Interstate Crashes in South Dakota
Collisions on major highways such as I-90 often result in more serious outcomes due to high travel speeds and traffic volume. The January 1 crash near mile marker 78 highlights the risks drivers face along this critical east–west route through Rapid City and beyond.
Accidents on interstate highways often involve chain reactions or limited reaction time for drivers traveling at 70+ mph. When weather, fatigue, or sudden merging are added to the mix, even a momentary lapse in focus can lead to life-altering consequences.
