I contacted Mick Hepworth in the Highways department (who replied very promptly - he is fantastic, isn't he?) and he said the work hasn't been suspended. There haven't been any problems with the modelling of the road and Berkeley Homes haven't made any late changes to their development. There are problems with the diversion of the underground services which may hinder work slightly but they are continuing: work to remove the old road surface will start tomorrow.
