Rehabilitation of Two 1890s Metal Truss Bridges
During the period from the last decade of the 19th century through at least the early 1930s, we experienced a great number of long span metal trusses. Two of these examples are the Walnut Street Bridge, a 2370 feet long truss and viaduct structure completed in 1891 across the Tennessee River in Chattanooga, Tennessee, and the Strawberry Mansion Bridge, a 1250 feet span composed of deck trusses and a 3-span steel arch built in 1897 across the Schuylkill River in Philadelphia, PA. Both of these bridges are fine examples of the great work that was accomplished by the engineers and fabricators during the latter part of the century. They remain in service today, the Walnut Street Bridge serving as a pedestrian bridge and the Strawberry Mansion bridge carrying pedestrian and vehicular traffic. Whereas both structures fell into some sort of neglect during the late 1970s and 1980s, there existed within the community a spirit and willingness to commit the necessary resources to structurally rehabilitate these bridges and restore important elements of the existing bridge so that a good portion of the original fabric will remain for future generations to enjoy. This paper will describe the history of each bridge and the engineering analysis and details that were accomplished so that they could be returned to useful service.
