|1910||OPR's Maurice O. Eldridge addresses the Second Annual Convention of the Southern Appalachian Good Roads Association in Knoxville, TN, on "Road Laws and Road Building." As a Tennessee native, he recalls his boyhood days when, under the "statute labor" system, citizens paid their road tax by working on the roads. "We used to turn out in the fall of the year, in September or October, when the roads were hard and dry, and pile up clods, sods and vegetable mold in the middle of the road. If there were any mudholes we would usually haul large stones from adjacent fields and fill them, and that would usually make two mudholes, which were filled in the same way the following year."|

"There is but one limit which may reasonably be set. It is this: No road should be improved by expenditures of public funds in excess of its earning capacity. The return to the public in the form of economic transportation is the sole measure and justification of the degree of highway improvement."
|1970||Administrator Frank Turner speaks on "Urban Growth and Mobility in the United States," at the Sixth World Highway Conference in Montreal. He says that deciding the role of each transportation mode is an issue of public policy. "The question is not so much one of choosing between competing modes as it is one of providing an effective mix of complementary modes."|
|1977||In Portland, OR, Administrator William Cox tells the Northwest Bridge Engineers Seminar that highway transportation would predominate over all other transportation modes for the foreseeable future. "Consequently, we have to correct problems with highway bridges immediately." He adds, however, that the size of the bridge program "must be based on a realistic assessment of what can actually be accomplished."|
