Ō Mahurangi – Penlink
Seven kilometres. Five bridges. Massive improvement for Whangaparāoa residents.
Problems with travel to Whangaparāoa were identified as far back as the 1980s. Now, with the development of Ō Mahurangi – Penlink (short for Peninsula Link), and with massive growth expected for the Rodney District, these problems are being addressed.
Our role as a part of this alliance is to construct the 7 km greenfield road, running from SH1 at Redvale to Stillwater and Whangaparāoa. The route has been designed to reduce traffic congestion on Whangaparāoa Road, and provide safer conditions for road users as well as pedestrians and cyclists. HEB will construct the bridges and underpasses, earthworks, ground improvements and pavement.
Construction of the first-in-New Zealand Wēiti River Bridge, a 530-metre extradosed bridge.
1 million cubic metres of earthworks and ground improvements.
Construction of cross culverts, retaining walls, road pavement and shared user path.
Landscaping and offset mitigation planting.
Construction of four other bridge overpasses.
Ecological works are a significant part of the Penlink project, given the scale of the new works and the amount of land and water impacted. During preconstruction, HEB crews are taking great care to clear and rehome lizard, bird and fish species to ensure their protection. As a part of construction and post-construction, we will be restoring vegetated areas and enhancing natural habitats to help the natural world and the new road and bridges coexist.
