That looks like a good idea however my concern is that they will close the post offices. Similar to banks where people use ATM's so they closed local banks.
I think it is a combination of:-
More cars than planned
A lot of rain
Lack of maintenance..... man power, cost, to much etc
When maintenance is done it is done quickly but not well..... can't close roads to do it properly.
Might be better and quicker if it was contracted out to private people
