Managing our roads
The Highways Agency operates, maintains and improves the strategic road network in England on behalf of the Secretary of State for Transport. The strategic road network in England is some 4,300 miles long and is made up of motorways and trunk roads — the most significant ‘A’ roads. Other UK roads are managed by local and regional authorities. While our network represents only two per cent of all roads in England by length, it carries a third of all traffic by mileage. Significantly, two thirds of all heavy goods vehicle mileage in England is undertaken on the strategic road network, making it the economic backbone of the country.
