The Department of Transportation (DOT), South Dakota Highway Patrol, and Sturgis Police worked for a year on traffic plans in regards to the 75th annual Sturgis Motorcycle Rally. The Rapid City Journal reports that on Saturday, August 1st the traffic is expected to crescendo after a higher than normal usage. The groups have coordinated to help traffic flow as quickly as possible, but with estimates of over 1 million visitors, gridlock is still possible.
The DOT placed digital message boards along I90 to help warn traffic approaching Sturgis when they should be prepared to stop ahead. There are also four tiers of plans in mind that can be used to help move traffic in town if traffic is backed up too far on the exits.
