The objective of this study is to verify the hypothesis “that there is a kind of infrastructure design that people never gets tired of”. In order to examine such a kind of design, a general survey on its images were carried out to show the differences between products and civil infrastructures. Similar sensitivities of the evaluation resulting from a factor analysis are selected and it was shown that, in civil engineering structures, boredom, with progress of time, is classified in the same evaluation axis as in the harmonized cases. Applying the factor analysis results to an arch bridge, a tendency was similar to that of a girder bridge was confirmed. Through the Quantification Theory one analysis it was shown that there is an item / category that is common to different subjects when design that people never gets tired of is performed.
