I can't help but look at the roads and sidewalks and think there's a solution that could be implemented there. I'm no engineer, but I expect that you could install something along the fault line that allows the road to slide apart without disruption. It seems like a waste to just keep repaving the same spot over and over, just for it to crack again.
Maybe tear up a couple feet of pavement and put in two metal grates that can slide past each other. That should at least buy you a decent amount of time, until the road is so warped that the lanes don't line up.
This was one of my thoughts as well; as a software developer I'm always trying to figure out solutions to problems but I know just about nothing when it comes to civil engineering. So naturally I keep coming up with crazy ideas to prevent / fix this and none of them are probably feasible :)
But it's certainly interesting to review stuff on the internet about how structures can avoid these issues.
