span of 209 feet (64 m) and a rise of 29.71 feet (9.06 m); the ribs of the other spans vary from 176.5 to 121 feet (53.8 to 36.9 m) in length, with rises from 29.2 to 19.1 feet (8.9 to 5.8 m). The three interior ribs in each span are grouped together near the center of the roadway where a streetcar line was originally located. The two outer ribs are more widely spaced and carry thin concrete fascia walls concealing an open-spandrel design. Reinforced-concrete spandrel columns carry the reinforced-concrete roadway. The viaduct spans the rail yard consists of a reinforced concrete slab deck carried by transverse bents of concrete-encased structural steel. The piers are granite-faced reinforced-concrete.

formwork and the wet concrete during construction, an initial compressive stress was developed in the steel prior to the setting of the concrete. This prestressing of the steel allowed a much higher proportion of its ultimate strength to be utilized, allowing, in turn, the use of smaller and lighter arch ribs and a less massive substructure.

The
Memorial Bridge features a seven-span, reinforced-concrete deck rib arches, with a nine-span reinforced concrete slab viaduct. Each of the river spans is made up of five Melan-type, two-hinged, reinforced-concrete arch ribs of parabolic profile. The bridge's longest ribs have a center to center
