ℹ About UK Bypasses
UK bypasses are sections of A-road or motorway built to divert traffic around congested town centres. They range from short 3-mile routes like the Baldock Bypass to major motorway bypasses like the M5 Exeter Bypass. When a bypass is closed, traffic is diverted through the town it was designed to avoid — causing significant disruption.

Frequently Asked Questions About UK Bypasses
What is a bypass?
A bypass is a road built to divert traffic around a congested town or city centre. UK bypasses are typically A-roads or motorways that allow through-traffic to avoid town centres, reducing congestion and improving journey times.
Why are bypasses closed?
Bypasses are closed for utility works, resurfacing, bridge maintenance, and accident clearance. Because bypasses carry high traffic volumes, closures cause significant disruption as traffic is diverted through the town the bypass was designed to avoid.
How do I check if a bypass is closed?
Bypass closures are reported through the UK government's Street Manager system and National Highways. This page shows live closure data for all major UK bypasses. Select your bypass above to see current closures and planned roadworks.
What happens when a bypass is closed?
When a bypass is closed, traffic is diverted through the town centre it was designed to avoid. This can cause significant congestion in town centres, particularly for HGVs that cannot use narrow town centre roads.
