Rural Wyoming is strongly impacted by hazardous weather along its road network. Interstate 80 (I-80) is a major highway that runs west to east along the southern part of the state, which is located in the Northern Rocky Mountain area of the U.S. illustration 1. The entirety of I-80 in Wyoming is over 1,800 meters in elevation, with a maximum of 2,633 meters. This elevation and Wyoming’s continental, northerly climate lead to extreme weather along I-80 throughout the year.
