but I'd like to see the first sod turned soon
and that should only happen once all roads are constructed or existing roads widened, new rail lines are completed - both to within 200m of site (so small portions can be finished when airport site is near ready) and then those roads and railway actually mean something i.e. join up with existing 3 or 4 lane roads and a rail line directly to city centre via existing airport. Then the first sod can be turned on the single runway airport.
