LOAD TESTING AND EVALUATION OF TURNER'S BRIDGE. STRUCTURAL RESEARCH REPORT

Turner's bridge was evaluated in 1985 according to the Ontario Highway Bridge Design Code specifications. This evaluation resulted in recommendations for considerable rehabilitation in order to avoid severe posting restrictions. The westerly truss underwent limited reinforcing of some critical diagonal members in 1985 as a means of keeping the bridge open. Due to the high costs associated with the remaining proposed reinforcing, the County of Bruce requested that the structure be load tested by the Ontario Ministry of Transportation. The bridge was included in the Ontario Ministry of Transportation's 1986 bridge testing program. The structure is comprised of two steel through truss spans, each supporting concrete decks on steel stringers and floor beams. Both truss spans were proof tested in July 1986 and the results of these tests and the subsequent evaluation are the subject of this report. The testing confirmed the use of frame analysis as a tool for evaluating the steel trusses. The report recommends a new triple posting of 18, 32 and 36 tonnes.
