M20 junction 10a

A new junction 10a and link road to the A2070.

Region:  South East
Start date:  January 2018
Cost:  £104.4 million
Status:  CURRENT
Type:  Major Scheme
End date:  Summer 2020
Programme:  

Progress report

A traffic management switch, where the A2070 link road and the coast-facing slip roads were completed and were available for traffic, was completed on 31 October 2019. As part of the improvement works for the junction 10a scheme, the east-facing existing slip roads of junction 10 (also referred to as the London-bound exit slip road and coast-bound entry slip roads) are being closed from the evening of 13 November 2019. This is due to the newly completed west-facing slip roads joining the M20 at junction 10a being operational.

The new layout now means that:

  • traffic on the London-bound carriageway that wishes to leave the M20 in the region of junction 10, will do so at the new junction 10a off-slip
  • traffic wishing to enter or exit the M20 at junction 10 using the coast-facing slip roads will now use junction 10a

What's next?

Throughout November and December, we’ll be continuing to finish key parts of the project and reopening sections of the road to traffic. Works will include:

  • closure of junction 10 coast-facing slip roads
  • opening of new junction 10a London-facing slip roads
  • opening of segregated left-turn lanes on the A2070 roundabout

Why we need this scheme

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.

We predict that the existing M20 junction 10 would suffer from congestion and long delays in the future if additional capacity is not created.

We have identified the scheme as 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.

The scheme in detail

We announced our recommended design for this scheme, referred to as our “preferred route”, in 2010. When we decided on this route we took into account the feedback you gave us during our public consultation in 2008.

For the preferred route we will construct a new M20 junction 10A, 700 metres south east of junction 10. The new junction will include the following:

  • a new roundabout over the motorway
  • new slip roads
  • a new link road to the A2070 Bad Munstereifel Road, with traffic signals on parts of the junction and two 3-lane bridges
  • removal of the east facing slip roads at the existing junction 10
  • A20 Hythe Road incorporated in the new junction so that the traffic in both directions can travel via the new roundabout
  • a new pedestrian and cycle bridge over the M20 from Kingsford Street to the A20, demolishing the existing Highfield Lane Bridge
  • replacement of Church Road footbridge over the A2070

The preferred route is protected from development. This means other organisations won’t be able to make changes to the area before the scheme begins, eg utilities. You can view our preferred route announcement leaflet. 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 available.

Aims

The aims of this scheme are to:
  • provide infrastructure to support development in the Ashford area
  • help separate long distance traffic from local traffic
  • reduce congestion and improve journey time reliability
  • improve road safety
  • improve noise and air quality for properties to the west of A2070
  • provide safer crossings over the M20 for pedestrians and cyclists via a new footbridge
