Drivers urged to plan ahead as several projects set to kick off on SH-55

SH-55 between Horseshoe Bend and Avimor.

Idaho drivers are urged to plan ahead when traveling north of Eagle this summer as the Idaho Transportation Department (ITD) is advancing several projects along State Highway 55. These projects include lane closures and reduced speeds in various locations between Eagle and New Meadows.

“Each of these projects is intended to improve traffic flow and safety along this regional route. We look forward to a safer, smoother State Highway 55 after these projects are complete,” District 3 Engineer Jason Brinkman said.

The projects include:

  • Little Goose Creek Bridge (Construction: June 2024 – late 2024)

ITD will begin replacing the Little Goose Creek Bridge today along SH-55 near Last Chance Campground in New Meadows. SH-55 will be reduced to one lane in the area with flaggers and a traffic signal during construction. Drivers should expect delays. Learn more and sign up for construction updates on the project website.

  • SH-55 Smiths Ferry to New Meadows chip seal (Construction: July 2024 – fall 2024)

This July ITD will start applying a chip seal to several areas of SH-55 between Smiths Ferry and New Meadows. This project will extend the life of the pavement. The highway will be reduced to one lane with pilot cars where crews are working. Drivers should expect delays. In order to see where crews are working, travelers should sign up for updates on the project website.

  • Rainbow Bridge (Design: 2024-2026)

ITD is currently conducting soil and rock sampling in the area of the Rainbow Bridge for a project to build a new bridge over the North Fork of the Payette River in Valley County. Drivers can expect 15-minute delays on weekdays in June.  To learn more about the project visit

  • SH-55 DMS Sign (Construction: fall 2024)

ITD will install a dynamic message sign on SH-55 between Round Valley and Cascade. The new message board will notify motorists of detours or incidents along SH-55.  Minimal delays expected. Any traffic impacts during the installation will be posted at

  • SH-55 Banks-Lowman Road Intersection (summer 2024)

Flaggers will direct traffic at the Banks-Lowman intersection on all Sundays in July. The project team is planning to install an interim traffic signal at the busy intersection later this year.

  • SH-55 Fleming Creek Bridge Replacement (Construction: fall 2024 – late 2025)

This fall ITD will begin replacing the Fleming Creek Bridge on SH-55 approximately four miles south of Banks. SH-55 will be reduced to one lane in the work zone with speed limit reductions during the week. Details will be posted to later this summer.

  • SH-55 State Street to Horseshoe Bend Rehabilitation (Construction: fall 2023 – fall 2024)

ITD is milling and resurfacing SH-55 between State Street in Eagle and Horseshoe Bend. Work is expected to be complete this fall. Details are available on the project website. Drivers are encouraged to slow down in the work zone as there have been too many close calls with flaggers.
