Caption: The Humber River CN Railway Bridge crosses th e mouth of the Humber River, south of The Queensway and north of Lake Shore Boulevard and the Gardiner Expressway. Constructed in 1911 for the Grand Trunk Railway, this four-track ra ilway bridge consists of steel plate girders spanning a concrete substructure. Two spans are carried by a central stone pier and abutments, which incorporate portions of the nineteenth century stone a butments that supported the Great Western Railway bridge that previously occupied the site. The property holds physical value as a unique integration of 19th a nd early-20th century bridge construction methods and materials. Subs equent modifications to enable the bridge’s ongoing use have not significantly de tracted from its integrity and legibility as an amalgam of construction techniques from two distinct periods. The old span is moved on to the waiting flatcar. It will be secured for movement to Mimico. The Western Bridge Co. Designed and built this span crane specifically for this job. It was assembled on site the night before the first span was removed.
