It is named the Golden Gate because it is the entrance to the San Francisco Bay from the Pacific Ocean. The Golden Gate Bridge the total length of the bridge is 1.7 miles (8,981 ft or 2,737 m).

The length of the suspension spans, including main span and side spans, is 1.2 miles (6,450 ft or 1,966 m). The two beautiful Art Deco towers are almost 820 ft or 250 meter tall, (746 feet above the water,and more than 20 meter is below the sea level). During construction, a safety net suspended under the floor of the Bridge from end to end, the net saved the lives of 19 men who became known as the “Halfway-to-Hell Club.” Only eleven workers died during construction .
