UPDATE (3:30 p.m.)

Jeff Goetz, WYDOT spokesperson, provided these additional details regarding the crash: 

"Update on snow plow crash: No injuries to the plow driver nor to the drivers of the two semis. There was no diesel fuel spill as initially reported - what spilled was the brine mixture used to help melt ice that spilled along with a good amount of sand from the snow plow."

==============================================================

Wyoming Highway 220 was closed west of Independence Rock on Thursday after a WYDOT snowplow overturned and another crash resulted.

Jeff Goetz, a spokesperson for WYDOT, said in a statement that the plow overturned at roughly 1 p.m. and ended up on its side in the middle of the highway. Afterward, one semi truck rear-ended another which was trying to stop for the crash.

The highway was closed in both directions between Alcova and Muddy Gap with no estimated reopening time as of 2:15 p.m.

Goetz said there were indications that some diesel fuel spilled as a result of the commercial trucks colliding, and a hazardous materials crew has been dispatched.

Goetz did not have information as to whether anyone was injured or any other vehicles were involved.
