Historic bridges are a passion for Dr. Abba G. Lichtenstein, so much so that he has spent his professional life working for their salvation and rehabilitation. Although a fighter for bridge preservation, he is an engineer who knows his boundaries. He believes the tendency of bridge owners is to replace a bridge because it is less work for them. However, he points out, it can be more economical to rehabilitate. Two of Lichtenstein's most notable restoration and preservation efforts involved bridges that were influenced by John A. Roebling. His restoration of the cables and piers of the renowned Roebling Aqueduct Suspension Bridge crossing the Delaware River near Lackawaxen, Pennsylvania, received much acclaim. The Roebling Company upgraded a 1903 suspension bridge that spanned the Delaware River between Kellum, New York, and Stalker, Pennsylvania; Lichtenstein again spearheaded the restoration. Among the metal truss bridge restoration projects with which he has been involved, the Nishanic Station, New Jersey, lenticular truss, which is similar to that of Roebling's Smithfield Street Bridge in Pittsburgh, Pennsylvania, is a standout. In addition to having evaluated and designed the restoration and rehabilitation of hundreds of bridges in many states over the years, Lichtenstein's recent experiences with historic bridges include involvement in a statewide study of county bridges in Kansas; preparation of a preservation plan for historic bridges in Maryland; an Indiana program for bridge evaluation in three counties; and evaluation and preservation projects focusing on historic bridges in New York, Virginia, Maine, Kentucky, and other states. In Maryland, his evaluation and preservation design of historic structures of the Chesapeake and Ohio Canal included the Monocacy Aqueduct.
