Savannah&#039;s long-delayed highway project, the Truman Parkway, is one of many large public works projects directed by the Chatham County management of Russ Abolt, County Manager, and Pat Monahan, Assistant County Manager.  The pair has been at the top of county administration for about a quarter century.  Now, Monahan is retiring and Abolt plans to follow suit.  At the same time, four new commission members, including a new chairman, have been elected to set public policy.  (photo Orlando Montoya)
