The proposed replacement crossing of the Firth of Forth is set to be the largest construction project in Scotland in a generation, creating a new modern landmark structure.
Construction of the bridge is expected to start in 2011 and take 5 ½ years to complete at an estimated cost of £3.2 - £4.2 billion (in 2016 prices including VAT).
