why is it called golden even though it is red? is it because it is so tall it can "reach the Heavens"?

The Bridge is actually named for the Golden Gate Strait, the narrow entrance between the Pacific Ocean and the San Francisco Bay. The strait was named by explorer and U.S. Army officer John C. Frémont, who marveled at its beauty in 1846—two years before the discovery of gold in California.

The bridge got it's name after the Golden Gate Strait, the narrow entrance between the Pacific Ocean and the SF Bay.
