Details

This is the interim, first stage evidence, report for the M25 south-west quadrant study. It outlines the high level case for improvements to the M25 south-west quadrant and it will inform further work being carried out to develop the options for intervention.

The report finds that:

  • the study area is economically prosperous with a strong, highly skilled labour market
  • the study area faces regular severe congestion and increasingly unreliable journey times which could risk the competitiveness, attractiveness and economic growth aspirations in the local area.
  • given the complex nature of travel movements in this area, it is unlikely a single option dealing with all issues to an acceptable level will be found

Background to the M25 south-west quadrant strategic study

The M25 south-west quadrant strategic study is one of 6 strategic studies that will inform the development of the second phase of the Road investment strategy (RIS 2).

The study was announced as part of the first phase of the Road investment strategy (RIS 1) published in December 2014. The RIS 1 and RIS 2 set out a long-term approach to improve England’s motorways and major roads (the ‘strategic road network’).
