Geotechnical investigations are starting next week for the design of a replacement bridge over the Waihou River at Kopu in New Zealand. The bridge forms part of a primary link between Auckland and the Coromandel. Beca Infrastructure is carrying out the design, which expected to take about two years to complete. Client for the work is Transit New Zealand. The new crossing will be 500m long with two lanes and will be built slightly upsteam of the existing bridge. Replacement of the Kirikiri Stream Bridge will also be investigated as part of the project.
