Williamsburg Bridge connects Manhattan to Williamsburg, in Brooklyn. This bridge is not as famous as Brooklyn Bridge, but it is so cool. It is pink inside, and there is a bike path and a pedestrian path. And it is usually not that crowded. When it opened in 1903, the Williamsburg Bridge was the longest suspension bridge in the world, carrying rail, trolley, carriages and pedestrians. The Williamsburg Bridge was one of the last major bridges designed for the horse and carriage. By the 1920s, when the automobile became a major mode of transportation, the trolley tracks were replaced with roadways.
