SIOUX FALLS — A 73-year-old man was killed Wednesday afternoon in a single-vehicle crash near downtown Sioux Falls after failing to negotiate a curve, police said.

At approximately 2:30 p.m., police in Sioux Falls were called to the intersection of 18th Street and River Boulevard in central Sioux Falls for a priority one crash, the most severe response code.

According to Sam Clemens, public information officer for the Sioux Falls Police Department, a 73-year-old Sioux Falls man was driving westbound along 18th Street, near the transition to River Boulevard, when he failed to negotiate a curve and drove over the median, through a fence and into a tree on the south side of the road.

Life-saving measures were provided by both witnesses and first responders, but the man was eventually declared dead at the scene of the crash. Clemens said police are working to determine whether speed was a factor in the crash, adding that an autopsy will determine if drugs or alcohol were involved.

The name of the individual who died has not been released pending notification of family members.


The crash resulted in authorities closing down parts of 18th Street and River Boulevard for a short period of time, as emergency crews worked to clear up the scene. No major impacts to traffic were reported.

The Sioux Falls Police Department continues to investigate the crash.
