Progress report

On 28 March 2018, we issued the Notice to Proceed to our contractor, Vinci JV. This has allowed them to begin the main construction of the scheme.

The notice means that we can complete the following:

  • Phase 1 – Carefully planned site clearance with a focus on ecology. Haul road created for utilities - this has now been completed.
  • Phase 2 – Temporary diversion of the A20 to allow earthworks to be carried out for the new alignment. Work will start on the A2070 roundabout and construction elements of the new junction 10a.
  • Phase 3 –The placing of the bridge beams and deck on the main gyratory and the construction of the balancing ponds.
  • Phase 4 – Work to complete the link road between the new junction 10a and the A2070.

Kingsford Street Bridge Installation

The central span of Kingsford Street Bridge is due for installation between 8pm on Saturday 24 November 2018 and 10am on Sunday 25 November 2018. The new bridge will be located to the east of the new junction 10a and is designed for walking, cycling and horse riding.

The installation will require an overnight closure of the M20 from junction 9 to 11 coast-bound and junction 11 to 10 London-bound.

Signposted diversion routes will be in place from junction 9 to 11 coast-bound and from junction 11 to junction 10 London-bound. Road closure signage will be provided on the M25, M26 and M20, to encourage through-traffic to be diverted well away from the Ashford area.

A back up overnight closure is booked for the 8 December 2018, if the original timing is achievable, due to high winds.

For full details of the closure dates and times, see the Planned Roadworks section below.

A2070 contra-flow installation

In order for construction works on the new A2070 roundabout to take place, all traffic on the existing A2070 between Barrey Road and the Junction 10 roundabout is travelling on what is presently the northbound carriageway. Southbound traffic travels from the M20 J10 roundabout and will join the northbound carriageway for 400 metres and will re-join the existing southbound carriageway near the Barrey Road junction. For southbound traffic there will be no access to Barrey Road during this contra-flow.

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 will 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
