for summer 2026, and the plan is expected to be released in 2027.  

Culvert repairs begin Nov. 13 on SH-45 in Nampa

View looking down a busy commercial street with cars driving in both directions. A sidewalk runs alongside the road with fall-colored trees. Visible businesses include Arby’s on the left and Subway on the right. The sky is clear and blue.

The Idaho Transportation Department will begin roadside work Nov. 13 to repair the Elijah Drain culvert beneath State Highway 45 (12th Avenue) near West Dewey Avenue.

SH-45 will remain open throughout construction. Traffic impacts are not expected until mid-December when crews start working along the shoulder. Drivers should expect short lane shifts or brief flagging operations as needed. Most traffic impacts will occur at night to reduce delays for daytime travelers.

Nearby businesses will remain open and accessible during construction, and no driveway closures are planned.

The work will protect the roadway structure and ensure SH-45 continues to serve the growing Nampa community safely. Construction is expected to continue through spring 2026.

Drivers should watch for crews and equipment, obey posted signs, and slow down when traveling through the work zone.

New digital sign on SH-55 to improve communication

Graphic showing a State Highway 55 road sign with a white background and black outline. The sign reads “Idaho 55” with the state shape and shield design typical of Idaho highway markers.

Drivers on State Highway 55 should expect short delays Wednesday as the Idaho Transportation Department installs a new digital message sign in Round Valley.

A crane will be on site beginning at 10 a.m. and continuing through the afternoon to set the overhead sign structure at milepost 102 just south of Cascade near the descent toward Rainbow Bridge.

During installation, crews will reduce SH-55 to a single lane with alternating traffic. A full closure of up to 15 minutes may be needed while the structure is lifted into place to keep travelers safe from the suspended load.

The new sign will make SH-55 safer by providing real-time alerts about wildfires, delays, and other emergencies along one of Idaho’s busiest mountain corridors. Limited cell service in the canyon makes roadside communication especially valuable for drivers. Drivers can expect the sign to be operational by the end of the year.

Motorists should slow down, follow flagger directions, and watch for crews and equipment in the area.

The image shows a major intersection where crews are building an overpass or interchange, with heavy equipment, cranes, and dirt embankments visible on both sides. Traffic cones line the crossroad, and nearby fields and a few buildings stretch into the distance under a clear blue sky.

The Idaho Transportation Department advises motorists to prepare for nighttime closures over the next month on Franklin Road between Star and McDermott roads as crews place eight steel girders for the future State Highway 16 and Franklin Road Interchange. The girders are horizontal support beams for the bridge, estimated to weigh approximately 184,000 pounds each and will be installed in parts throughout the month of November.

Motorists can expect:

  • Franklin Road will be closed at night from 8 p.m. to 8 a.m. from Star to McDermott roads.
  • Closures will begin Saturday, Nov. 8, and will take place throughout the month.
  • Traffic will be detoured to Cherry Lane.

When complete, the Franklin Road Interchange will allow through traffic on SH-16 to travel over Franklin Road without stopping. The SH-16 and Franklin Road Interchange is expected to open with the entire SH-16 corridor in 2027.

For more information and to sign up for email or text updates visit itdprojects.idaho.gov/pages/sh16corridor or call 208-334-8008.

Drivers are encouraged to plan extra time when traveling through the area at night and check 511.idaho.gov or the 511 mobile app for the latest updates on restrictions and delays.

SH-16 to fully close this weekend between SH-44 and US-20/26

Aerial view of an active highway construction site with multiple excavators, loaders, and work trucks operating on a large dirt area. Crews wearing safety vests work near a newly installed concrete box culvert. Construction materials, trailers, and equipment are scattered around the site. In the background, vehicles travel along a nearby highway, and autumn-colored trees and residential buildings border the work zone under clear blue skies.

State Highway 16 will be fully closed south of State Highway 44 the weekend of Nov. 7-10 as the Idaho Transportation Department installs a drainage structure underneath the highway. SH-16 will be closed between SH-44 and US-20/26. Traffic will be detoured to Star and Linder Roads.

Closures will begin at 9 p.m. Nov. 7 and will end at 5 a.m. Nov. 10. Work will result in significant noise during this time.

Crews will install a drainage structure, also called a box culvert, underneath SH-16. The structure will be 495 feet long and comprised of 86 individual pieces, each measuring 8 feet wide by 6 feet tall and weighing an average of 22,500 pounds.

The culvert is being installed as part of the work on the future SH-16/SH-44 Interchange, which will connect SH-16 to Interstate 84. The new SH-16 corridor is on track to open in 2027.

Motorists are encouraged to text HIGHWAY16 to 1-866-483-8422 for email or text alerts. For maps and details about the project, please visit itdprojects.idaho.gov/pages/sh16corridor.
