From CBC.ca:
Jan. 27, 1938
In a cloud of snow and ice, the great bridge that crossed the Niagara River has collapsed upon itself. Now, all that remains of the Honeymoon Bridge are tangled cable lines, crushed wooden beams and twisted metal. Under the weight of an enormous amount of ice, the bridge’s beams gave way and fell into the frozen reservoir below. In this on-the-scene report, CBC Radio captures the spectacle of the disaster as hundreds of tourists look on in shock.
