A transporter lost animal carcasses on the Autobahn 14 from Halle to Magdeburg on Wednesday at the level of the Calbe exit.
The road in the direction of Magdeburg had to be closed, as a police spokeswoman said.
Local drivers were asked to drive around the area extensively.
The road maintenance department was used to clean the road.
