The Challenge

Traffic volumes along the Logan Motorway and Gateway Extension have doubled with an eight fold increase in commercial vehicles since 2002. This growth has resulted in increasing congestion at key interchanges and with pressure set to continue with South East Queensland’s population growth. The Logan Enhancement Project aims to address these issues.

Approach and Outcomes

WMS were engaged as contractors to Aurecon to assist with reference design for the new bridge structures and their associated approach embankments for crossings of Slacks, Bulimba, Scrubby and Oxley Creeks. Modelling was undertaken using XP-RAFTS and TUFLOW.
