A special “spider excavator” has been hammering in about 300 giant nails during the latest Noah Range roadworks project in the Daintree Rainforest region.

Project manager Michael Bowler said the spider excavator used long arms to anchor to the steep surface in order to insert the up-to-12m-long nails.

“The rest of the slip will then be terraced and revegetated to create further stabilisation,” Mr Bowler said.

Stabilisation works are expected to be completed by March, after which the road surface will be rebuilt.

Douglas Shire Mayor Lisa Scomazzon said the works were a vital part of protecting the region from future weather events.

“We’re committed to ensuring long-term safety and access for our communities, and this work is a strong investment in the resilience of our road network north of the Daintree River,” Mayor Scomazzon said.
