Everyone likes the Brooklyn Bridge and I’ve walked over it many times but it hit me that I’ve never really explored any of the other bridges on foot. You don’t get the same unobstructed views of the skyline that you do from the Brooklyn Bridge but there is something cool about the massive steel structure around you. And yes, I did accidentally walk up the bike side. My bad. (The south side of the bridge has the pedestrian walk way and there is a connection between the bike and foot sections about half way across the bridge).
When it opened in 1903, the Williamsburg Bridge was the longest suspension bridge in the world, with a span of 1600 feet and a total length of 7308 feet and the first with all-steel towers. The 310-foot steel towers support four cables, each measuring 18_ inches in diameter and weighing 4,344 tons. In all, nearly 17,500 miles of wire are used in the cables that suspend the bridge 135 feet above the East River. The massive stiffening trusses were designed not only to withstand high winds, but also to support rail traffic on the deck.
