Design and construction
These bridges were designed by Keller & Harrington of Chicago, Illinois and built by the Phoenix Bridge Company of Phoenixville, Pennsylvania. Each bridge uses a 629-short-ton (571 t) over-head concrete counterweight. Originally, there were four bridges, but only two of them remain.
