The Secretary of State for Transport has granted planning permission (a Development Consent Order) to National Highways to upgrade the route between the A1 Black Cat roundabout and the A428 Caxton Gibbet roundabout.

This will involve a new ten-mile dual carriageway, upgrades to the existing roundabouts, and a new junction at Cambridge Road with improved access to St Neots town centre and railway station. The Secretary of State’s decision letter is here. 

National Highways is due to start construction at the end of this year, with the road opening in 2026. Meanwhile surveys and investigations on site will continue until the end of this year before construction begins.

Online Q&A sessions and face-to-face public information events are planned for later this year, along with a mobile visitor centre. Updates will be published on the National Highways website and on social media at facebook.com/A428BlackCat and Twitter @A428Cat
