In a project that will improve a key east-west road link, journeys on the A1, the A421 and the A428 will be improved by a new three-tier junction at the Black Cat roundabout in Bedfordshire, which will allow drivers to pass through the junction uninterrupted, while keeping the roundabout clear for drivers making turns between the roads.
And a brand new, 10-mile dual carriageway will link directly between the upgraded Black Cat junction and the Caxton Gibbet roundabout near Cambourne in Cambridgeshire, with a new junction at Cambridge road and new bridges. The existing A428 will become a local road serving communities between St Neots and Caxton Gibbet.
Highways England project lead Lee Galloway said:
"This major new dual carriageway between St Neots and Cambridge and upgrade for the Black Cat junction will mean quicker and safer journeys for people and will also boost the economy and unlock housing. As well as significant improvements locally, the project will be a vital component in improving the regional and national road network. The improvements will complement our £1.5bn A14 upgrade and form part of a wider transformation of road links between Cambridge, Milton Keynes and Oxford."
