why is it called the golden gate bridge

The Golden Gate Bridge gets its name from the Golden Gate Strait, the entrance to San Francisco Bay from the Pacific Ocean, not from the bridge’s color or the California Gold Rush. The term “Golden Gate” was popularized in the mid-19th century and was first used to describe the strait by U.S. Army Captain John C. Frémont in 1846, who likened the strait to the Golden Horn of Istanbul and envisioned it as a gateway to the East. When the bridge was later constructed, it inherited the name of the strait it spans, becoming the Golden Gate Bridge.
