Abstract
Lawrence Hargrave Drive is a spectacular section of coast road just north of Wollongong. It has had a long history of closures due to geotechnical instability. Community disruption as a result has been a feature of life in the vicinity.

In August 2003 the Minister for Roads announced that the road would be closed for two and a half years to enable a safe, permanent solution to be constructed.

Not only was the time-frame almost impossibly short, but the technical challenges were daunting. The environment is one of the most aggressive one could contemplate.

The Roads and Traffic Authority of NSW forged an alliance: the LHD Alliance between RTA, Barclay Mowlem Construction Limited, Maunsell Australia and Coffey Geosciences to undertake the project. Its completion earlier than planned is testament to the unique combination of skills that the partners brought to the alliance.

The speakers will present their particular perspectives on the project. Together they will cover the main phases in achieving the outstanding result that is there for all to see. Without doubt the Sea Cliff Bridge, as it is now known, offers a permanent solution as promised by the Minister. It will serve the local community and be a tourist attraction far into the future. This Evening Meeting will be of interest and value to infrastructure planners, consulting engineers, construction contractors and concrete technologists.
