Gary, the Erie Northshore is owned by the EG&E, but operated as an independent company. My bridge (and that of everyone else who owns a Central Valley truss bridge) has a built date of 1902.
The Pratt truss design was patented in 1844 and used for both wood and steel (iron) bridges. Here's some info (probably more than you'd care to read) on truss bridges.
