A HUGE boulder, weighing up to 100 tonnes, has been anchored in place by metal rods and cables above Blueskin Rd, at Careys Bay, Dunedin.

Dunedin City Council group manager transport Jeanine Benson said contractor­s had also added extra ballast to four shipping containers positioned to protect houses at Careys Bay, below the site.

Workers would today turn their attention to constructi­ng an earth bund below the boulder, also to hold it in place.

The aim was to finish the bund tomorrow and break down the rock in time to reopen Blueskin Rd on

Friday, Ms Benson said.

Contractor­s would drill into the boulder to split it into fragments small enough to be removed, she said.

Other options, including using explosives to demolish the boulder and a temporary reopening of the road for limited hours in the meantime, were not considered viable or safe.

Staff and contractor­s were working as quickly as possible, and the inconvenie­nce to motorists and residents from the road closure was regretted, but public safety was paramount, she said.

The boulder was made of a type of rock known as breccia, also known locally as ‘‘Port Chalmers rock’’.
