We are proposing to upgrade the route between the Black Cat roundabout and Caxton Gibbet roundabout with a new 10-mile dual carriageway and a number of junction improvements. The scheme will improve journeys between Milton Keynes and Cambridge, bringing communities together and supporting long term growth in the region.

What’s happening now?


In summer 2019, we consulted on proposals for the new dual carriageway and junction improvements. We listened to your feedback and as a result have improved the scheme design, making changes to our proposals. Many of these will help minimise impacts on the environment and local communities. We consulted on these changes in June and July 2020.

Your feedback will inform the development of the scheme before we submit our application for planning consent. As part of our application, we will also publish a Public Consultation report summarising the feedback on our proposals.

The best way to find out about our 2020 consultation is to visit our virtual room. Alternatively, go straight to the online survey or download materials.

Watch our fly-through video showing you our proposals for the scheme.
