Waioru Interchange

The AUD$62 million Waiouru Interchange project represents a significant link in Auckland’s transport network. Manukau City Council and Transit New Zealand commissioned GHD as design consultant and then construction contract administrator on the project.

Key features of the project include two grade separated interchanges, the widening of more than two kilometres of motorway, the construction of local arterial roading as well as a large roundabout and a 200-metre long bridge. This challenging project required carefulcoordination to avoid interference with an adjacent power station cooling pond.

Transportation

Economic and population growth, greater urbanisation and increased mobility are boosting demand for new infrastructure and straining the capacity and effectiveness of existing infrastructure. Single mode approaches are no longer viable as governments and stakeholders recognise the need for multi-modal solutions across the whole supply chain.

Across the whole transport spectrum of aviation, marine, roads and highways, rail and transportation and logistics, our team provides integrated transport services throughout the project lifecycle from initial policy, transport economics and business case advice, through concept, procurement, detailed design and construction to operations, maintenance and asset management.
