TROY, Mont. — The Kootenai River Bridge along US Highway 2 (US 2), located approximately one-half mile northwest of Troy, will be temporarily closed on June 8 from 11:30 p.m. to 5:30 a.m. June 9. This is the first in a series of seven additional nighttime closures to repair the bridge.

The dates and times of all future closures will be communicated via variable message signs positioned throughout the area. The public can also sign up for text alerts and informational emails communicating future closure dates if desired.

For text alerts, text “Kootenai” to 406-384-9823. For email alerts, email “Kootenai” to brittany.cremer@hdrinc.com.

These closures are part of an ongoing repair project by the Montana Department of Transportation (MDT) and Frontier West to replace existing expansion rocker bearings on piers 3 and 6 of the bridge, in addition to minor repairs to the driving surface and bridge deck.

During each closure, the bridge will not be accessible to the public. Emergency services and first responders will still be able to access the bridge during the closure.

A detour route with a 5-ton weight limit will be maintained (see attached map) during the temporary bridge closures. The detour will bypass the bridge along River Road (Old US Highway 2 South) to Roosevelt Parkway then 3rd Street.

Vehicles hauling trailers and long loads are encouraged to seek an alternate route, as there is a sharp, 90-degree turn along the detour route at the Roosevelt Bridge. Additionally, the project area has a width restriction of 12 feet.

Oversized and wide loads should call MDT Project Manager, Jason Livingston, at 406-471-0233 to coordinate travel across the bridge.

Signalized, single-lane traffic will be in place during normal working hours. Please allow additional travel time and watch for reduced speeds (35 mph) and flaggers in the construction area.

For questions related to the project, please contact Brittany Cremer with HDR Public Involvement at 406-384-9823 or brittany.cremer@hdrinc.com.
