What we are doing
Update: These works have now been completed ahead of schedule and the road re-opened on Monday 25 September 2023.
The decking of the Colne Valley Viaduct over the A412 has already been completed, however we now need to work over the road to install parapets – walls either side of the viaduct. To complete these sections safely over the public highway we need to close the road to all users. For the safety of pedestrians and road users during the works, the A412 will be closed to pedestrians and all through traffic between Chalfont Lane, West Hyde and Moorfield Road, Denham Green – Monday to Saturday, from Monday 4 September to Friday 29 September between 10pm and 5am.
