Construction of a new single two-lane road to carry the A120 around the northern edge of the village of Little Hadham. At present the A120 passes through the village and along a length of narrow road that is single file and operates with traffic signals to alternate traffic flows.

The new bypass will connect to the existing A120 with a roundabout at either end, and will have no other connections to other roads.

Construction of a new bypass to the south-east of Baldock,to dual-two lane dual carriageway standard, partially grade-separated. It will connect the A505 dual carriageway east of Baldock to the A1(M) at junction 9. A 230m cut-and-cover tunnel will carry the new road under a hill near Clothall to preserve the profile of the local geography. This is now known as the Weston Hills tunnel.
