RAPID CITY, S.D. (AP) — Authorities in western South Dakota have released a list of several crash-prone areas that motorists travel on in Pennington County during the Sturgis Motorcycle Rally.

The Pennington County Sheriff's Office released the data Wednesday ahead of the weeklong event's Monday kickoff.

The sheriff's office says extra patrols are already in place as a reminder for drivers to slow down on many of the curvy roadways.

The areas identified by the sheriff's office include Old Hill City Road, the junction of Deadwood Avenue North and Calamity Avenue curve, and the intersection of Highways 385 and 44 East, where most fatalities have occurred in the past three years.

Authorities say 163 accidents and five fatalities have been logged outside of Rapid City limits during the past three rally weeks.
