The VN Bridge can support rail car weights and more.The VZ live load is 4800 lb/foot. The Williamsburg is 7900 lb/foot and the Manhattan is 10,000 lb/foot. The way Ammann's bridges came in at significantly lower cost was reduced live load capacity. The VN Bridge can support rail car weights and more. It cannot even support gridlock with fully loaded trucks. Another of Ammann's tricks was to trust in the probability that the worst case scenario would never happen. |
