M27 junctions 4 to 11: smart motorway
We're converting the M27 between junction 4 (M3 interchange) and junction 11 (Fareham) by turning the hard shoulder into a permanent running lane, making a dual four-lane motorway.
Project information
The M27 smart motorway scheme stretches from junction 4 (M3 Interchange) to junction 11 (Fareham), and will directly connect to the M3 junction 9 (Winchester / A34 Interchange) to junction 14 (M27) smart motorway scheme. The scheme is 24km (15 miles), and all links on the M27 between junction 4 to 11 will be upgraded to smart motorway, dual four all-lane running. The hard shoulder will be retained between junctions 7 and 8.
The scheme will involve:
- 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
The aims of this scheme are to:
- 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
