Work on National Highways’ much-delayed £1bn A428 Black Cat to Caxton Gibbet scheme finally began this week.
The scheme will see the creation of a new 10-mile dual carriageway linking the A1 and A421 Black Cat roundabout in Bedfordshire to the A428 Caxton Gibbet roundabout in Cambridgeshire.
Both existing roundabouts will be upgraded into free-flowing junctions with a new junction added at Cambridge Road, improving access to St Neots and its train station.
National Highways said the new dual carriageway will also remove the temptation for drivers to use local roads to avoid delays, removing up to 4,000 vehicles from these routes.
Transport minister Anthony Browne broke ground on the project to mark the main start of construction.
Nicola Bell, National Highways executive director for major projects, said: ‘As we break ground today, we embark on a journey that will transform transport in this region, easing congestion, improving connectivity, and fostering economic growth.
‘This project highlights National Highways’ commitment to delivering major projects that make lasting impacts for people, communities, and businesses. The start of construction represents a culmination of meticulous planning, collaborative efforts, and a steadfast commitment to enhancing the nation’s infrastructure.'
Project director Lee Galloway said: ‘This project is about connecting communities and leaving a positive legacy in the region. Throughout construction, we are committed to bringing the community on the journey with us, minimising disruption, and ensuring that local people and businesses remain an integral part of the process.’
The scheme, which was part of the first (2015-20) Road Investment Strategy but has been subject to repeated delays is now expected to open to traffic in Spring 2027.
