Major traffic arteries are simultaneously the most-sensitive-to and in-need-of efforts to improve the methodologies of their purpose.

I was superintendent of construction for such a project in a small community sat astride a regional main thoroughfare. It covers a broader spectrum of experience than one might initially think.

No big problem. The end result will be worth it.
