During a highway project widening in New Haven, Indiana in 1991, a section of the Wabash and Erie Canal was uncovered. Excavation revealed a portion of Lock #2, known as Gronauer Lock. The lock was named in honor of Joseph Gronauer, the lock keeper there for many years. Originally part of a 458 mile canal system that linked the interior of Indiana through Ohio to the Great Lakes, Lock #2 is one of only a few lock structures to that survived to the present. SCIAA contracted with the state of Indiana to conserve the lock at the conservation facility on the University of South Carolina Columbia campus. The recording and numbering of the structural elements of the lock for disassembly and eventual reassembly was accomplished under the supervision of the Maritime Research Division and the Office of the SC State Archaeologist. Now conserved, the lock resides as a main exhibit in the Indiana State Museum in Indianapolis.
