Where was the project located?
The M25 J27 to 30 is located in Essex and for part of its 16.8 miles length forms a boundary with the Greater London Authority.  The M25 is a vital route for freight, commuter and tourist traffic.  Linking with the M2 and M20 it provides a gateway too and from the continent via Eurotunnel and Dover.

Why was the scheme needed?
The London Orbital Multi Model Study (ORBIT), published in 2002, was tasked with addressing the problems of the M25 motorway and the orbital transport corridor around London.  The study concluded that if current trends were to continue, traffic levels would increase and all users, including those essential to the economy, would suffer increasing congestion and unreliable journey times.   The ORBIT report recommended that most of the dual 3 lane sections of the M25 should generally be widened to dual 4 lanes and the work on J27-30 is part of this project.

This extra capacity will have the following benefits:

  • Improved journey time reliability
  • Reduced congestion
  • Improved motorway safety
  • Improved driver information
  • Low noise surfacing

What work was carried out?
Work completed is as follows:

  • Widened 3-lane carriageway to 4-lane carriageway in both directions (anticlockwise and clockwise)
  • Discontinuous hard shoulder at all bridges
  • Replaced central reserve
  • Provided new verge-side lighting where appropriate
  • Provided new gantries and variable message signs
  • Improved drainage, including new balancing ponds
  • Provided environmental mitigation measures

How did this benefit road users?
The traffic will move more freely with fewer delays and accidents are less likely to occur.

There will be commercial advantages, in particular having improved access around the M25 in the area of East London, Essex and Dartford.
