HELENA — Montana authorities have reopened an interstate highway that was temporarily closed in both directions after high water washed out a culvert running underneath it and caused the roadway to crumble.
The Jefferson County Sheriff’s Office says Interstate 15 between Jefferson City and Boulder was shut down on Friday, and reopened late Sunday.
Western and central Montana streams and rivers are running high due to the rapidly melting mountain snowpack and recent rainfall in the area.
Flooding is ongoing in some western Montana waterways, including the Clark Fork and Bitterroot rivers.
The Helena Independent Record reports that travelers should expect single-lane traffic for about 2 miles (3 kilometers) south of Jefferson City.
