Update: Bridge collapses, one worker missing

A man is missing after a railroad bridge collapsed over the Elkhorn river in Norfolk on Tuesday.

It all happened around noon.   Three railroad workers were checking on the bridge when it collapsed, dumping them into the fast-moving current.  Two were pulled out alive and the search is still on for the third.

Just after the bridge went down, emergency crews began calling for voluntary evacuations in some areas because of rising waters.
