This bridge is a very unusual structure, not only because of its structural design, but also because bridges built in the late 1960s did not normally place as high a priority on aesthetics as this bridge did. The bridge was designed to deal with a large freeway that cut Point State Park off from downtown Pittsburgh, and to do so in a way that people would see a gateway to the park rather than an unsightly freeway. With a very shallow arch for a span of its length, the structure presents a pleasing but most unusual appearance. The design is equally unusual since it features a three hinge design as well as post-tensioning. The bridge is a ribbed arch bridge, but the ribs are covered with a curving shell for aesthetic purposes. George S. Richardson of Richardson, Gordon, and Associates was the engineer for the bridge.
