Road Deconstruction

Whenever I drive through road construction I often muse on the contrast between road construction and road deconstruction. During the deconstruction the road crew seems to work with great speed and vigor; one might even say with gusto. This rapid pace may mislead some into thinking that the construction won't take long. After the initial work of removing the old road has finished, tired perhaps from the laborious feat they have just accomplished, the work crew seem to almost leisurely go about rebuilding the road. I am likely being unfair in my judgment. The work of road construction requires more skill and has many more building regulations than the removal of an old road. What if there is an deeper more psychological reason? The work crew knows that one day their new road will be worn down and damaged by use. When that time comes their work will be destroyed. This thought may cause them to work more slowly to try and protect the road from the inevitable "wear and tear" of motorists. Or maybe they just enjoy ripping up the road more than putting it down. They, like a child that has fun making a mess reluctantly cleans up when told. They even put up signs of protest, "end road work".
