Interstate 90 reopened two lanes after flooding closed all four lanes for several hours Thursday morning near Crow Agency due to rising floodwaters from the Little Bighorn River.

Only the driving lanes are open, and the speed limit is restricted to 35 mph from Crow Agency to Garryowen, according to the Montana Department of Transportation.

"Water continues to be an issue in the area but has receded enought to allow one lane (driving lane) open," according to the Montana road report. "Reduce your speed and expect one lane traffic."

While the interstate was closed, eastbound traffic was being re-routed at the Little Bighorn interchange, mile marker 510.9, and onto the westbound lane of the Frontage Road, where eastbound traffic was also blocked by water.


Interstate 90 is closed as water covers all lanes.

Westbound traffic on I-90 was likewise being re-routed eastbound on Frontage, at interstate mile marker 514.9 near Garryowen.
