Night closures of A412

FROM HS2

A412 Closures August – October

As you may be aware, regrettably there is a need for us to close the A412 overnight for a substantial period to build the viaduct decking across the A412. We now have a finalised set of dates and times with Bucks Council.

We understand that this may inconvenience some residents, businesses and other road users in Harefield that use the A412 between Denham and Maple Cross in the early hours, but for their own safety we cannot allow road users to pass under the girder whilst works are underway.

The road will be closed overnight from 10pm and reopened at 6am the following morning, every day (Mondays to Sundays) from Friday 19 August. Works are scheduled to end, and the road reopen 24 hours a day from 25 October 2022.
