• M25 Junctions 5 to 7 Managed Motorways

Background

Widening of the M25 is one of the recommendations of the Orbit Multi Modal Study which reported in November 2002.  The study was tasked with addressing the problems of the M25 motorway and the orbital transport corridor around London.  The study involved widespread public consultation and looked at the current problems and potential solutions to them.

The report recommended that most of the dual 3 lane sections of the M25 should generally be widened to dual 4 lanes.

The other sections to be widened are:

• M25 Jct 16 to 23 (M40 - A1 (M)) - 21.8 miles (35 kilometres) 
• M25 Jct 27 to 30 (M11 - Dartford) - 14.3 miles (23 kilometres) 
• M25 Jct 23 to 27 (A1 (M) - M11) - 16.8 miles (27 kilometres) 
• M25 Jct 1b to 3 (Dartford - M20) - 3.1 miles (5 kilometres)
