What is happening?

We are proposing to provide a new M20 Junction 10A and link road to the A2070 at Ashford in Kent with a new dual carriageway link road to the existing A2070 Southern Orbital Road (Bad Munstereifel Road) and also connect to the A20 Hythe Road.

The Secretary of State for Transport announced the Preferred Route in March 2010 after considering the views of those who responded to the consultation and our recommendations. This comprises the following:

  • Constructing a new M20 junction 10A, 700 metres south east of junction 10. The new junction will include a roundabout over the motorway, new slip roads and a new link road to the A2070 Bad Munstereifel Road. Junction 10A will be partially signalised with two 3 lane bridges
  • Incorporating the A20 Hythe Road in the new junction so that the traffic in both directions would travel via the new roundabout
  • A new pedestrian/cycle bridge over the M20 from Kingsford Street to the A20.
  • Demolishing the existing Highfield Lane Bridge and Church Road footbridge
  • A new non-motorised user crossing at Church Road
  • Removing the east facing slip roads at the existing junction 10

The preferred route is protected from development. You can view the Preferred Route Announcement Leaflet under  Publications.

We have also produced a Scheme Assessment report and Public Consultation report explaining the factors that determined the choice of the scheme. If you would like to receive a copy of these reports please use the contacts below.

When and where is this happening?

The Spending Review announcement in October 2010 listed the M20 Junction 10A scheme for potential construction in future spending review periods, subject to the outcome of statutory processes, and one of four schemes to be reviewed.

The scheme review is now complete.  In May 2012 Ministers announced a number of schemes which would now have their pre-construction development works funded to prepare them for potential construction early in the next spending review period.  M20 Junction 10A was not one of these and so remains in the future programme.  Future Spending Review page.

The new interchange will be on the M20, approximately 700m to the east of junction 10, between Ashford and Folkestone in Kent.

Why is this happening and what will it cost?

The scheme will support the development of Ashford. The existing M20 Junction 10 will suffer from congestion and long delays in the future if additional capacity is not provided. The M20 is an international route and is used by large volumes of heavy goods and holiday traffic. Long distance traffic from the M20, A20 and A2070 (south of Ashford) conflicts with local traffic from Hythe Road and Kennington Road.

The M20 Junction 10A scheme has been identified as a key transport requirement and is essential to the future development of South Ashford. The recent improvements at Junction 10, to increase the capacity and improve safety, will allow some development to go ahead but will not be sufficient for all of the proposed developments

How will the scheme be carried out?

This scheme is still at the planning and design stage; more information about how the scheme would be carried out will be added here as it becomes available.

What are the benefits?

The provision of junction 10A is pivotal to the future development of South Ashford, which has long been identified in both structural and local plans as the focus for growth and expansion in Ashford. Our proposals will:

  • Provide infrastructure to support development in the Ashford area.
  • Help separate long distance traffic from local traffic.
  • Reduce congestion and improve journey time reliability and road safety.
  • Improve noise and air quality for properties to the west of A2070.
  • Provide a safer crossing facility over the M20 for pedestrians and cyclists via a new footbridge.

Report

During our preliminary design work we considered a number of scheme options. These include improvements to the existing Junction 10 and other options for a Junction 10A.

Discounted Option 1 - Further Improvements to the Existing Junction 10

The estimated cost for this option is less than the proposed option and there is no major impact on properties near Highfield Lane Bridge.

However, it is difficult to construct and some elements of recently completed works would be demolished.

There is greater disruption and impact on properties near the A2070.

The complex signing and signals are likely to cause major traffic and safety problems and capacity would be reached sooner than with a new Junction 10A option.

 

Discounted Option 2 - A Single Bridge Junction 10A

The estimated cost for this option is slightly less than the proposed option but there is greater impact on properties near the A2070.

There is less capacity than with the proposed option and also less scope for improvements in the future.
