Night closure of A412 North Orbital Road, between West Hyde and Denham

What we are doing

We will be carrying out road resurfacing works, including the removal of temporary construction assets. To undertake these works safely, a full road closure will be required during the stated hours.

Location
A412 North Orbital Road, Denham, Uxbridge.

Duration
The road will be closed from 10:00pm to 5:00am from Monday 29 June to Saturday 4 July 2026. A single lane closure with traffic management will be in place from Saturday 4 July to Friday 10 July 2026.

What to expect
Phase one will require a full road closure. A signed diversion route will be in place, along with advance warning signage positioned at both ends of the closure to help guide road users. Following this the road will remain open with temporary two-way traffic signals installed to safely manage traffic movements through the area until works are complete.

HS2 is undergoing a comprehensive reset to ensure it can be built efficiently and for the lowest reasonable cost. This work is being carried out in stages and will be completed in 2026. We will provide you with updates on the reset and what this means for our plans to build the railway in your area.
