US20/WY789 remains closed this morning between Shoshoni and Thermopolis.

Wyoming Department Of Transportation crews from Shoshoni and Thermopolis have worked all night to break up the rock which is blocking a lane of the highway just east of the Boysen State Park headquarters.

The rock fell on the highway between 8 p.m. and 9 p.m. last night.

There is no estimated time of when the highway will reopen. Check wyoroad.info for road conditions.
