The A1(M) northbound is completely closed between junction 6 (Welwyn, Welwyn Garden City) and junction 7 (Stevenage) after a life-changing collision involving a motorbike rider. Hertfordshire Police are at the scene handling the incident.
Partial Closure on Southbound Side Also Causes Delays
One lane of the southbound carriageway is also closed, adding to the chaos. The northbound shutdown is expected to last throughout the afternoon as emergency teams carry out collision investigations and clear the wreckage.
Complex Diversion Route to Avoid the Crash Zone
Drivers are urged to follow the official diversion:
- Exit the motorway at junction 6.
- Follow signs marked with a black circle.
- Take the B197 north through Woolmer Green and Knebworth.
- At the roundabout, join the A607 westbound toward junction 7.
Police Warn of Long Delays – Plan Ahead
Officers advise motorists to allow extra travel time or consider alternative routes where possible. This is shaping up to be a lengthy closure, so best avoid the stretch if you can.
