Construction Date


Wick drains, Geotextile

General Information
Due to increases in population growth throughout Brisbane and most particularly in developing southern and northern suburbs, with the subsequent increase in vehicle movements, the major North South Freeway connecting these suburbs to Brisbane was rapidly becoming traffic choked.

The Gateway Motorway crosses the Brisbane River and additional to major widening and extension of the motorway there was a requirement for the duplication of the existing Gateway Bridge.

The new road alignment traversed very low load bearing soils and required extensive ground treatments which included the use of Global Synthetics high strength geotextile and Global Synthetics wick drains to accelerate the construction processes.
