Rock Island Swing Bridge
Rock Island Swing Bridge was a swing bridge that spanned the Mississippi River between Inver Grove Heights and St. Paul Park. It was also known as the Newport Rail Bridge, as it had a spur to Newport and J.A.R. bridge, after previous owners Joan and Al Roman of Chicago. It was one of the few double-decker bridges on the Mississippi, with the top level formerly used for railroad traffic and the bottom level formerly used as a road crossing. -from Wikipedia
