Here it seems like every time you turn around there's new poles replacing the old ones. It's kind of making me mad to see all of the oldies go. What's annoying too is that there's still some poles that have been awaiting to be hooked up since 2017! It's also annoying when they replace poles that are only a few years old or in perfect condition!
Are they wood, concrete or steel poles? With wood poles that frequent change would make sense, as they could be supporting a lot of weight in a hot humid zone, so they rot and weaken faster. Concrete and steel poles can remain untouched for decades and still being strong, so changing them frequently wouldn't make sense, unless the operation conditions are like holding the weight of a car in an ambient like the deep Amazon.
