Roads we manage
We manage the strategic road network (SRN) in England, comprising motorways and some A roads. Our road network is essential to the growth, wellbeing and balance of the nation’s economy.
The strategic road network (SRN) is arguably the biggest and most important piece of infrastructure in the country. Its 4,500 miles of motorways and major A roads are at the core of our national transport system.
Its many arteries connect our major towns and cities, ensure commuters make it to work every day, and help millions of us visit our friends and families.
The SRN is the most heavily used part of the national road network, carrying a third of all traffic and two-thirds of all freight. It provides businesses with the means to get products and services to their customers, gives access to labour markets and suppliers and encourages trade and new investment.
