M3 junctions 9 to 14: smart motorwayRecently updated

Upgrading the M3 between Junction 9 (Winchester / A34 interchange) and Junction 14 (M27 Southampton interchange) to an All-Lane Running (ALR) smart motorway. The scheme was announced in 2015 by the government, and will link to the smart motorway scheme on the M27.

Region:  South East
Start date:  31 March 2020
Cost:  ¬£139m
Status:  PLANNED
Type:  Major Scheme
End date:  31 March 2022
Programme:  Smart Motorways

Progress report

We are currently designing the smart motorway on the M3 located in Hampshire between junctions 9 and 14. The scheme was announced in 2015 by the government, and will link to the smart motorway scheme on the M27.

We have begun discussions with local authorities and technical stakeholders.

What's next

We will continue our design work and environmental assessments along the route, and commence engagement with local authorities, environmental bodies, local businesses, strategic traffic users, and emergency services.

Please sign up to our email alerts to keep updated about the scheme, as well as planned public events, and to learn more about the smart motorways programme.

Why we need this scheme

The M3 is located in Hampshire, and falls within the Highways England Area 3 Asset Support Contract, as well as the South East Regional Control Centre. It is a key part of the strategic road network, providing a vital transport link to London, south Hampshire via the M27 Southampton interchange, and the midlands via the A34.

The M3 junction 9 to 14 is a crucial route connection for the Solent to Midlands, and Solent to M25 routes. The A34 is linked to the M27 by the M3 junction 14 at Eastleigh to junction 9 at Winchester. The route serves the ports of Southampton and Portsmouth, Southampton Airport, and the wider Solent region.

This route is heavily used by cars and freight, and faces congestion during peak travel hours caused by the volume of traffic using the network.

Aims

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

The scheme in detail

The M3 smart motorway stretches from junction 9 (Winchester / A34 interchange) to junction 14 (M27 Southampton interchange). The scheme is 13km (8 miles) long.

The scheme includes:

  • junction 9 to 13 upgraded to a smart motorway, All-Lane Running
  • junction 13 to 14 to a controlled motorway
  • junction 14 to M27 link road to a controlled motorway

The scheme will involve:

  • 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 areas throughout the length of the scheme
  • safe area located on junction 11 and 12 slip roads
  • the hardening of the central reserve and installation of a reinforced barrier to improve safety
