Development Consent Order application progresses to next round of hearings

New road numbers announced for A428 scheme

A 10-mile section of new road to be delivered as part of a proposed major upgrade in Bedfordshire and Cambridgeshire is set to be named A421, as the examination process continues to progress.

When the A428 Black Cat to Caxton Gibbet improvements scheme opens in 2025/2026, the new dual carriageway will become an extension of the existing A421, which currently stops at the Black Cat Roundabout, through to Caxton Gibbet junction.

The existing A428 will also be renumbered in two sections as it changes from part of the strategic road network to become two local roads. The existing A428 will become the A1428 between Great North Road in St Neots and Cambridge Road junction. From Cambridge Road junction to Caxton Gibbet the existing A428 will become the B1428, continuing the existing B1428 which passes through St Neots further west.



The A428 scheme, which proposes a new 10-mile dual carriageway from the Black Cat Roundabout on the A1 through to Caxton Gibbet junction in addition to a number of new junctions and improvements, is currently going through its Development Consent Order examination process. The scheme, if given the go ahead by the Secretary of State for Transport once the examination process has been completed, will improve journeys between Milton Keynes and Cambridge, bringing communities together and supporting long term growth in the region.
