Scott says:

A close look should be taken at the efficiency of road construction projects.
e.g. - The project at 106th So. and State which ended last year had that intersection under construction from ~Oct/Nov 2006 through ~Feb/Mar of 2008! I drive through there every day on my way to/from work. Some areas of the road sat coned off, empty, with no holes or construction going on for several weeks at a stretch. Anyone with minimal project management skills should be able to dramatically improve this situation. I am afraid this is typical for many construction projects and the cost is immense.
