The government has announced plans for a major upgrade of the notorious Black Cat roundabout in Bedfordshire.

The junction, where the A1, A421 and the A428 meet, is currently a regular bottleneck for motorists.

As part of the project, a flyover would link the upgraded three-tier junction to a new 10-mile dual carriageway leading to the Caxton Gibbet roundabout near Cambourne in Cambridgeshire.

A1 traffic would pass under a new roundabout which would be used only by vehicles turning between the two roads.

The existing A428 would become a local road between St Neots and Caxton Gibbet.

Three options for the new road were put to the public in 2017, and the route announced on Monday is a combination of the “most popular options at consultation” according to Highways England.

A more detailed consultation is due to be announced later in the year, and work could start before April 2022.

Highways England have estimated the upgrade would cost between £810m and £1.4bn.

“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," Highways England project lead Lee Galloway said.

"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.

"With the options now chosen, we can push ahead with a more detailed design, which we will put to people for their input again later this year.”
