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.

No. Motorway works are managed by National Highways using a separate system and don't appear in Street Manager, so they're not visible here. The good news is that motorway closures tend to be well publicised in advance. The works that catch people out are the ones on local roads — which is exactly what we focus on.

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. We refresh every 15 minutes and don't modify or delay the data.
