M27 Smart Motorway

Highways England is creating a smart motorway on the M27 between junctions 4 to 11. This means that the hard shoulder will be turned into a permanent running lane, converting it into a dual four lane smart motorway. New signage and technology will be introduced to help with the management of vehicle speeds and safe lane use.

Aims of the scheme

Reduce congestion and smooth the flow of traffic by turning the hard shoulder into a permanent running lane
Improve journey time reliability on the strategic road network
Support the economy and facilitate economic growth by providing increased capacity on the motorway
Continue to deliver a high level of safety performance on the network using Smart Motorway techniques
Minimise environmental impacts of the scheme and where possible allow for enhancements to be made to the environment

What the scheme involves

Permanent conversion of the hard shoulder to create a fourth lane and changing the junction slip roads to accommodate this
New CCTV cameras and electronic information signs and signals on gantries - these will show variable mandatory speed limits and manage traffic flow and incidents
Emergency refuge areas throughout the length of the scheme
The hardening of the central reserve and installation of a reinforced barrier to improve safety
