Heavy duty unsealed roads: upgrading for logging development

The Tarndale Road is a remote road, some 28 kilometres long, situated approximately 80 kilometres Northwest of Gisborne. The area poses significant challenges in road construction activities. The last 10 kilometre section of Tarndale Road forms part of the public road network that enables transportation of logs from two major forests. Over the next 25 years, it is expected that 1.6 million tonnes will be transported from these forests along this road. Tarndale Road was assessed as a high priority within the Regional Development Roading programme funding allocation framework. The design and construct project is being managed by the Gisborne District Council and undertaken by Works Infrastructure. This paper reports on the key drivers that dictated the approach to the road upgrade and the process adopted as a stimulus to these drivers for the investigation, design and construction of upgrade of the existing 10-km road.
