Building the Colne Valley Viaduct

We wrote to residents in the Colne Valley in December 2020 to explain the preparations we have been undertaking for the construction of the Colne Valley Viaduct. The viaduct will be over 2 miles long and will span several lakes in the Colne Valley from Harvil Road in Hillingdon, crossing through a section of Hertfordshire, near West Hyde, to the northern embankment at Shire Lane, in Buckinghamshire.

In March 2021 we will start to build the viaduct at our compound next to the A412 in Denham, Buckinghamshire. We will work across the Colne Valley from north to south, using our system of internal haul roads, works compounds and signalized road crossings to keep HGVs off local road network wherever possible.

We will keep residents and businesses updated on the progress we are making, providing notification of any impacts that our work may have. The information in this notification is intended to give communities in the Colne Valley an overview of how and where the main construction activity will take place over the next 2-3 years.
