Among the very most famous Roman roads is the Via Aemilia (now Via Emilia), a straight-as-an-arrow road running diagonally along the edge of the mountains in Northern Italy, and connecting a string of now-famous towns: Rimini, Cesena, Forli, Imola, Bologna, Modena, Reggio Emilia, Parma, Fidenza, Piacenza. You can still bike the whole road: it's SS 9. The "Italy" subway style map completely butchered it. For half of it, they put all the towns on an east-west line, then bent the remainder north to Piacenza. What the...? This isn't some little Roman Road: it's one of probably the top three in the world. And it's a straight line visible from space.
