CHEYENNE, Wyo. — Usually with high wind warnings in southeastern Wyoming, it’s a matter of when — not if — parts of the highways outside of Cheyenne will close to certain vehicles.

And once again this winter during a high wind warning in the area, certain vehicles will have to make travel adjustments.

The Wyoming Department of Transportation (WYDOT) has closed a portion of Interstate 80 on Thursday morning from Exit 290 (Quealy Dome) near Laramie to Exit 235 near Elk Mountain to light, high-profile vehicles due to gusting winds and an extreme blowover risk.

Several hours after the selected closure of I-80, WYDOT made the call to also close I-25 from Cheyenne to Wheatland to light, high-profile vehicles due to the gusting winds. The full reopening time of each interstate is unknown.


Strong winds are currently pelting parts of southeastern Wyoming as an area including central Laramie County (plus most of the route between Cheyenne and Laramie) is currently under a high wind warning per the National Weather Service (NWS) in Cheyenne until 5 a.m. Friday. West winds in Cheyenne of 30 to 40 mph with 65 mph gusts are expected.

South winds of 37 mph with 57 mph gusts were recorded at 9:06 a.m. Thursday at Cooper Cove near Laramie, per WYDOT sensors. Arlington at the same time recorded 51 mph winds with 62 mph gusts.
