A platform for research: civil engineering, architecture and urbanism
Since 1975, when the Historic American Engineering Record (HAER) began a concerted effort to document the historic bridges of the United States, over 250,000 bridges have been scheduled for replacement because they are structurally deficient or functionally obsolete. Without this program the nation stood to lose, in a single generation, the physical evidence of one of America's greatest engineering and manufacturing achievements — the fabricated metal truss bridge. It is not possible to save all historic bridges, but through HAER documentation, selected examples are being preserved on paper, and hopefully, a selection of the truly outstanding bridges can be saved for posterity.
