Best Practices for the Rehabilitation and Moving of Historic Metal Truss Bridges

The Virginia Department of Transportation (DOT) is responsible for the management of about 30 historic truss bridges. Too often, these structures do not meet today’s traffic demands or safety standards. Their general deterioration necessitates that they be disassembled and relocated, rehabilitated and re-erected, or stored. The technology and materials used to build them are no longer in use, and many people with practical experience are no longer working. Little information is readily available on effectively identifying and safely performing necessary operations. Virginia DOT’s Knowledge Management Division and the Virginia Transportation Research Council interviewed active and retired engineers, consultants, field personnel, environmental specialists, and architectural historians to collect best practices related to pin-connected and riveted truss bridges. Discussion of the issues faced by those moving and rehabilitating historic metal truss bridges is framed by using the process followed for the recent rehabilitation of a historic truss bridge in Goshen, Virginia. Best practices identified through the examination of this and other projects are also presented.
