This report describes the use of scratch gages for obtaining strain histories of bridge members. Basic components of the gage are designated and its operation is described in general terms. Stress histories, deduced from strain records, for various members of three bridges obtained through use of the gages are presented. A procedure for use in replicating sections of deteriorated members is described.
