The Department of Transport and Main Roads (TMR) plans to start work in mid 2014 on two landslips on Nerang-Murwillumbah Road, Natural Bridge.
The two sites are located 34 kilometres from the start of the road at Nerang, past Bakers Road, Natural Bridge. See attached map. Both landslips occurred in late January 2013 and were caused by heavy rainfall associated with ex-tropical Cyclone Oswald.
The design solutions to stabilise the two slopes are different. One of the landslips (site 29) requires geotechnical repair works and the other landslip (site 23) will be revegetated.
Work at both sites is expected to be complete by mid to late 2014, site and weather conditions permitting.
After the landslip occurred at site 29 in January 2013, an inclinometer (a remote geotechnical sensor) was installed to monitor the ground conditions.
From mid April 2014, further ground condition investigations and survey work may be required. No traffic impacts are expected from these preliminary works.
This project is part of the region’s program of flood related repairs. TMR are seeking funding to deliver six of these landslip projects under the National Disaster Relief and Recovery Arrangements (NDRRA), a joint federal and state initiative. Eligible reconstruction works under NDRRA are funded up to 75% by the Australian Government and 25% from the Queensland Government.
A budget of $3.4 million has been allocated to these works.
