The Black Cat to Caxton Gibbet scheme is a new all-purpose expressway being constructed to improve a section of the A421/A428 route that links Cambridge and Milton Keynes. It bypasses an existing section of S2 of various ages and quality. The purposes of the new road are to improve safety, separate strategic from local movements, and facilitate development on the old road, particularly at the St Neots end.
Construction started in late 2023 with the scheme due to open to traffic in 2025/6.
In September 2021 it was announced that the new route would be numbered A421, with the old road being reclassified as A1428 and B1428.
