Georgetown highway bridge.—The bridge construction forces are rebuilding the highway bridge at mile 28.47, Brampton Subdivision, at Georgetown, Ont. The present structures, which is of timber, construction, consisting of frame bents supporting longitudinal stringers, with a 3 in. plank floor, was built about 18 years ago, and is being replaced on account of its physical condition. The new structure will consist of concrete abutments and dwarf piers, and the superstructure will consist of a deck plate girder span of 32 ft. over the main line, with a deck plate girder span of 25 ft. on the north side and a similar span of 28 ft. on the south side. The span over the main line will be carried on steel columns, resting on the dwarf concrete piers. The steel spans will be supplied from stock spans released from other places, and readjusted to suit this bridge. The floor system will consist of 24 in. rolled beams spaced approximately 14 ft. centers and rivetted to the side girders, on which will be placed released T girders embedded in concrete to form the flooring. The bridge will have a clear width horizontally of 20 ft. and a vertical clearance of 22 1/2 ft. over tacks. The present approach gradient of 11.43% on the north approach, will be reduced to 8.13%, and that on the south side will be reduced from 10% to 5%. The bridge is being rebuilt according to the Canadian Engineering Standards Association recommended practice for steel highway bridges, 1922, and will be capable of carrying 15-ton trucks.
