Swing Bridge at Sabula

A massive truss bridge with steel spans located in 42N country (42.06N, 90.16W) at Sabula, Iowa on the Mississippi River carries one track for the Canadian Pacific Railway.

The Iowa side span pivots 90 degrees to disconnect the rail line. By doing so the swing bridge allows tall ship traffic to pass without incident. A close look at the photos above reveal that the utility lines are always connected. Know that.
