Honeymoon Bridge Collapsed
1938
The Honeymoon Bridge in Niagara Falls, Ontario, Canada was one of the world's largest arch-bridge spans. But its life ended
abruptly in the winter
of 1938,
when a rush of
water clogged with ice flooded the Niagara River, severely damaging the
bridge's supports and causing it to plummet into the gorge. (Sensing
collapse was imminent, officials had closed the bridge, so there were no
casualties.) The bridge's successor, optimistically named the Rainbow
Bridge, features elevated supports that keep the span's lowest point a
full 50 feet above the water level, 28 feet higher than the Honeymoon's
lowest part.
