Common questions

This page shows every active roadwork inside the area — closures, lane restrictions, two-way lights, give-and-take systems and works without traffic management. The road closures page is the same data narrowed down to full closures and lane closures only.

Some works are submitted by multiple promoters (the council and a utility, for example) or are split across more than one permit. We try to group these where the references match, but if you spot duplicates please send us a note and we'll tighten the dedupe.

Only works promoters are legally required to notify on Street Manager appear here. Emergency closures for flooding, local events or short-notice council decisions go through a different process — your local council's website or social channels is usually the quickest source for those.

Local roads come from the UK Department for Transport's Street Manager service. Motorways and trunk roads come from National Highways. This page is rebuilt four times a day so counts and listings stay fresh, and we don't modify or filter what promoters submit.
