M3 junction 9 to 14 smart motorway

Overview

We are consulting on the proposed implementation of variable mandatory speed limits within the M3 junction 9 to 14 smart motorway scheme.

Why your views matter

The M3 motorway is a strategic route for local, regional and international traffic, and plays a major role as an inter-urban regional route connecting Southampton, Winchester and London as well as linking with the M27 motorway and routes to Portsmouth and Bournemouth.

In 2036, this section of the M3 (junction 9 to 14) is forecast to carry an average of between 63,000 and 86,000 vehicles per day, which is an increase of 20,000 vehicles compared 2015. Adding this additional infrastructure will enable forecast levels of traffic to flow freely on this section of the M3.

The scheme is part of Highways England’s programme to add capacity to the existing strategic road network in order to support economic growth and maintain mobility. It is expected that the smart motorway scheme will:

• Increase motorway capacity and reduce congestion.
• Smooth traffic flows.
• Provide more reliable journey times.
• Increase and improve the quality of information for the driver (in relation to the operation of the motorway).

The use of variable mandatory speed limits is essential to achieving the objectives above. Through the introduction of technology, we aim to make best use of the existing road space.
