A31 Local Enterprise Partnership (LEP) Project

Page contents

Scheme overview

The A31 Local Enterprise Partnership (LEP) project has been in the planning and development process for a number of months and aims to improve the drainage and resilience of sections of the A31 network (including some vegetation clearance). This project is being partly funded by the Enterprise M3 LEP and the objective is to mitigate the effects of major flooding events in the future. The project is being delivered in several phases some of which include drainage improvements, repairs and carriageway surfacing.

Some of the benefits include:

  • Improving overall road safety for road users
  • Reducing the likelihood of surface water flooding
  • Prolonging the life of the carriageway
  • Helping to deliver economic prosperity in Surrey

Frequently asked questions

It's a very long road, how are these works going to be carried out?

The works will be carried out in sections and the anticipated dates and locations will be published on this website prior to works commencing.

What hours will you be working?

Most of our drainage works will be carried out during the day time under lane closures. Works will take place from 7:30am to 5:30pm Monday to Friday and 8am to 5pm on Saturdays.

The lane closures will remain in place 24 hours a day for the duration of the works. There may be some road closures required on surrounding roads to facilitate the works on the A31.

Advanced notice will be provided on this web page and via advanced warning signs and leaflets prior to any closures needed for these drainage works.

Will there be any road closures required?

Road closures will be required for the surfacing work. We will try to limit the disruption these closures will cause by undertaking this work on weeknights.

Most drainage improvement works will be conducted under lane closures during the day.
