A5 to M1 link (Dunstable northern bypass)Recently updated

Construction of a new dual carriageway running east from the A5 north of Dunstable to join the M1 at a new junction 11a south of Chalton.

Region:  East
Start date:  February 2015
Cost:  ¬£162.1 million
Status:  COMPLETED
Type:  Major Scheme
End date:  May 2017
Programme:  

Progress report

The 2.8 mile dual carriageway A5-M1 Link (Dunstable Northern Bypass) has now opened to traffic and will become part of the A5.

The M1, which has had lane restrictions during the construction of the new road, has also now been restored to full capacity, including the use of the hard shoulder as a traffic lane at peak times. The national speed limit will apply on the new, dualled section of the A5.

The new M1 junction 11A is also open and will connect the new road and Central Bedfordshire Council’s new Woodside Link road to the M1. The road layout has changed with the introduction of new slip roads and the new junction. With the renewed use of the hard shoulder as a traffic lane, overhead message signs on the M1 will also start displaying variable speed limit messages instead of the temporary 50 mph speed.

The new road replaces a section of the A5 through Dunstable which is being handed over to Central Bedfordshire Council and Hertfordshire County Council.

Some minor work including the completion of the new sign installation will need to take place after the new road is opened and the old section handed over to the council. Single lanes will be closed for this to be done safely.

Why we need this scheme

This section of the route often experiences traffic congestion. Other local routes also carry significant amounts of traffic, including the A5120 passing through Houghton Regis and Toddington to junction 12 and the A505 linking Dunstable and Luton town centres via junction 11.

The scheme in detail

New routes

From Monday 1 August a new road layout is in place between the A505 and Dunstable Road for the A5 and Thorn Road. There is no right turn onto Thorn Road from the A5 northbound as well as no right turn onto the A5 from Thorn Road.  The northbound diversion follows the A505 to the roundabout junction with the A4146 and continues along the A4146 to where it meets back with the A5. The southbound diversion is the reverse of the northbound.

Luton Road east and west

Towards the end of last year, two new roads, Luton Road East and West, were opened to traffic. These new road layouts now allow for better travel for road users traveling to and from Chalton and Houghton Regis. It also allows for more work to be done within the closed space between Luton Road B579 and Sundon Road.

Aims

The objectives of the scheme are to:
  • reduce journey times and improve journey time reliability for long distance traffic
  • relieve Dunstable of significant congestion and through traffic on the A5
  • reduce traffic travelling to junctions 11 and 12 from the local road network in Dunstable, Houghton Regis and surrounding areas
  • boost economic growth by investing in roads to relieve congestion and improve road safety
  • provide a link between the M1 and the A5 that is critical to help economic development and jobs growth in the Central Bedfordshire area
  • unlock the development of 7,000 houses and 40 hectares of employment land ‚Äď potentially providing 4,000 jobs at Houghton Regis, whilst also improving safety on the existing A5 and local roads
