“Motorists must get used to driving at 40mph on the motorway, the civil servant in charge of Britain’s roads has said as he admitted the roads will get ‘slower and slower’.  Labour said the admission was evidence that a decision to cut infrastructure spending in the early years of the Coalition meant that officials now had to manage congestion rather than invest in new roads.  The Agency is in charge of maintaining 4,300 miles of England’s motorways and A roads. Four million vehicles use the roads daily.  Mr Dalton blamed Treasury spending rules for meaning that he lost £20million from his roads spending budget due to the very wet weather in January and February.”
