This from HS2:
Closure of Breakspear Road South – 31 May to 29 July
Posted on May 13th 2019 by HS2 in Hillingdon
We are continuing HS2 preparatory works in your area. As part of this work we need to close a section of Breakspear Road South to safely complete the construction of the new Merck, Sharpe and Dohme access road, along with re-positioning and reinstalling of various utility and service connections.
We recognise road closures affect both the public and the local community and will cause significant impacts on your journey plans. We have scheduled the work to be completed in three phases, which we explain fully below.
Phase 1: Full road closure for 27 days, starting Friday 31 May at 6am to Thursday 27 June at 8pm.
Phase 2: Northbound lane closure for 17 days, starting Thursday 27 June at 8pm to Friday 12 July at 6am.
Phase 3: Full road closure for 16 days, starting Friday 12 July at 6am to Sunday 28 July at 8pm.
Full reopening of the road on Monday 29 July 2019.
We encourage all drivers to follow the advised diversion route shown in the notification. A detailed map will be available shortly. The notification sent to residents can be found here.
The closure will begin north of the Merck, Sharpe and Dohme entrance and end after Gatesmead Farm. Access will be maintained to residential properties at all times.
