Beginning Friday, the Idaho Transportation Department will begin nighttime lane closures on State Highway 44 between Linder Road and State Highway 55 (Eagle Road) for resurfacing.

Resurfacing serves to improve ride quality for drivers and extend the life of the roadway.

Work is scheduled to take place overnight during the following hours:

• Monday through Friday: 9 p.m. to 6 a.m.
• Saturday: 9 p.m. to 8 a.m.
• Sunday: 9 p.m. to 9 a.m.

Flaggers will be on site to guide traffic through the work zone. Drivers are encouraged to slow down, follow posted signs, and plan ahead.

Starting Friday, the Idaho Transportation Department will begin one week of nighttime closures on eastbound Interstate 84 near Gowen Road. The closures are part of a repair project to fix bumps in the roadway caused by settling and rutting at the beginning and end of the bridge.

During the closures, eastbound drivers will be detoured off I-84 at the Gowen Road off-ramp and directed back onto the interstate via the on-ramp. The detour will remain within the same interchange, and only minor delays are expected.

The project involves reconstructing approximately 250 feet of the two-lane eastbound approach before the Gowen Bridge, as well as 50 feet beyond it.

Full eastbound closures are scheduled during the following hours, weather permitting:

• Monday through Friday: 7 p.m. to 4 a.m.
• Saturday and Sunday: 7 p.m. to 7 a.m.

Drivers are encouraged to plan ahead and allow extra time when traveling through the area. For the latest construction updates and detour information, visit 511.idaho.gov or use the Idaho 511 app.

Interstate 84 will be closed in both directions under the Karcher Interchange Wednesday night from 10 p.m. to 5 a.m. This closure will allow crews to safely pour the concrete that will support the third westbound lane on Karcher Road (State Highway 55).

To follow the westbound detour:

1. Exit I-84 at the Northside Interchange (Exit 35).
2. Travel north on Northside Boulevard.
3. Turn left onto Karcher Road.
4. Travel west until you reach the Karcher Interchange westbound on-ramp.
5. Use the Karcher Interchange westbound on-ramp to merge back onto westbound I-84.

To follow the eastbound detour:

1. Exit I-84 using the Karcher Interchange eastbound off-ramp (Exit 33).
2. Cross Karcher Road.
3. Use the eastbound on-ramp to merge back onto I-84.

These improvements are part of a larger effort to improve traffic flow and safety in the area.

Project improvements include:

• Adding a free running right-hand turn at the westbound off-ramp
• Paving a third westbound lane on Karcher Road from the westbound off-ramp to Sundance Road
• Reinforcing the Karcher Interchange and Indian Creek Bridges to support the new lane
• Updating signal equipment and adding a pedestrian flashing beacon at the eastbound on-ramp
• Building a separated mixed-use path on the north side of Karcher Road

The I-84, Karcher Interchange project will enhance safety and reduce congestion at the interchange and along Karcher Road in Nampa. Construction is expected to be completed in the fall of 2025.

Beginning Monday, the Idaho Transportation Department will permanently close three left-turn locations on Eagle Road (State Highway 55) between Interstate 84 and State Highway 44 (State Street) as part of a pilot project to improve safety along the corridor.

The changes are based on traffic safety data and community input gathered during a recent safety study. By reducing conflict points these adjustments are expected to lower crash rates along one of Idaho’s busiest highways.

Left turns will be removed at the following locations:

• The two-way left turn between Island Woods Drive and the north channel of the Boise River
• Northbound left-in at Baldcypress Street
• Southbound U-turn at Bourbon Street near Ustick Road

Later this year, ITD will also install variable speed limit signs between Franklin Road and Chinden Boulevard. These signs will reduce speed limits to 45 mph during peak congestion. Additional improvements will include speed feedback signs and signs warning of stopped traffic at key locations.

“These Highway 55 operational changes reflect a commitment to safety for the more than 50,000 drivers daily, by listening to public feedback and studying crash trends, we’ve identified ways to reduce risk for everyone traveling this 7-mile corridor,” Dan McElhinney, ITD Chief Deputy and Chief Operations Officer said.

Microsurfacing maintenance

In addition to the safety upgrades, ITD will begin microsurfacing Eagle Road from SH-44 (State Street) in Eagle to I-84 in Meridian on Monday. Microsurfacing is a preventative pavement sealcoal that extends the life of the roadway and reduces the need for more extensive repairs.

Construction will begin at I-84 and progress north to SH-44. All work is expected to be completed by late September.

During construction:

• All lanes will be open during the day
• One lane will be open in each direction at night
• Nighttime work runs from 10 p.m. to 5 a.m.
• Drivers may encounter rough surfaces and loose gravel during the day. Please use caution.

“Crews will work one section at a time,” ITD Project Manager Josh Nisson said. “Drivers may see rough surfaces during the day until crews are able to finish that section at night. We appreciate the public’s patience during this project.”

The Idaho Transportation Department will close alternating eastbound and westbound ramps at the Interstate 84 Meridian Interchange (Exit 44) overnight from Saturday to Friday as crews apply a hot chip seal to extend the life of the pavement. Through traffic will not be affected.

Ramp closures are scheduled as follows:

• Saturday and Sunday: Midnight to 5 a.m.
• Monday through Friday: 10 p.m. to 5 a.m.

During these hours, Northbound ramps will be closed Saturday, Wednesday, Thursday and Friday, while Southbound ramps will be closed Sunday, Monday, Tuesday and Wednesday.

ITD is committed to minimizing disruptions during construction while prioritizing the safety of both motorists and crews. Chip seal oil is extremely hot. Drivers are urged to use extra caution in the work zone, stay clear of paving equipment, and follow all posted signs and flaggers’ directions.

