What we are doing

From Monday 23 June 2025 our vehicles will no longer cross the A412 where the viaduct goes over the A412 North Orbital Road near Denham Waterski Club. This was part of our internal haul road to keep HGVs off the A412. We will now use the road used by Affinity Water to access their facility off the A412 as well as Denham Waterski Club. Vehicles using this entrance will be eight-wheel HGVs, tipper trucks and pick ups as well as the removal of any large plant once landscaping works are completed later this year.

From Monday 14 July to Friday 25 July 2025 works will take place to remove the traffic lights which managed the haul road crossing, as well as work to remove the bellmouths each side. This will be managed 24/7 with temporary two way traffic lights. Below is a map of the works taking place and new access point off the A412.
