The project consists of nearly 1km of acoustic barrier, divided into 3 sections. This comprises of 233, 3m high panels which have varied extrusion depths between 30mm and 60mm, and a concrete fibre cement footing which varies in dimensions to fit the existing narrow corridor. The design and construction of the project lead innovations in stakeholder engagement processes, prototyping using 3D printing and special mould design to replicate the panel design. The panel design is directly influenced by the local Iwi and are symbols of guardianship and protection echoing the benefits of the acoustic barrier. The narrative of the design depicts a waka within a river, represented by the motorway, transporting people such as it was in the past.
