The Brampton Hut interchange links the A1 and A14 road west of Huntingdon. The A1 passes over a grade separated roundabout which provides access to the A14 and a comprehensive service station. East and west traffic on the A14 uses the roundabout to join the A1 southbound and to continue on the A14. Traffic from the A14 East and wishing travel north would have previously used the A14 northern spur to access the A1(M) at Alconbury.
