 State media said a sudden downpour and flash floods had caused the collapse in Shanxi province. Photographs show one section of the highway dangling into the river below. The 11 dead were found in five cars that were pulled from the water. Rescuers are searching for 20 more vehicles that fell off the bridge. On Friday, at least five people were killed in flooding and mudslides in another part of the province. There's been heavy rain and flooding in other parts of China too.
