South Dakota Highway Patrol, Dell Rapids Police and Sioux Falls Police had to do some late night cattle wrangling after a semi tipped over on I-29 shutting down the road for most of the morning. It happened around 12:30a.m. Tuesday morning at mile marker 100 which is just right before the Dell Rapids exit on the south bound lane of I-29. The semi tipped over and the top part of the trailer was ripped open releasing about 15 head of cattle onto the road. Officers had a hard time rounding them all up but managed to get most of them into a small herd. They moved them about 2 miles away from the road and into trailers borrowed from the Humane Society. Some of the cows were trapped inside the trailer. Crews were working to free the trapped animals, using a saw and bolt cutters, but 3 of them did die. No word yet on what caused the trailer to tip over in the first place, but the driver was taken to the hospital with minor injuries.
