Guernsey roadworks
About Roadworks
A clearer view of Guernsey’s roadworks, closures and diversions, with route planning to dodge the disruption.
The official States website is reliable, but it does not always present closures in a way that is quick to scan or route plan against. Roadworks makes it easy to draw a route to your destination and see how closures affect the journey.
How it works
The States of Guernsey publish roadworks and traffic management data via their public systems. Roadworks securely fetches that data, normalises it, and stores it in its own database.
Roadworks reads from this database rather than querying the States systems directly.
You draw a route, save it, and then you get a unique ID that you can use to reopen the same route later.
No account or user information beyond your route, should you save it, is stored.
Data updates
- Data is regularly fetched from the States of Guernsey.
- New closures, extensions, and completed works are reflected automatically.
- The map updates as soon as the database is refreshed; the time of the last refresh is shown in the map tools.
Live buses
Tick Show buses on the map in the map tools to see where every Stagecoach Guernsey bus is right now. The positions come from bustimes.org, a volunteer run site that tracks buses across the British Isles, and are refreshed about once a minute. Roadworks asks bustimes.org for the fleet no more than twice a minute however many people are looking.
A bus that has moved less than 75 metres in five minutes turns amber. That usually means it is held up in traffic, often by one of the closures on the map, though a bus waiting at the Town Terminus looks the same. Every position is kept, so over time the record shows where and when buses get stuck.
