English: The Manchester Bridge replaced the old wooden Union Bridge, the first bridge erected at the Point and demolished in 1907. Both bridges spanned the Allegheny, connecting the Point of Pittsburgh to its North Side. The super-structure consisted of two Pennsylvania through-truss spans, each 531 feet long, with a clearance of 70 feet above harbor pool level. The designs of the bridge and the finely crafted, ornamental ironwork of the portals were executed under the direction of the Pittsburgh Department of Public Works.
