More than 30 cows were running loose on an Interstate in Oregon on Sunday after a livestock trailer overturned, shutting down the highway for hours. 

The accident happened on March 13th near Tualatin, Oregon. 

According to KGW 8, the cattle hauler crashed on a bridge along Interstate 5 near the Wilsonville Road exit. The wreck sheared off the top of the trailer, freeing many of the cows inside. Several of the dairy cows even fell from the bridge and were killed on impact. A total of 31 cows were inside of the trailer at the time of the crash. 

The Oregon State Police responded to the scene and shot several of the injured cows to “put them out of their misery,” while others roamed free along the interstate, prompting round-up efforts. The freeway was shut down for three hours as officials worked to capture the cows and clear the wreckage. Several motorists stuck in the traffic captured video of the incident. 

The last cow was finally rounded up and loaded onto a new trailer by 5 p.m. after traffic had already been at a standstill for three hours. The truck driver in the incident was unharmed and did not require medical attention. 

It is not clear what citations, if any, were issued as a result of the incident. The exact reason behind the crash has not been released.
