WYDOT Data Interpretation

Please be aware of the following:  

 ●     WYDOT uses section-based reporting to indicate road conditions and road closures. The  data shown indicates the worst-case closure scenario. If any section along a given route  is closed, the entire route is treated as "closed".
 ●     Closure data is shown as the percentage of hours the designated route is closed in a  month. The number of hours varies based on the number of days in each month.
 ●     Commercial vehicle closure data includes closures to light, high-profile vehicles due to  strong winds.
 ●     Closure data for passenger vehicles does not include strong-wind closures to light,  high-profile vehicles.
 ●     Data reflects full closures initiated by maintenance employees or Highway Patrol  Troopers. Single lane closures or delays due to crashes that do not close the roads will  not be reflected in the data.
 ●     "Commuter hours" include weekends.
 ●     The data does not include ramp closures or lane restrictions due to construction.

The Wyoming Department of Transportation is able to provide historical reports with road closure information tied to a specific road and range of dates. These reports indicate when a section of the road closed, the direction of the closure, how long the closure lasted, and what conditions occurred during the closure (i.e. reason for the closure).

Here is an example of a historical closure report:  Interstate 80  Feb 18 to Feb 28 of 2023.pdf
