Colne Valley viaduct landscaping and causeway removal works

What we are doing

From the North Embankment of the viaduct to the west of the A412 and Korda Lake, we have begun landscaping around the viaduct piers and the removal of parts of the internal haul road, between the River Colne and the removal of the internal causeway between the River Colne and Korda Lake. We will be constructing a culvert near to the old Denham Waterski Club building to improve permanent land drainage in this area.

To create the walls of the culvert, we will need to drive metal sheet piles into the ground. This will generate noise that may be heard by businesses and residents nearby. We will be monitoring the noise levels to ensure we do not exceed agreed levels.

Piling will start on Monday 24 June and is due to complete by Friday 5 July 2024. Hours of work are 8am to 6pm Monday to Friday only.

The causeway removal works will continue through to October 2024 and again will generate some noise but will be kept within agreed levels.

From July 2024 through to December 2024 works will take place to remove the jetty across Korda Lake and Long Pond. We will write to local stakeholders with details on these works later this month.

Hours of work for both causeway and jetty removal works are Monday to Saturday 8am to 6pm.
