NZ Transport Agency says when the Waikato Expressway is finished it will save 35 minutes on the journey between Tirau and Auckland. My question is where in Auckland do they measure the journey to? Brent Jones, Auckland.
Historically distances between towns or cities were taken from post office to post office. With the closure of many of these in the late 1980s, the measurement becomes problematic.
The Waikato Expressway is another matter. NZTA says it's an overall figure, rather than point-to-point. The stated 35-minute time-saving is over the entire length of the expressway.
So road users travelling from, say, Taupo to Auckland or Tirau to Auckland, in your case, would shave 35 minutes off their total travel time by using the Waikato Expressway once it is complete. There is no Auckland landmark in the equation. The Waikato Expressway will simply create a shorter drive time between destinations by shortening the route and reducing congestion, allowing higher speeds.
