paulchinnz: Main artery between Chch airport and city centre also 60 km/h for substantial portion, although frequent roadworks since earthquakes means some segments often actually 30 km/h limit.
Not that anyone obeys those 30km/h limits, which is something that really annoys me. When I follow the limit in one of those temporary roadworks zones people seem to behave as if I'm one of those annoying people who do 80km/h in a 100km/h zone.
