OmnesViae.org offers a Google Maps type reconstruction of the Tabula Peutingeriana, a medieval copy of a Roman roadmap from about the year 300 CE.
You can get a real feel for the length of journeys during that period and scale of the Roman road network. A trip from Athenas (Athína) to ROMA (Roma) would require fording eight rivers and traversing three mountain ranges.
All roads did lead to Rome.
