Tall and Strong
Tallest Bridge Towers
The Golden Gate Bridge not only set the record for longest bridge span when completed in 1937, it also had the tallest towers.
Honeycomb Legs – Strong But Light
This innovation introduced by the Golden Gate Bridge provided the strength to withstand the tremendous weight transferred to the tops of the towers by the cables, and also to resist horizontal loads due to wind and earthquakes.
Over a Million Rivets
Each tower has over a million rivets. A red-hot rivet with a round head on one end was inserted through holes to join pieces of steel. Then while the round-headed end was held securely, a riveter with a power tool hammered ("bucked") the plain end into another mushroom-shaped head, clamping the pieces together. |
