The Project
The A421 Great Barford opened to traffic on Thursday 24 August 2006. These pages contain the information we published about the scheme prior to, and during, the works taking place.
The Great Barford Bypass is a new 7.7kms (4.8 miles) long dual carriageway. It commences at the eastern end of the Bedford Southern Bypass. The existing roundabout was removed and the dual carriageway continued in a north easterly direction beneath Water End Road, where a new two level junction was built to allow all turning movements on and off the Bypass. The route runs to the north of Great Barford and Roxton, connecting into a new enlarged Black Cat Roundabout on the A1.
Bridges were provided for Barford Road, Birchfield Road and Roxton Road to cross the Bypass. There were also additional underpasses or bridges for watercourse crossings, access requirements for the landowners and safe crossings for footpath and bridleway users.
