This is maybe a tangent but if everything collapses when one road is closed that suggests a system lacking resiliency.

  Typically it’s not one road... it’s a large portion of a city. For instance, in the town I live when a marathon happens I have to drive out of town, then back in, to get to the other side of town.

  True, but you don't need a marathon to tell you that. Just go anywhere downtown at rush hour on a weekday. Every 5 minutes, some driver will enter the box before it's clear, and block the intersection both ways for everybody. A couple months ago, a package truck crashed on the freeway a mile ahead of me, and traffic didn't move for over 3 hours. Our roads are not designed with redundancy as a primary concern.

    Not exactly what you meant, but I believe the interstate highway system was designed for redundancy for military mobility as a primary concern after WWII because of how easily rail could be taken out.

  It's never just one road... they're long distance marathons not foot races.
