The A1 Trunk Road (Tempsford Junction Improvements Slip Roads) Order 1999 authorised the construction of new slip roads to access the A1 and the scheme was completed in 2001. A slip road from the southbound carriageway joins the road from Little Barford, which was extended south through Tempsford Hall Park to a new roundabout. A bridge across the A1 and a second roundabout were built to access the northbound carriageway and the roads to Blunham and Church End. The road to Church End became a no through road.
