A23 Redhill and Horley drainage improvement works

Scheme overview

The A23 Local Enterprise Partnership (LEP) project began in early January 2018 and aims to improve the drainage and resilience of sections of the A23 network following on from the flooding during the winter of 2013/14. This project is being partly funded by the Coast to Capital 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 resurfacing.

Some of the benefits of the works include:

  • Improving the overall road safety for vehicles, pedestrians and cyclists
  • Helping to reduce the likelihood of surface water flooding
  • Prolonging the life of the carriageway
  • Helping to deliver economic prosperity in Surrey

Improving the road conditions for the new shared pedestrian / cycle path and bus stops.

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 can be found above.

What hours will you be working?

During the day we will be working off-peak between 9:30am and 4pm. Most work will carried out on weekdays however there may be weekend working. During the night we will be working between 8pm and 6am (weeknights only).

Why are you not working at night or at the weekend?

Night or weekend working significantly increases the overall cost of a project and it will therefore be unaffordable to complete the scheme within the current budget.

Will there be any road closures required?

The resurfacing work will require a road closure at night. The traffic management required for the drainage improvement works will be lane closures and/or temporary traffic lights.
