Visiting Harefield Hospital

Harefield Hospital is situated in extensive grounds in the countryside just outside London. It is close to the M40, the M25 and within easy reach of Heathrow airport and has ample car parking.   

May to July 2019 road closures

Due to the construction of a new access road, closures will take place on Breakspear Road South between May and July 2019.

We understand that this affects both the public and local community, so we have scheduled the work to be completed in three phases. This is to minimise any disruption and inconvenience that may be caused. The road will be closed:

Phase 1: Friday 31 May - Thursday 27 June

The road will be fully closed from 6am on 31 May until 8pm on 27 June.

Phase 2: Thursday 27 June - Friday 12 July

The northbound lane of Breakspear Road South will be closed from 8pm on 27 June to 6am on 12 July. Traffic will still be able to use the southbound lane via traffic light control. Delays are expected and we recommend people use the diversion. 

Phase 3: Friday 12 July - Sunday 28 July

The road will be fully closed from 6am on 12 July to 8pm on 28 July. 

Monday 29 July 2019

Breakspear Road South will fully reopen. 

Why this work is being done

This work is to complete the construction of the new access road for Merck, Sharpe and Dohme (MSD), along with re-positioning of various utility and service connections a full road closure on a section of Breakspear Road South is required. Access will be maintained to residential properties at all times. Due the size of the excavation required for these works and the narrow nature of Breakspear Road South (BRS), the safest and most effective way to deliver these works is by fully closing the road.  Many of the utility and service connections span the full width of the road. The closure will allow Costain Skanska to ensure the safety of the public and our workforce.

The works that we will deliver within this closure period include the:

  • construction of the new MSD access road junction with Breakspear Road South
  • construction of a new pedestrian crossing to accommodate the bridleway diversion
  • installation of a new telecoms, water main and gas connections
  • diversion of high voltage power cable route
  • disconnection of a number of redundant utility supplies
