Gulaptis praises RMS for $4m Gibraltar Range repairs

MULTI-million dollar repairs to a section of highway on the Gibraltar Range have been finished and the road is fully operational after 18 months of disruptions.

Clarence MP Chris Gulaptis said the completion of work to a section of the Gwydir Highway, west of Grafton, was finished last week.

"The NSW Government invested more than $4 million in this essential repair work," Mr Gulaptis said.

"It has been a technically complex project and having the highway returned for use by the community after 18 months is a big achievement," he said.

Two sections of the highway were damaged by landslips during continued wet weather in January last year.

This damage occurred when the mountainside under one of the highway's hairpin bends collapsed.

Due to the challenging environment, Roads and Maritime Services engineers spent considerable time undertaking detailed investigations to determine the best way to repair the damage and ensure the highway was made safe for the travelling public.

The stabilisation technique involved drilling large nails into the bedrock supporting the hillside, and further strengthening it by anchoring the nails to a reinforced concrete wall.

The project also involved clearing large amounts of soil and rock filling the damaged slope.
