Some stats
Made up of: 450,000 tonnes of steel and 2.3 million cubic metres of concrete, supported by 5,200 columns
Good news is that they are building a bigger 30 mile bridge which is to be finished in 2016 (should need even more steel....I wonder where they will get the steel from) & their steel needs fall nicely into the Sundance time lines for production.
