The average monitored road in Wyoming carries 3,650 vehicles per day. Across its 8,810 miles of monitored roads, that adds up to 21,843,304 vehicle-miles traveled per day (≈8.0 billion per year). Freight weighs heavily here: trucks are 17.9% of traffic, against 9.3% across the US.

Quieter roads than 90% of states nationwide

Wyoming's average daily traffic volume is 48% lower than the national average - 3,650 vehicles per day against 6,986 - suggesting less traffic load per road - less drive-by exposure for retail, but easier access for deliveries. Network-wide, Wyoming accounts for about 0.3% of the national total of vehicle-miles. Wyoming carries less traffic than 90% of states nationwide.

At 34.5 minutes, the average travel time matches the national level closely. On travel time, Wyoming runs longer than 83% of states nationwide.

Congestion runs 39% lower than the national level, at a ratio of 11.5%, which means smoother traffic flow - travel times are easy to plan around for scheduled deliveries.

How to read these road counts
  • The first number is AADT, annual average daily traffic: the vehicles passing a point on an average day, both directions combined and trucks included. On a divided highway both carriageways are added together.
  • Traffic changes along a road, with more near interchanges and towns and less in open country. Every figure for a road describes its busiest stretch in the county, so the two rankings show the same numbers for the same road.
  • The second number is the trucks on that stretch, a part of its AADT. The bar splits the AADT into cars and light vehicles (blue) and trucks (amber).
  • See segment-level AADT for any road on TrafficZoom.
