In 1974 the Research Council initiated a statewide survey of metal truss bridges to identify any with historic significance. This pioneering effort was financed with state research funds as it was intended to aid the Virginia Department of Highways and Transportation in meeting its obligations mandated by various requirements of the environmental review process. Survey reports for the Staunton, Culpeper, Richmond and Fredericksburg construction districts have been published. As the work in Virginia proceeded, interest in historic significance of bridges developed nationwide and warranted funding of the research under Highway Planning and Research funds administered by the Federal Highway Administration. A working plan was approved to develop criteria for the preservation or adaptive use of bridges and this work included surveys of metal truss bridges in the Lynchburg and Bristol districts and a statewide survey of concrete and masonry bridges. The surveys of metal truss bridges for the remaining two districts, Salem and Suffolk, were funded with state research funds. An interim report entitled "Criteria For Preservation and Adaptive Use of Historic Highway Structures a Trial Rating System for Truss Bridges" was issued in January 1978. This present report presents the results of the survey of the metal trusses in the Lynchburg district. The issuance of this report and those for the remaining three districts has been delayed because of the resignation of the research analyst originally assigned to the project. The survey results were available and were considered in the development of the trial rating system.
