Public Consultation on M4 Smart Motorway starts

Residents, road users, local business and the local community are being invited to have their say about plans for a major upgrade to the M4.

Under Highways Agency plans, around 32 miles of the M4 between London and Theale will be widened to four lanes in each direction by converting the hard shoulder to a running lane, and installing new technology along the road to help keep traffic flowing and drivers informed.

Today, a consultation begins and the Highways Agency is keen to hear people’s views on its plans.

Highways Agency project manager, Lynne Stinson, said:

This is the biggest smart motorway project yet and will bring real benefits to drivers and the economy. It is a massive job; it will cost around £700m and involve upgrading or replacing 11 overbridges and 5 underbridges over the motorway. This consultation will set out the how we plan to deliver the improvements and we would invite anyone with an interest in the project to get involved and let us know what they think.

The consultation will run until Sunday 21 December.

The first of 11 public information exhibitions will take place at the Madejski Stadium, Reading on Tuesday 18 November, at which members of the public will be able to look at detailed plans for the proposal and also speak to members of the Highways Agency project team.

People can take part in the consultation by completing our questionnaire which will be available alongside the consultation brochure and will also be available on the Highways Agency’s website

Alternatively, a questionnaire can be requested free of charge by contacting the project team by emailing
