Unfortunately road maintenance seems to be a very low priority in the UK and with council budgets being cut over the last few years the roads departments are getting less money to replace worn out roads and are merely filling holes when they are reported.
there are still some really good roads but they tend to be in more rural areas that don't have the volume of traffic to wear out the surface so quickly.
A lot of damage is being done with the colder winters where roads are falling apart and there is no money to repair them.
The Government would rather spend money on the great unwashed who choose not to work than cater for the majority who contribute to society. Rant over meantime.
