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?

This scheme is a Nationally Significant Infrastructure Project (NSIP), which means it’s classed as a large, complex infrastructure project that benefits the entire country.

To build the scheme, we need to seek permission through a special planning process and gain a Development Consent Order (DCO) from the Planning Inspectorate.

We submitted our Development Consent Order application on 26 February 2021. This follows extensive engagement with the region – we’ve met with over 4,500 people to discuss our plans and formally consulted over 5,000 people to understand their views. Visit our consultation page to find out more.

You can find out more about the examination process in this booklet and in this video by the Planning Inspectorate. The Planning Inspectorate has 28 days to accept our application and we’ll update this page at this point.

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

This video is illustrative and reflects the design at statutory consultation, July 2019.
