If that was in the USA, there would be environmental impact studies, worker safety standards, wages standards set, bids sent out, etc. This would take several years. In Peru, the job is accomplished without anyone telling what to do, how to do it, and when to do it. Replacing the bridge each year or so is what is called job security. Wonder what the people do the rest of the time?
Harry, thanks for the video. Hope their government doesn't hear of this and get involved in screwing up a good system.
Life is like water-skiing; if you slow down, you go down.
