I have been advied of a project due to start on 18th May as part of SES Waters resilience plan set by OFWAT. The works will link a pipe already in the Tesco car park to an existing pipe at the Dale Road junction (junction between Warren Road / Downs Court Road junction and Foxley Hill Road, northern junction). These pipes will then allow Kenley and Woodmansterne water works to serve one and other if either were to suffer a break down, particularly Kenley with the threat of the Bourne.
Unfortunately the works will require a road closure of the A22 in both directions for 6-8 weeks from the Warren Road / Downs Court Road junction to outside the old My Old China site / Tesco entrance.
The finer details, e.g. how traffic will be managed, have yet to arrive but I will share this once received.
UPDATE: The communication of this road closure was so poorly conducted that it was decided that the work, and road closure, would not take place until 2021.
