Lansing Community College in Lansing, Michigan, is presenting a three-day workshop on March 8, 9 and 10, 2010, to introduce a wide variety of interested personnel, including State Historic Preservation officers, Department of Transportation officials, engineers, engineering students, general contractors, and historic bridge preservationists, to restoration processes of historic metals using electric arc welding, heat straightening, and hot riveting processes. Funded in part by a grant from the National Center for Preservation Technology and Training.

The stiffening effect of existing features on historic truss bridges was examined. 3D analytical models as traditional skeleton structures were compared to models that included the bridge decks.
