Construction of the bridge started in 1933. Engineer Joseph Strauss and architect Irving Morrow created an extraordinarily beautiful bridge in an extraordinarily beautiful setting. The designs for the Golden Gate Bridge showed the greatest attention to artistic detail, especially on the two streamlined modern towers. The bridge’s 4,200 feet of clear span (from tower to tower) was the longest in the world until 1959. On April 19, 1937, the bridge was completed and the official dedication took place on May 27.
