Transport secretary Patrick McLoughlin attended an official start of work ceremony yesterday.

Costain-Carillion is building a 2.8 mile dual carriageway so that traffic moving between the A5 and the M1 can avoid driving through Dunstable.

A year ago, project costs were in the range of £171m to £217m. Now work has started, the cost is put at £161.2m. Last year the Highways Agency said that a neighbourijng developer was contributing £50m to project costs; that figure is now £45m.

The new two-lane dual carriageway is being built to the north of Dunstable, between the A5 (at Thorn Turn, just north of its existing junction with the A505) and the M1 at a new junction 11A (south of Toddington Services). Three new junctions will be constructed: a roundabout with the A5 at the western end of the link road; a second roundabout will be at the intersection with the A5120 Bedford Road; and a new interchange with the M1 motorway which will be named as junction 11A at the eastern end of the link road.

The scheme also includes an over bridge on Sundon Road, B579 Luton Road and the construction of four bridges passing over the A5-M1 Link.

The first phase of work will include the construction of the new B579 Luton Road east and west, temporary link roads and Sundon Road bridge.
