text:  A highway bridge in northwestern China partially collapsed last night after heavy rain. Authorities say at least 11 people have died. NPR's John Ruich has more. The bridge gave way on Friday night at about 8.40 p.m. local time, the result of a sudden downpour and flash flooding, according to reports. It happened in a mountainous part of Shanxi province about two hours southeast of the city of Xi'an.
