Departmental delivery commentary

The SRO Delivery Confidence Assessment (DCA) rating remained Green in Q4 25/26, consistent with the position reported in Q4 24/25. The A428 Black Cat to Caxton Gibbet scheme passed the halfway point of its construction phase at the start of Q3 25/26 and continues to perform in line with agreed delivery commitments. Construction activity is progressing well across all key locations, including the Black Cat junction upgrade and the opening of new local junctions and route improvements. There have been no changes to the approved cost or benefits forecasts, and the scheme remains on track to deliver within the agreed funding envelope.
