Via Flaminia

The Via Flaminia was an ancient Roman road leading from Rome over the Apennine Mountains to Ariminum (Rimini) on the coast of the Adriatic Sea, and due to the ruggedness of the mountains was the major option the Romans had for travel between Etruria, Latium and Campania and the Po Valley. Today the same route, still called by the same name for much of its distance, is paralleled or overlain by Strada Statale (SS) 3, also called Strada Regionale (SR) 3 in Lazio and Umbria, and Strada Provinciale (SP) 3 in Marche. It leaves Rome, goes up the Val Tevere ("Valley of the Tiber River"), strikes into the mountains at Castello delle Formiche, ascends to Gualdo Tadino, goes over the divide at Scheggia Pass, 575 m (1,886 ft), to Cagli. From there it descends the eastern slope waterways between the Tuscan-Emilian Apennines and the Umbrian Apennines to Fano on the coast and goes north parallel to Highway A1 to Rimini.

This route, convenient to ancients, is now far from it due to heavy modern traffic between north Italy and the capital. It remains a country road, while the traffic crosses by railway and autostrada through dozens of tunnels between Florence and Bologna, a shorter, more direct route under the ridges and nearly inaccessible passes.

It was constructed by Gaius Flaminius during his censorship (220 BC). Sources mention frequent improvements being made to it during the imperial period. Augustus, when he instituted a general restoration of the roads of Italy, which he assigned for the purpose among various senators, reserved the Flaminia for himself, and rebuilt all the bridges except the Pons Mulvius, by which it crosses the Tiber, 3 kilometres (2 miles) north of Rome (built by Marcus Aemilius Scaurus in 109 BC), and an unknown Pons Minucius. Triumphal arches were erected in his honour on the former bridge and at Ariminum, the latter of which is still preserved. Vespasian constructed a new tunnel through the pass of Intercisa (Furlo), in 77, and Trajan, as inscriptions show, repaired several bridges along the road.
