Digging down

Waitaki District Council contractors carry out excavation work in lower Thames St near the intersection with Steward St in Oamaru yesterday, to determine the cause of slumping in a small section of the busy street. 

Acting council roading manager Mark Renalson said the work had revealed a flow of water into the site which needed further investigation to identify the source before it could be rectified.

The work was expected to take about a week.

One lane of the two-lane northbound road will remain closed for the duration of the project.
