Road works, closures and diversions

Major new works

URGENT WORKS - High Road, Wembley - blocked sewer - Eastbound Road closure - 2 November 2017 until 22 December 2017

Update: 30 November 2017

The sewer works on High Road, Wembley, are progressing well and the proposed end date for these works is now 22nd December. 

To date Thames Water have:

  • removed the traffic Island
  • excavated a shaft onto the sewer over seven meters deep.
  • tunnelled four meters downstream, towards Park Lane, to a point where there is no concrete in the sewer.
  • tunnelled upstream, towards Wembley triangle, eight and a half meters to the lateral connection from the former Brent House site and have tunnelled a further five and a half meters but there is still concrete in the sewer. 

Next steps:

  • Sink another shaft on the sewer, this will take up to a week to complete
  • Continue to tunnel upstream to a point where there is no concrete in the sewer
  • Replace the sewer
  • Backfill the tunnels
  • Backfill the shaft
  • Permanent reinstatement of carriageway.

The end date for these works cannot be confirmed until the all concrete is removed from the sewer, having spoken to Thames Water and their contractor, Cappagh, we estimate that reinstatement works will take up to three weeks to complete from the point that all concrete is removed. It is possible that High Road will remain closed in one direction until 22 December.

Temporary traffic orders


If a closure is required a diversion route may need to be signed to assist traffic to find a suitable way around the closure and to minimise disruption.

The cost of installing, maintaining and removing diversion route signing is usually the responsibility of those organising the work. The cost will vary depending on the type of work.

The minimum notice period is ten weeks. In all cases the diversion must be agreed in advance with us and the police.
