The definitive UK-wide map of roadworks and traffic disruptions.

Single source of truth

The Causeway Map is the UK’s single source of truth for information about traffic disruptions, displaying comprehensive information about current and planned roadworks, public events and traffic management interventions such as road closures and diversion routes.

User friendly and free-to-view, Causeway is one of the most visited, most comprehensive and most widely syndicated source of roadworks and traffic disruption information in the UK. 

Use cases

  • The Map enables highway authorities to fulfil their duty to communicate authoritative up-to-date information about roadworks, events and other activities on the highway.
  • It is the national stakeholder engagement channel through which utility companies, contractors, bus operators and emergency services rely on for information about works.
  • Users can register for email alerts about upcoming roadworks affecting their area. This is particularly useful for local councillors and others with public information duties to fulfil.
