Seven Wonders of the Modern World

By Matt Rosenberg, About.com Guide

The Golden Gate Bridge, connecting the city of San Francisco with Marin County to its north, was the bridge with longest span in the world from the time it was completed in 1937 until the completion of the Verrazano Narrows Bridge in New York in 1964. The Golden Gate Bridge is 1.7 miles long and about 41 million trips are made across the bridge each year. Prior to the construction of the Golden Gate Bridge, the only mode of transportation across San Francisco Bay was ferry.
