That it takes years to plan means you have time to work with the road people. We will have to dig this road up anyway don't resurface it. Often they know roads were built sub-modern standard and want to dig it up but it isn't ecconomical.

this needs to be done for all roads constantly sometimes the pipes are still good and you resurface, sometimes they will fail in a few years so may as well dig them up since we have to do the road now.
