Best terminal location (proposed)
The former Union Station site downtown. Columbus's original Union Station stood where the convention center now rises - the rail approaches are still traceable and the Arena District around it already mixes offices, housing, and entertainment. A terminal here plugs into COTA's bus network and the densest job cluster in Ohio.
