The stage 3 report for the M25 south-west quadrant strategic study recommends focusing on how to:
- reduce pressures
- provide parallel capacity
to relieve the motorway network rather than widening existing roads.
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’).
