The bridge opened on November 1, 1957, [10] connecting two peninsulas linked for decades by ferries. At the time, the bridge was formally dedicated as the "world's longest suspension bridge between anchorages", allowing a superlative comparison to the Golden Gate Bridge, which has a longer center span between towers, and the San Francisco–Oakland Bay Bridge, which has an anchorage in the middle.
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

The clearance below required under bridges for the largest ships—container ships, ocean liners and cruise ships—is around 220 feet (67 m) so there are often bridges with approximately that height located in coastal cities with bays or inlets, such as New York City's Verrazzano-Narrows Bridge and San Francisco's Golden Gate Bridge.

By the mid-1930s Steinman had a professional reputation as one of the pre-eminent bridge engineers of the US, especially for long span suspension bridges, but his bridges were eclipsed in the public eye by his old rival Ammann's George Washington Bridge (1931) and by Joseph Strauss's Golden Gate Bridge (1937) among others. His plans for a NYC ...
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean in California, United States. The structure links San Francisco —the northern tip of the San Francisco Peninsula —to Marin County , carrying both U.S. Route 101 and California State ...
