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 negotiating an agreed target price to begin construction on the scheme to ensure value for money for our customers.

We recently completed a Public Information Exhibition where local members of the public learnt about our proposals for the scheme, how the works will be carried out and what measures are in place to mitigate concerns such as noise pollution. Further information regarding the Public Information Exhibitions can be found on the publications and media tab.

What next

We will be preparing the site to start construction between December 2017 and March 2018. This will help with the delivery of the main construction works beginning in March 2018 and expected to be completed in September 2019.

Why we need this scheme

The M20 Junctions 3 to 5 forms part of a principal route that provides key links via Dover and Folkstone ports and Channel Tunnel to and from mainland Europe. As such, it facilitates national, regional and local travel, and regeneration and growth. Furthermore, the route provides critical access via the M26/M25 to London, the airports of Heathrow and Gatwick and to the wider South-East, South-West and the Midlands.

The M20 between Junctions 2 and 3 has the lowest journey time reliability measurement of 65.9%. With forecast annual traffic growth of 4.17% in cars and 2.79% in HGVs, the time reliability measurement is going to get worse if Do Nothing is the option to address this issue. Introducing a smart motorway between Junctions 3 and 5 is identified as the most economic and efficient solution to reduce congestion, add capacity whilst ensuring the safe operations of the motorway. There will be utilisation of up-to-date technology to smooth traffic flow and enhance journey time reliability.

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 for the majority of the scheme, created by conversion of the hard shoulder
  • redefined junction layouts to accommodate lane gain and lane drop
  • new and refurbished 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 deck at Aylesford to accommodate the hardshoulder conversion to a running lane
  • replacing existing noise barriers in built-up areas and installing new barriers where necessary
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.
