A per-mile highway toll? It's being studied for the Bay Area.

[SWBTATTReg]

18. Not that I'm knocking your article, but in most states, don't they already have admin. boards

to admin. bonds, other state-related financial instruments, bank accounts, etc.?

-employees already maintaining roads, other related infrastructure, etc.,

-contracts let out for perhaps for some out-of-the-way or locations located in the least desirable portion of state highways (if there's not a town nearby), as well as towing services (if needed) at these locations too. But usually supply and demand arises to the challenge, that is, if 50 cars/trucks need help every week or so, then a business will probably end up opening to capture that business.

-Cameras? Depends on the location I guess, a lot of inner cities have them, to highlight trouble spots so the state can send the appropriate transportation vehicles to resolve any spotted issues.

-and this is usually all paid for by higher gasoline taxes for the most part...

And a bonus, I guess, is that the highways under toll are supposed in better shape.

Just my 2 cents' worth.
