Update May 2007
The A428 Caxton Common to Hardwick opened to traffic on Thursday 24 May 2007.
These pages contain the information we published about the scheme prior to, and during, the works taking place.
The Project
The A428, together with the A421 and A14, provides an important east-west route between Milton Keynes and Cambridge.
The A428 between the Caxton Gibbet roundabout and the existing dual carriageway at Hardwick is a substandard single carriageway road that currently carries approximately 19,000 vehicles per day at Caxton Gibbet and 21,000 vehicles per day at Hardwick. It is often used as an alternative route to the heavily trafficked A14. Congestion occurs, particularly during the morning rush hour and the accident record is above that which would be expected for this type of road.
The announcement was made on 16 March 2005 that the A428 Caxton Common Scheme would go ahead. Advance works for the scheme began in June, and main construction works began in October 2005, continuing until 2007.
The A428 Caxton Common to Hardwick Improvement will provide a dual carriageway between the Caxton Gibbet roundabout and the end of the existing dual carriageway at Hardwick. It will connect to both ends of the length of dual carriageway known as the A428 Cambourne Improvement which has been built as part of the Cambourne development.
Between Caxton Gibbet and the new dual carriageway at Cambourne the scheme will run to the north of the existing road and will be 1.48 km (0.92 miles) long. The side road leading to Elsworth has been diverted as part of the A428 Cambourne Improvement.
To the east of the Cambourne Improvement the scheme will be 6.16 km (3.83 miles) long and will continue to the existing dual carriageway at Hardwick. From Cambourne it will run to the south of the existing trunk road to just before Childerley Gate, where it will cross the existing A428 before continuing on the north side to Hardwick. The existing A428 will be realigned to pass over the proposed dual carriageway. The side road leading to Bourn will be diverted and carried over the proposed dual carriageway on a bridge. A full junction allowing all turning movements will be provided at Hardwick.
Most of the existing A428 will remain to form part of a local road between Cambourne and Cambridge.
