SAN FRANCISCO (KTVU) - The most iconic landmark on the west coast celebrates its 80th birthday this weekend.
The Golden Gate Bridge opened on May 27, 1937.
The steel came from the east coast, and was shipped here by way of the Panama Canal.
It took four years to build and cost about $27 million.
The 4,200 foot long suspension span was the longest in the world until 1964.
It is now the ninth longest in the world.
