CASPER, Wyo. — Wyoming travelers are waking up to miles of closed roads early Thursday after a winter storm moved through the area on Wednesday.

As of 5 a.m. Thursday morning, Interstate 80 is closed either partially or completely from Cheyenne to the Utah border, and Interstate 25 is closed from Cheyenne to Glendo, according to the Wyoming Department of Transportation.

Major portions of US 30 and US 87 are also closed. US 287 is closed from Laramie to Medicine Bow.

The Laramie County School District #1 announced early Thursday that school will be closed due to dangerous travel conditions.
