Now onward to replacing the roads and bridges on freeways and highways with these new concrete.
cobblestones for the roads
for slow neighborhood roads I see no reason why brick isn't used more often. my hometown had brick roads everywhere and once every 3-5 years a few bricks would get replaced here and there. in the 1990s I'd look around and see a lot of the bricks on those roads that were made in the 1930s, and there were probably older bricks to be found if I'd looked harder.
the rough ride kept speeding down a lot more than the police could, because I watched people scream through my neighborhood all the time after they paved over the bricks.
plowing snow is harder on brick roads, but it isn't so hard that it is an unsolvable problem.
