The Wyoming Department of Transportation announced this morning that a Landslide on US 14, east of Sheridan at Jim Creek Hill, has prompted WYDOT maintenance personnel to re-route traffic around the slide area.

WYDOT personnel first noticed the slide earlier this spring and had been monitoring it and were in the process of investigating the slide area and determining what the best options for potential repair would be. WYDOT geotechnical engineers have also been on site to assess the slide area. However, last week the slide moved significantly and WYDOT took emergency action to re-route traffic away from the slide.

WYDOT maintenance crews were able to move the roadway into the hillside and pave a bypass area for traffic. WYDOT Maintenance crews also installed barrier walls as a safety precaution. Traffic in this area has been narrowed and the speed limit has been reduced to 30 mph for safe travel through the detour area. Motorists are advised to use caution when traveling through this area.

The term ‘landslide” describes a variety of processes that result in downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of theses. This particular slide is an Embankment Slide which occurs under the road way. Another type of landslide common to this area is a Backslope Failure slide which is when debris drops or slides onto the roadway from above.

A good example of a Backslope Failure slide is what WYDOT calls the TIFF slide also on US 14 at mile post 13 just a few miles prior to the Jim Creek Slide area. The Tiff slide is scheduled for repairs this spring/summer. This slide has encroached onto the edge of the roadway and caution is advised for travel in this area.
