Last month while visiting Harrisburg, Pennsylvania I discovered this bridge and was drawn to it immediately. The Walnut Street Bridge is a wrought iron built by the Phoenix Bridge Company and opened it 1890. The bridge was damaged in 1972 Hurricane Agnes flood and was subsequently closed to motor vehicles and converted to a pedestrian and bikeway.
North American blizzard of 1996 caused rising flood waters and a large ice floe lifted two of its seven western spans off their foundations and swept them down the river.
The Walnut Street Bridge is one of the longest pedestrian bridges in the world and was listed on the National Register of Historic Places in 1972. It is also recognized as a Historic Civil Engineering Landmark.
