Construction Williamsburg Bridge (9 photos)
To the late 19th century to build a 2-kilometer "suspension bridge" - it was great. With the technologies of those years without cars, electric welding and powerful dredgers it was really a feat of engineering. At the time of completion it was invested $ 24.2 million. At that time it was the largest bridge hanging span (490 m). in the world. This record was broken after almost a quarter century, in 1924, when put into operation Bear Mountain Bridge (the bridge at Bear Mountain), there's longest suspension span was 7 meters long - 497 m., With a total length of the bridge more than three times less.
