A428 Black Cat to Caxton Gibbet Road Improvement scheme

A428 Application submitted for examination

The proposal is to upgrade the A428 between A1/A421 Black Cat Junction and A428/A1198 Caxton Gibbet Junction to high quality dual carriageway. Construction will include 19km of new Dual Carriageway, and Grade separated junctions.

We will have an interest because of changes to the Caxton Gibbet roundabout and possible impacts on traffic through the village.

The following chart shows the expected impact on traffic flows – note the increase on the volumes past Cambourne where they are forecasting a 55% increase in traffic by 2040.
