U.S. 20 Junction List
Most of the information contained herein is derived from the Wyoming Department of Transportation 1997 Wyoming Reference Marker System. That guide lists highways by their state inventory control number. Since these inventory numbers are not featured on the highways, this list is designed to provide mileposting information for individual, signed highways.
The following table lists all of the major towns, geographical features, highway junctions, and points of interests along the route. Each of the signed routes (including multiplexes) are shown in the first column for each entry. The second column shows the actual milepost marker as found on the highway; note that the mileposts rarely reset at zero at the start of new highways. In the third column is the description of the town or geographical feature. "CL" refers to "City" or "Corporate" Limits. The fourth column lists the state control inventory route, and the fifth column provides the distance between each geographical feature. If there are multiple features that require several lines to explain, then the distance in this column would be zero. Finally, the last column shows the cumulative mileage of the route. The last, bold-faced number in the column provides the total mileage for the signed route.
