The Cunningham Highway is part of the federally funded national network providing a crucial east–west connection between Ipswich and Warwick for industry, tourism, businesses and the community.
Up to 5000 vehicles use the Cunningham Highway daily, many of them heavy vehicles.
The department started urgent safety works in November 2010 to manage the risk of major rock falls at Cunningham’s Gap.
Between December 2010 and early March 2011, the Gap received more than 2m of rain. Cunningham’s Gap sustained an enormous amount of damage as a result of this. Work to repair this damage was essential to the safety of Cunningham Highway road users.
Details of project features
The major reconstruction work required at 11 sites through the Gap included slope stabilisation works, drainage works, pavement repairs, new guardrails and asphalt sealing. The most badly damaged site was Clayton’s Gully.
Nearly 130,000m3 of material had to be excavated during the works at Clayton’s Gully and 20,000 tonnes of asphalt have been laid at the various sites to provide a new road surface through the Gap.
