Englands economic heartland in numbers
Mega-development across central England
More than £700m is reported to have been earmarked for spending on roads to provide infrastructure for a mega-development across central England.
Up to 1m new homes could be built along the Oxford, Milton Keynes, Northampton and Cambridge arc by 2050 under government proposals. Regional body England's Economic Heartland has recommended investment in roads from Swindon to Cambridge. 
Opponents say the homes plan will ruin green space the size of Birmingham and views are being sought by England's Economic Heartland from people and organisations across the region.
The schemes – which include junction improvements, capacity upgrades and new relief roads - would reduce congestion and improve journey times, helping to realise the region's immense economic potential, which Government has made a national priority.
