The Legacy Way project comprises twin, two-lane tunnels, approximately 4.6kms in length, running straight through between Toowong and Kelvin Grove. Legacy Way (formerly Northern Link) is the fourth project in Brisbane City Council's TransApex plan, designed to reduce congestion and increase connectivity on Brisbane's road network.

Bauer Foundations Australia was awarded the piling works for the Eastern Cut & Cover Structure. The eastern buried structure was constructed as a serious of anchored secant pile walls. A ‘hard-firm’ wall configuration was adopted. Constructing piles in this configuration forms a continuous, near watertight wall, which provides the structural requirements and prevents water or soils leaching between the piles after excavation. The majority of piling works on Legacy Way were secant piles.
