Road Closures in Hemel Hempstead

A few things can cause this. The promoter (the council or utility company) may have submitted incomplete or late data to Street Manager. It could be an emergency that appeared with very little notice. Or it might be something on our end that needs a tweak. If you spot a gap, drop us an email or use the chat — tell us the road and we'll look into it.

Roadworks Radar builds its picture from event notifications sent through Street Manager. If a closure was already in place before we started receiving data, we may have missed the original notification entirely. Very long-standing closures — ones that have been there for many months — might not appear as a result. It's a known gap that should close as our dataset matures. For closures that have been around a long time, your local council's website is the most reliable check.

Yes. We now include motorway and trunk road closures from National Highways alongside local road data from the Department for Transport. Look for the blue NH badge on motorway works. Together, these sources give you a comprehensive view of roadworks across England's entire road network.

These won't appear here. Street Manager only covers works that promoters are legally required to notify. Emergency closures caused by flooding, local events, or short-notice council decisions go through a different process. For that kind of disruption, your local council's website or their social media channels are usually the quickest source.

Directly from the UK Department for Transport's Street Manager — the official system that councils and utility companies must use when notifying about works on public roads. This page is rebuilt four times a day so the data is never more than a few hours old, and we don't modify or filter what promoters submit.
