Bridge Documentation

This pair of bridges offer unusual construction details as they serve their purpose of providing an approach to the Rankin Bridge entrance. The two bridges are positioned at 90 degrees and meet at a shared abutment which also supports an intersection. Of note is the continuous girder design of the Talbot Avenue bridge and the Kenmawr Avenue Ramp Bridge is noted for its riveted steel hammerhead piers, a design usually only used in concrete. Above, the total length is the added length of both bridges, and the Kenmawr Avenue spans are listed as approach spans.

The bridge carries 4 lanes of traffic and 1 sidewalk of a ramp to the Rankin Bridge (02745600002347) over a street and single abandoned track of the Union Railroad, US Steel's inter-plant rail carrier. The Union RR (est. 1894-1907) has each been determined eligible by the SHPO, but the bridge is not related to its function or historical development.
