Yes I heard that fairytale excuse many times before. This excuse is universal and used in other countries as well. Always blame the climate. There are roads in Edmonton that haven’t been resurfaced for 30+ years. The potholes patching is anecdotal. Even when it’s resurfaced, the quality of asphalt is crappy because it’s the cheapest one.
You see a huge difference when you cross the border between AB and BC. Roads in Finland, Sweden are perfect even in colder climate zones as ours. Regular maintenance is the key.
