Lion causes a long traffic jam in South Africa's Kruger National Park while crossing a bridge.The video, shot in 2014, shows dozens of cars stopped as tourists observe the animal walking peacefully."We were driving through the southern portion of Kruger National Park and observing a group of hippo in the river when we saw a bunch of activity of the bridge ahead of us," the filmer wrote online."Thinking that it might be a lion that was attracting all the attention, we drove up there to investigate.""Sure enough, a young male lion was crossing the bridge and stopped all traffic in both directions. We sat there for over 30 minutes observing and photographing the lion at a safe distance," they added.
