The single-span, closed-spandrel arch Frankford Avenue Bridge is an early example of a concrete bridge with supporting members. The bridge's exterior is made to appear like stonework, with scoring on the spandrel walls and delineation of voussiors around the arch ring. The bridge parapet features decorative urn-shaped balusters, a design feature that became common for concrete bridges in parks and cities in the early part of the 20th century. - AsNotedIn
