Police presence is reported on a major UK motorway causing closures. The M1 in Derbyshire was initially shut down in both directions earlier today due to a law enforcement incident at J29, but all lanes have since reopened, though delays are expected as traffic normalizes. In a separate event, the M1 southbound between J21a and J21 in Leicestershire is closed due to a multi-vehicle collision, resulting in significant congestion.
Motorists traveling south on the M1 are advised of 50-minute delays between junctions J22 and J21, with Traffic England projecting delays until around 1:15 pm. National Highways confirms two lanes closed southbound between J21a (A46) and J21 (Leicester) due to the collision, with emergency services on-site and a 40-minute delay along with four miles of congestion.
National Highways reports full reopening of the M1 but warns of ongoing delays as traffic flow returns to normal. Motorists are encouraged to reroute or delay their journeys as a section of the M1 remains closed. Additionally, a diversion is in place with a hollow triangle symbol for affected drivers.
For further information, National Highways advises checking their website, travel apps, or contacting their 24/7 contact center. The closure on the M1 northbound between turn-offs for Chesterfield and Barlborough is due to a police-led incident, with ongoing work by Derbyshire Police and traffic officers for traffic management.
