The Brief

The Northern Arterial Road (NAR) provides a link through western Kaiapoi to Rangiora. The project covered a two-kilometre stretch of road with seven intersections, two bridges and two superelevated corners. The NAR forms a vital east–west connection between Kaiapoi and Rangiora and to and from State Highway 1. Its construction was required as part of the Outline Development Plan for the area prior to development within West Kaiapoi. Challenges Identified

What We Did

We provided a range of surveying, planning and engineering services for a new road layout designed to bypass the 1,200-lot Silverstream subdivision and the associated New Arterial Road. The process included completing the survey to stop a portion of Giles Road that was incorporated within the Silverstream development. As some of the internal roads crossed the underlying Giles road, this specific area was not stopped and left as an abuttal. The other portion of road to be closed was an unformed portion that lead to a crossing of the Kaiapoi River.

The NAR roading corridor was legalised under the Resource Management Act by subdivision, with the existing roads closed under the Public Works Act with an associated Survey Office plan.

Throughout the process, we worked closely with the Waimakariri District Council property management team and The Property Group Ltd, who were carrying out the formal process of closing the road under the Public Works Act.

Key Deliverables

We delivered a design that met all relevant guidelines, council codes of practice and district planning requirements.

This NAR project, ensured that existing safety and bridge loading deficiencies could be addressed and provides an improved, safer road network.
