Golden gate turns 75

San Francisco,US: An incredible firework display celebrated the 75th anniversary of the Golden Gate Bridge on Sunday - a man-made structure.

Constructed during the great depression, it was the longest suspension bridge ever built when it opened on May 27, 1937, stretching a mile across San Francisco Bay.

Over the years, the San Francisco landmark has also attracted negative attention with an estimated 1,200 people committing suicide at the bridge.

The Golden Gate Bridge Highway and Transportation District is now studying the costs and feasibility of draping nets along it to catch any jumpers. Nets were last used during its construction and saved the lives of 22 workers.
