Dundas Road update

Dundas Road runs along the western edge of the High Wycombe residential area, with the airport and freight railway immediately to the west of Dundas Road. All businesses in the area remain accessible despite the section of Dundas Road being closed. The suburb of High Wycombe would not logically use Dundas Road to access the shopping centre.

The project team has met with local businesses about the implications of the sinkhole, and will continue to do so.

Dundas Road needs to remain closed until the underlying issues are identified and repair works are completed – this is for the safety of the community.

Works at the site have been ongoing since the incident occurred, with thorough investigations being carried out to determine the extent of the disturbed ground beneath the surface in the vicinity of the sinkhole.

Compaction grouting works to stabilise the ground will begin next week. This work will be completed in stages and the ground stability will be reassessed after each stage. The work may take six weeks to complete, depending on the results of the assessment of each stage.

The road repair – which will begin after the compaction grouting is completed – will be paid for by the project and is not a local government responsibility.
