What we are doing
Closure of the Grand Union Canal (GUC), and alternating closure of the London Loop or towpath from February 2024. This closure will enable Align JV to construct the Colne Valley Viaduct, which will cross the GUC in Hillingdon.
On Thursday 1 February 2024, from 8am, we will close the canal and towpath in the morning and remove the existing waterpipe scaffold bridge by crane. Once this structure has been removed, we will begin the construction of the viaduct deck across the GUC using a large machine called a launching girder. This work will begin from the morning of Friday 2 February 2024 and is expected to take five weeks to complete. The canal will be closed to all boats at a point south of Harefield Marina.
