We're using a new way to keep everyone safe while we install roadworks on the motorway.

We're using a specialist vehicle that creates a temporary work zone on the road. This zone is traffic-free for about 9 minutes at a time.

While we work, traffic can still move at around 10mph rather than being stopped completely. Journeys may take a bit longer than usual, but drivers won't face the long delays that traditional closure methods can cause.

This new method helps us:

• Keep our road workers safer
• Keep traffic moving instead of creating long delays
• Finish our work more quickly
• Reduce pollution from vehicles stuck in traffic
• The specialist vehicle also has a digital warning system. This alerts our workers if any vehicle accidentally enters the protected work area, helping keep everyone safe

Please remember that closures can change at short notice. You can check the latest information on our daily closures page or find live travel information on our Traffic England site. Our travel alerts give details of live incidents on our network.

We'll keep three lanes open in each direction with a speed limit of 50mph for most of our works
