Georgetown bridge.—We are advised in connection with the reported reconstruction of a bridge carrying the highway over the railway tracks near Georgetown, Ont., that it will be a steel and concrete structure carrying a 20 ft. highway, on a 6% approach grade, at an elevation 23.3 ft. above the railway tracks. It is 20 ft. long, consisting of three 40 ft. spans, carried on 2 steel bents on concrete dwarfs piers with buried concrete abutments at each end. The superstructure will consist of through plate girders with I-beam stringers and steel I-beam bents with sway bracing. The floor will be of concrete slab 9 in. thick, reinforced with steel nails at 9 in. centers running longitudinally. The railway will supply the materials for the concrete substructure and will make the excavations and erect the bridge complete with their own forces. The main girders, bents and reinforcing will be supplied from the railway's own stock, and the steel I stringers will be bought locally. The work is expected to be completed about the middle of September.
