She says the bridge is one of the most extraordinary engineering projects of all time.

It is 27 meters wide. Two large cables pass over the top of the bridge's towers. These structures stand 227 meters above water and 152 meters above the road. Each cable holds more than 27,500 strands of wire. The Golden Gate Bridge weighed 811,500,000 kilograms when it was completed in 1937.
