Interstate 90 near Crow Agency has reopened to single-lane traffic in both directions, the Montana Department of Transportation said late Tuesday morning.
There remains 1″ to 2″ of water on a section of the highway for several hundred feet, the agency said, and motorists are advised to reduce speeds and use caution when entering the water.
There are cones and signs in place to assist.
The highway had been closed between Hardin and the Wyoming state line due to heavy flooding.
