THE LIZOTTE BRIDGE A REVIEW AND DISCUSSION OF THE CASE FOR GALVANIZED BRIDGES, BY J. R. HALL

THE FIRST HOT-DIP GALVANIZED CONVENTIONAL STEEL BRIDGE, THE LIZOTTE BRIDGE, WAS RECENTLY OPENED TO TRAFFIC NEAR QUEBEC CITY, CANADA. PROBLEMS INVESTIGATED BY THE QUEBEC DEPARTMENT OF PUBLIC WORKS INCLUDED PLANT AND KETTLE CAPACITY OF LOCAL GALVANIZERS, POSSIBILITY OF WARPAGE, ACID ENTRAPMENT, PHYSICAL EFFECTS OF PICKLING AND GALVANIZING, AND SLIP RESISTANCE OF GALVANIZED CONNECTIONS. USE OF HIGH-TENSILE BOLTS, DESIGNED TO DEVELOP FULL FRICTION AT THE CONTACT SURFACES, IS RECOMMENDED. NO EFFECTS ON PHYSICAL PROPERTIES RESULTED FROM GALVANIZING. THE ADDED COST WAS ABOUT 3 PERCENT OF THE COST OF THE ENTIRE PROJECT. IF A PAINTING PROGRAM IS INSTITUTED BEFORE THE FIRST RUST, THE BRIDGE WILL REMAIN NEW STRUCTURALLY AND ESTHETICALLY, AND WILL COST TAXPAYERS LESS THAN ANY OTHER COMBINATION OF MATERIALS OR COATINGS. CONSIDERING THE NUMEROUS ADVANTAGES OF STEEL AS A STRUCTURAL MATERIAL, THE USE OF GALVANIZED STEEL FOR SMALL BRIDGES AND HIGHWAY STRUCTURES OFFERS ADVANTAGES UNCHALLENGED BY OTHER MATERIALS.
