Recent view of the location of the Donham Avenue Viaduct at Eastern Avenue in Columbia-Tusculum, looking southwest. This single track viaduct connected both the CG&P and two IR&T lines to the East End streetcar line on Eastern Avenue. The viaduct was the only way to cross the then-busy Pennsylvania/Little Miami Railroad which is visible down the street. It was a bad bottleneck, and the woman who lived on the first floor of this house even sued because passengers could look directly into the one first floor window on the side of the house.
