> or if that happens in mostly the same areas There aren't that many canals outside of Amsterdam's center. The ones outside of the center tend to be cleaner as well, because, well, less people around them at all times, and more logically separated from the population (think: parks around them, not houses and bike parking spots right next to the canal). I didn't put a lot of effort in finding the exact location of this excavation, but there are some mentions of Damrak on the site, which is as center Amsterdam as it can get.
