Bodd
Nicely put Bodd, but I'm not sure about #4, and I'd say #5 is down to cheap road design in the first place.
4 & 5 If they encouraged highly skilled management to replace some of the Tongs we have then that would be a start. Instead they will chuck numbers at the problem.
Its alway the problem chuck Numbers rather than lets think about how we invest our money.