The Idaho Transportation Department will begin construction Monday to repair significant barrier damage on the Interstate 184 Flying Wye flyover and westbound Interstate 84.

The damage was caused by a recent crash and presents a safety hazard to motorists. Contractors will restore the bridge barriers, which are designed to contain vehicles during collisions, protecting both traffic on the flyover and traffic below on I-84.

Drivers should expect:

• Intermittent nighttime two-lane closures on westbound I-84
• A single-lane closure on the flyover for approximately two weeks
• Reduced speeds in the work zones

Motorists are advised to plan ahead, allow extra time, and drive with caution through the work zone. For real-time traffic updates and road conditions, visit 511.idaho.gov or use the Idaho 511 app.

The Idaho Transportation Department will install a new Dynamic Message Sign tomorrow in Round Valley to enhance safety and improve communication for drivers traveling along State Highway 55 between Boise and McCall.

The new sign will be located on the southbound side of SH-55 at milepost 102, just before drivers descend toward Rainbow Bridge and enter the narrow canyon stretch of highway.

The sign will display real-time alerts about wildfires, traffic delays, and other emergencies that may impact travel through the corridor. SH-55 is one of Idaho’s most heavily traveled mountainous highways, especially during summer and holiday weekends. Limited cell service in the area makes timely roadside messaging essential.

“Reliable communication in this area is critical, especially during wildfire season or major traffic incidents,” said ITD Project Manager Javier Hernandez. “This new DMS will allow us to give travelers accurate, up-to-date information when they need it most.”

Installation is scheduled to begin tomorrow and will take several days to complete. A single-lane closure will be in place during work, with flaggers directing traffic. Minimal delays are expected.

As part of the project, crews will also install a 50-foot camera pole aimed at the new DMS. This camera will allow ITD to remotely monitor, test, and verify the sign’s performance, helping ensure it’s working properly without needing to send maintenance crews to the site.

Before heading out, motorists are encouraged to visit 511.idaho.gov or use the Idaho 511 app for the latest travel conditions.

The Idaho Transportation Department will begin construction next week for a new interchange at State Highway 16 and State Highway 44 in Star. The interchange will replace the existing intersection.

Initial activities will include setting up temporary traffic control and shifting traffic north to SH-44.

Motorists can expect:

• At least one lane of travel will remain open in each direction of SH-16 and SH-44 during most of the construction.
• Some work will require flagging, delays and occasional detours on SH-16 and SH-44.
• Most work will occur during the day, but some work will be necessary at night.
• Speed limits on SH-16 and SH-44 will be reduced.

The SH-16 and SH-44 Interchange is part of the long-term vision for SH-16. When complete, SH-16 will be a limited-access freeway between Interstate 84 and SH-44. Motorists will use interchanges to enter or exit the highway at I-84, Franklin Road, Ustick Road, US-20/26 and SH-44.

To request email or text alerts, text HIGHWAY16 to 1-866-483-8422. For maps and details about the project, visit itdprojects.idaho.gov/pages/sh16corridor.

Interchange construction is expected to be completed in 2027.

The Idaho Transportation Department and the City of McCall invite the public to provide input on potential improvements to State Highway 55 and Deinhard Lane to Boydstun Street.

SH-55 is part of the primary north-south corridor connecting Boise and central Idaho. Through downtown McCall, SH-55 functions as the city’s “Main Street.” Growth and increasing traffic through downtown have placed pressure on the route’s function as an efficient state highway.

This project focuses on determining the proper use of each roadway and designing improvements accordingly. One potential solution includes exchanging the ownership and classification of SH-55 and with Deinhard Lane to Boydstun Street, reducing traffic in downtown McCall.

The public meeting will be available both in person and online:

• In-person: Wednesday, August 6, drop in anytime between 4 to 7 p.m. at the McCall Public Library, Community Hall, 218 Park Street
• Online: A self-guided website will be available August 6–20 at sh55deinhard-boydstun.com

 

Community members are encouraged to review concept designs, ask questions, and provide feedback.

“Public input is key to ensuring proposed improvements meet the needs of McCall residents, businesses, and visitors,” Project Manager Wendy Howell said. “We encourage everyone to participate, either in person or online.”

The same meeting material and survey will be presented in person and online. While comments are welcome throughout the project, they are most useful if received by Wednesday, August 20.

Stay updated on the project and submit comments at sh55deinhard-boydstun.com.

The intersection of State Highway 55 (Karcher Road) and 10th Avenue in Caldwell will be fully closed from 10 p.m. Friday to 5 a.m. Monday.

Crews will be installing a new waterline for Falcon Ridge Elementary School, which is opening this year. The work requires digging an 18-foot-deep trench across the intersection. Crews will remain onsite throughout the weekend.

Drivers are encouraged to detour around the closure using Interstate 84, State Highway 19, and State Highway 95. Signs will be posted indicating the detour route, additionally drivers can find the detour route at https://itdprojects.idaho.gov/pages/55farmway. Drivers should check 511.idaho.gov before traveling, plan ahead, and allow extra time.

This work is part of the larger SH-55: Farmway Road to Middleton Road improvement project, scheduled for completion in fall 2027. Project improvements include:

• Widening SH-55 to four lanes with dedicated turn lanes
• Installing a raised median from 10th Avenue to Middleton Road
• Constructing detached pedestrian and bicycle pathways on both sides of the highway
• Building a pedestrian undercrossing near Vallivue Middle School
• Upgrading signal equipment at major intersections

The project is designed to improve safety and mobility along the SH-55 corridor in Canyon County. To learn more, sign up for updates, or contact the project team:
