Posted by Stephen Bauman on Tue Nov 3 00:08:37 2009, in response to Strengthening Queensborough and Brooklyn Bridges, posted by rashidas on Mon Nov 2 21:03:19 2009. Can the Queensborough and Brooklyn Bridges be strengthened enough to carry the weight of an AirTrain?AirTrain cars are approximately the same weight of current 60 footers. These are much heavier than the wooden El cars that once ran on both these bridges. The 1950's Brooklyn Bridge reconstruction removed the middle trusses. Their removal reduced the bridge's live load capability. So, the Brooklyn Bridge can no longer handle the lighter El cars it once carried. The Queensboro's 1980's architectural striptease removed two full time automobile lanes and a pedestrian lane. The purpose was to prevent a catastrophic failure by reducing its total load (live and dead). Increasing the live load with the likes of AirTrain is not an option. |
