A5 before and after
During planned general utility upgrade works at the junction of the A5 and Station Road, Edgware, a void under the road was discovered.
For safety reasons, the Southbound carriageway was shut after the junction – introducing a contraflow system on the Northbound carriageway to minimise disruption in the area.
Before repairing the void, the council had to wait for various utility companies to carry out integrity checks on their below ground network – this was essential to ensure their network was not damaged or caused the void.
In some cases, these investigations required the use of specialist inspection teams, further delaying their completion.
Due to the nature of the void and the proximity of the utilities network there could be no quick fix.
Repairing the void could only commence after these investigations due to the possibility of certain engineering techniques being unable to be used.
Once complete, a permanent repair to the void was worked on as quickly as possible.
Works were completed yesterday afternoon (3 November 2022), with the southbound carriageway reopened.
The council would like to thank all residents, businesses and road users for their patience.
