Abstract

In an attempt to preserve a representative number of fast-disappearing old metal truss bridges, a variety of methods of modifying them for contemporary use was explored. Twenty historic metal highway truss bridges located in Virginia were used as case studies. The bridges were investigated as to their potential for sympathetic strengthening and widening to meet current federal standards. In most situations the loading requirement can be met by discreet strengthening, but the geometric requirements can not be met without severe violation of the historic features of the bridges. Also explored were nonvehicular uses of these bridges for controlled architectural conversion into craft centers, museums, restaurants, housing, and the like, at either the present site or a new one. Although the bridges investigated are in Virginia, the findings should have application for those in other states.
