ANTHONY FALLS (I-35W) BRIDGEMinneapolis, MinnesotaFIFTH STREET PEDESTRIAN PLAZA BRIDGEAtlanta, GeorgiaDEVIL’S SLIDE BRIDGEPacifica, CaliforniaDAGGETT ROAD BRIDGEStockton, CaliforniaWINTER 2008Dr. Ahlborn’sPerspective on Sustainabilitycorrectly champions the role of education in therealization of a sustainable future. Innovativesolutions are definitely needed; however,none of the three “tenets” of sustain-ability(environmental, social and economic) deserverelegation to a diminutive role. Will merelyshifting the focus of engineering educationto social and economic tenets rather thanenvironment issues solve our problems? Anotherquestion concerns whether an economic costbenefitanalysis accurately reflects environmentalvalues. Social and economic well-being of ourspecies, as we know life, depends on a healthy,sustainable environment . . . Engineeringeducation must not restrict itself to the free-bodydiagram boundaries within an engineeringproject. It may not be appropriate to onlyexamine efficiencies of a bridge joint whenwe need to holistically examine the entiretransportation system and its relationship to ourother life-support systems.Roger PatockaEstherville, Iowa[Editor’s Note: Mr. Patocka raises significantissues concerning our standard design practice fortransportation systems and our focus toward theenvironment. Individually, we may not have directcontrol over long-range solutions needed to affectchange for the planet, but we do have choicesin our design solutions and the materials thatwe select on a daily basis that will have positiveimpacts. This is one of the ultimate challenges ofsustainability, changing our design philosophiesto truly think holistically. See the article on page16 that provides another installment in our goalof environmental awareness.]Congratulations on a great inaugural yearand your vision that has been realized. Thisis a great magazine that allows the bridgeprofessional to review the state-of the-art ofconcrete bridges in one publication.
