M4 junction 3 to 12 smart motorway - Statutory Instrument Consultation

Closed 14 Aug 2019

Opened 15 Jul 2019


We are consulting on a proposed amendment to the M4 Motorway (Hillingdon and Hounslow) (Speed Limits) Regulations 2002 No.1651.

The M4 junctions 3 to 12 smart motorway scheme involves the use of variable mandatory speed limits (VMSL) displayed on signals installed on overhead gantries – this will lead to a change in the location where the 60mph speed limit starts (currently shown by a fixed plate sign) between junction 4 and junction 3 eastbound.

VMSL gantries will displace the current 60mph fixed plate signs and a gantry cannot be sited at the current starting point of the 60mph limit due to the terms of the M4 Motorway (Junctions 3 to 12) (Smart Motorway) Development Consent Order 2016. 

An amendment is required for this change and the consultation on this page is related to this amendment only.
