"In America, we have a ticking time bomb of unfunded liability for infrastructure maintenance. The American Society of Civil Engineers (ASCE) estimates the cost at $5 trillion — but that's just for major infrastructure, not the minor streets, curbs, walks, and pipes that serve our homes."
Now, if we wanted to target a high-need part of infrastructure, we could accomplish a lot with a large sum concentrated on one aspect:
"A recent estimate for the nation’s backlog of bridge repair needs is $125 billion."
To discourage a recurrence of this can-kicking problem in the future, simply require that any state, town, etc. receiving funds for infrastructure has to document their maintenance liability as part of their budgeting. At least that would make the debt more transparent.
Sadly, that doesn't look like part of the plan.
