M20 junctions 3 to 5: smart motorwayRecently updated

We are improving the busy 6.5 mile (10.5km) stretch of the M20 between Junction 3 at West Malling and Junction 5 at Aylesford by upgrading it to an All-Lane Running (ALR) smart motorway.

Region:  South East
Start date:  March 2018
Cost:  £92.17 million
Status:  PLANNED
Type:  Major Scheme
End date:  January 2020
Programme:  

Progress report

We are currently designing the smart motorway scheme on M20 junctions 3-5 following the government’s announcement of this scheme in 2015. We have been carrying out a range of surveys and assessment work to give us information about traffic volumes and the local environment. We have also been working with local authorities and technical stakeholders so we can consider their views. This information is helping us to develop the best design solution to meet the aims we have for this scheme.

What next?

We are currently organising Public Information Exhibitions (PIEs), where you will be able to learn more about Smart Motorways, our plans for the M20 in particular, and meet members of the Project Teams.

Details of the forthcoming Public Information Exhibitions are as follows:

Why we need this scheme

The M20 is a crucial part of the UK strategic road network connecting Dover, Folkestone and the Channel Tunnel to the M25 and M26 motorways, and routes into London.

This stretch of the M20 is heavily used by cars and freight to and from the Port of Dover and the popular Kent coastal areas, especially during holiday seasons when traffic increases and congestion on the motorway occurs.

Our key issues that need to be improved on the scheme include: safety, congestion and journey times.

A large number of cars and freight travel between London and the Port of Dover, this often leads to significant congestion. This scheme is of considerable local and national economic and political importance.

There is likely to be some specific information about travelling to and from the Port of Dover, as well as diversion routes announcements in the coming months. This will include information about Operation Stack and about the impending Lorry Park in the region. Operation Stack is a procedure employed by Kent Police and the Port of Dover, to park lorries on the M20 motorway in Kent when services across the English Channel, such as those through the Channel Tunnel or from the Port of Dover, are disrupted, for example by bad weather, industrial action, fire or derailments in the tunnel.

Aims

The aims of this scheme are to improve:

  • safety
  • congestion
  • journey times

The scheme in detail

The M20 J3-5 Smart Motorway scheme will add further road space by converting the hard shoulder to a permanent running lane with additional traffic monitoring, Emergency Refuge Areas (ERAs) and variable speed message signs. The work will include:

  • four permanent running lanes in each direction, created by conversion of the hard shoulder
  • redefined junction layouts to accommodate lane gain and lane drop
  • new gantries with variable message signs and 10 refurbished message signs
  • 5 new Emergency Refuge Areas and installation of new Emergency Roadside Telephones (SOS) and CCTV cameras to improve emergency service response times
  • a hardened central reserve with a new rigid concrete barrier
  • replacement of the Teapot Lane Footbridge at Aylesford
  • replacing existing noise barriers in built-up areas and installing new barriers where necessary
  • work to maintain access to the motorway from Godstone Depot and for Traffic Officers

Construction

During the construction phase of the scheme, roadworks will be needed along this section of the M20 between junctions 3 and 5. It is anticipated that narrow lanes traffic management, temporary concrete safety barriers and speed restrictions will be put in place. In addition, junction layouts may be temporarily altered to allow for resurfacing and improvement.

There will be temporary closures of the carriageways at night on some occasions. In these instances, all updates and diversions will be clearly available and published in the appropriate section of the scheme’s webpage. Clearly signed diversions will be put in place where the work is being carried out.
