Posted by randyo on Sat Jul 25 13:40:33 2009, in response to Re: The Manhattan Bridge, posted by Chris R16/R2730 on Sat Jul 25 11:53:49 2009. Most bridges are designed to flex but the flexion is unnoticeable unless it observed in a time lapse photo sequence. The problem with the Manny B is that the tracks should have been put in the middle like the Willy B or the Bkln Br and the problem wouldn't have been so severe. When the bridge was designed, the then bridge commissioner (I don't recall his name at the moment) commented that the bridge could not support the weight of the trains it was designed to carry and he was immediately fired. The principal reason that the Manny B suffered from the type of stress that it did was due to the majority of BMT bridge service Sea Beach West End and Brighton) for many years using the present A/B tracks while the H tracks saw mostly rush hour Culver and banker special service service. The Chrystie merger of 1967 corrected that problem to a small degree but the twisting of the bridge from many years of mostly one sided operation ultimately resulted in the bridge having to be shut down the way it was to repair the conditions. |
