A24 Mickleham Bypass, Dorking

Scheme overview

This project aims to improve the reliability and resilience of the local highway network following on from the flooding during the winter of 2013/14. This has been supported by the Coast to Capital Local Enterprise Partnership (LEP) to mitigate the effects of major flooding events in the future. This is proposed to be delivered in several phases of drainage and carriageway resurfacing improvements on the A24. Work resumed on 20 February 2017 and the scheme will conclude on 7 April 2017.

Ongoing works

We will be carrying out structural repairs and cleaning to Burford Bridge and resurfacing the Northbound carriageway between Pixham Lane roundabout and Burford Bridge roundabout.

A24 scaffolding completeBridge maintenance – 20 February to 7 April 2017

We anticipate these works to take six weeks to complete. During this time, one lane will be closed Northbound for 24 hours from just past the entrance to Dorking Wanderers football ground to Burford Bridge roundabout. Cleaning of the bridge will begin week commencing 27 February 2017. Minor repairs and repointing of the brick parapets will follow on from the cleaning. Scaffolding has been erected in order to allow safe access for the operatives to carry out the works.

Carriageway resurfacing – 9 to 21 March 2017

Our works along the Northbound carriageway from Pixham Lane roundabout to just past Burford Bridge roundabout were completed earlier than expected on Tuesday 21 March.

Works completed so far

Drainage investigations – August to December 2015

The whole length of the A24 drainage system (a network of approximately 26km) has been cleaned using a high pressure jetting system and a CCTV condition survey of the drainage network has been carried out.

Drainage improvements – February to August 2016

Location: along the Southbound carriageway from Givons Grove roundabout to Pixham Lane roundabout and along the Northbound carriageway from Pixham Lane roundabout to Givons Grove roundabout.

Following on from the drainage investigations we have completed the following drainage improvements in places at the above location:

  • repairs to defects highlighted in the CCTV condition survey
  • installation of new covers on existing gullies
  • improving the kerbing around several gullies and introducing new kerbs where needed
  • installation of new kerb weir gullies and drainage pots to provide future resilience, additional capacity for silt collection and a reserve inlet for surface water
  • installation of several catchpits to collect silt that enters the drainage system
  • construction of new recessed channel gullies to improve cleaning in the future
  • installation of soakaways to improve drainage of surface water
  • replacing top soil and grass seed.

Carriageway resurfacing – March to October 2016

Locations: Givons Grove roundabout and along the Southbound carriageway from Givons Grove roundabout to Pixham Lane roundabout. Along the Northbound carriageway from Pixham Lane roundabout to just past the Givons Grove roundabout.
