This is the first time I'm joining in on this meme for "Sunday Bridges" sponsored by Louis La Vache at San Franciso Bay Daily Photo.
We came across this bridge while touring Custer State Park in South Dakota. This is called a pigtail bridge due to the way it is constructed.
Click on the photo to enlarge it so that you may be able to better read the sign about the bridge.
