UK Highway Authority Road Closures
Live road closure data for the UK's national and devolved highway authorities — Transport for London, National Highways, Transport Scotland, Transport for Wales, and Infrastructure NI. These bodies manage motorways, trunk roads, and strategic A-roads.
What are Highway Authorities?
Highway authorities are the organisations legally responsible for managing the UK's strategic road network. National Highways manages all motorways and major A-roads in England. Transport for London manages the TLRN — the 580 km network of key London roads. Scotland, Wales, and Northern Ireland have their own devolved bodies managing trunk roads and motorways.
For local road closures managed by county councils and metropolitan councils, see the Councils section.

What is the difference between a highway authority and a council?
Highway authorities are organisations legally responsible for managing roads. National and devolved bodies manage strategic roads (motorways, trunk roads). County councils and metropolitan councils manage local roads. Some councils are both a highway authority and a local government body.
