What is the Strategic Road Network (SRN)?
The SRN in England is around 4,300 miles long and is made up of motorways and trunk roads, the most significant ‘A’ roads. All other roads in England are managed by local and regional authorities. The Highways England network represents around two per cent of all roads in England by length, but it carries a third of all traffic by mileage. Two thirds of all heavy goods vehicle mileage in England is undertaken on the SRN.
