We've come a long way in bridgebuilding since crossing a river
on afallen log. The first bridges were built with wooden planks,
ropes and stones, which gave way to iron, then to steelones. Bridge
building techniques alsoevolved each with advantages thatmade it
the right choice for a particularlocation.

iconic

todesign a bridge that at the time would be the
longest suspension bridge in the world, withtowers being the
tallest structures in the Western Hemisphere: the Brooklyn Bridge

One interesting note about the BrooklynBridge: it stood fast
while other bridges builtaround the same time had crumbled.
Engineers credit Roebling for designing abridge and truss system
six times as strong ashe thought it needed to be!

3. TOWER BRIDGE It's funny to think about ancient traffic jams,
but that was why the Tower Bridge in
London, England was built. By the end ofthe 19th century, the
development of theeastern part of London caused such a load
on the London Bridge that the city decidedto build a new
bridge.
