We’re 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 proposed scheme is estimated to cost between £810 to £950 million and, if given the go ahead, will improve journeys between Milton Keynes and Cambridge, bringing communities together and supporting long term growth in the region.

What’s happening now?
The examination phase for the A428 Black Cat to Caxton Gibbet scheme has formally closed. Over the next few months the Examination Authority (appointed by the Planning Inspectorate), who have been scrutinising the scheme during its formal public examination, will carefully consider all the evidence they’ve heard, including the many questions and representations from the public and local authorities.
They will then recommend whether the Secretary of State for Transport should grant formal planning permission (a Development Consent Order), so construction can begin. Following receipt of the Examining Authority’s Recommendation Report, the Secretary of State will decide on whether to grant or refuse development consent. We expect this decision to come later in the summer. The full Examining Authority’s report won’t be published until the decision is made.
This short video shows how road schemes are developed from instruction to construction.
