SH1 Old North Road
This 1 km project on SH1 north of Whangarei involved widening to provide a southbound passing lane and realignment to address the poor safety record.
A flexible approach
The geotechnically active slopes had resulted in longstanding movement in the road and on-going maintenance issues. The section of road had complex geotechnical foundation conditions that required a flexible and proactive approach to adapt the design to accommodate the complexity as it was revealed during the wall construction.
A cultural icon
The project features two panel retaining walls with an Iconic design representing the local short fin eel that was a valued food source of the local iwi and once widespread in the land overlooked by the walls.
