Roading

​​​​​​Whanganui District Council provides a road network that has an all weather surface with good skid resistance, visibility and smoothness. It is capable of carrying both light and heavy vehicles.

Access to all District properties is provided through 220km of urban roads and 615km of rural roads, including 74 bridges. Traffic management is provided through control systems, signs and markings.

219km (99%) of the urban and 314km (51%) of the rural roads are sealed. 94% of urban sealed roads have kerb and channel both sides. Sealed road roughness is kept below the point that causes high vehicle wear.

Road widths/shape are approximately relative to the vehicle volumes carried. Vegetation mowing/cutting is carried out to specified distances from the road.

Unsealed roads are maintained to the following standards:

  • Potholes - repaired before they reach 50mm depth.

  • Corrugations - repaired before they reach 25mm depth.

  • Grading to standard cross section profiles of 5-7% camber.

Urban roads are swept to keep litter and dust to specified minimum standards.
Safety is maintained by traffic control/calming devices e.g. signs, islands, flush medians, traffic lights, edge markers etc. Most sealed roads more than five metres wide have markings to guide traffic – repainted regularly to maintain clarity.

The Council provides road lighting to promote safe night usage – meaning brighter lighting on busy roads.

Stormwater control is provided, so that roads have limited ponding in all but large storms.

​There are 2.6km of cycle ways on some busy and narrow roads, eight service lanes (0.9km total) to give rear access to commercial properties in the Central City area.

Most road maintenance activity is paid 38% by the ratepayer and 62% by Land Transport New Zealand (central government agency). Other roading activity is paid 28%/72%.
