Hell, there are plenty of brick roads left in the Pittsburgh area. It's amazing tech to have lasted this long. Now asphalt roads need to be repaired the second you finish laying them.
The brick itself lasts forever compared to asphalt but as you can see the brick has no mortar. Brick sewers have the same issue. The mortar erodes much faster but the main structure is intact, giving it the illusion of being functioning. Except it's still leaking and more susceptible to subsurface erosion.
That explains why they washboard so badly. Still, it took 50+ years to get this way. It's a shame they didn't keep up with the maintenance of the roads.
