Sturgis Motorcycle Rally to Attract 700K But Watch Out For These Speed Limit Reductions

Sturgis, SD – It’s the time of year when South Dakota officials change speed limits due to increased traffic volumes associated with the annual Sturgis Motorcycle Rally.

Sturgis 2021 kicked off Friday and will run through Sunday, August 15.


In preparation, the South Dakota Highway Patrol (SDHP) issued a reminder to motorists that the posted Interstate 90 speed limit will be reduced to 65 MPH (from 75 MPH) on Thursday, running through the end of the event.

The speed reduction on I-90 will begin west of Exit 55 (Deadwood Avenue) in Rapid City to west of Exit 30 (Lazelle Street) in Sturgis.

The South Dakota Department of Transportation (SDDOT) also announced two additional speed limit reduction locations:

• SD Highway 34 speed limit will be reduced from 45 MPH and 65 MPH to 35 MPH from Blanche Street in Sturgis east 3.8 miles (east of Buffalo Chip).
• SD Highway 79 speed limit will be reduced from 65 MPH to 45 MPH from the junction of SD Highway 34 north 1.75 miles (north of Iron Horse Campground) and from 0.05 mile south of the intersection with Bighorn Road north 0.8 mile (near Full Throttle Saloon and Drag Pipe Saloon approaches).

The speed limit reductions in the above locations will also be in effect through Sunday, August 15.


Officials with SDDOT said message boards and speed trailers at various locations along I-90 will display alerts regarding traffic conditions, crashes causing delays and extreme weather events during Sturgis.

In addition, temporary traffic lights will be stationed at the following locations:

• I-90 Exit 32 WB ramp
