In the first decades of this epoch these were prosecuted on the greatest scale, and the construction of roads in particular had at no time been so energetically pursued.

In Italy the great southern highway of presumably earlier origin, which as a prolongation of the Appian road ran from Rome by way of Capua, Beneventum, and Venusia to the ports of Tarentum and Brundisium, had attached to it a branch-road from Capua to the Sicilian straits, a work of Publius Popillius, consul in 622.
On the east coast, where hitherto only the section from Fanum to Ariminum had been constructed as part of the Flaminian highway (ii.
229), the coast road was prolonged southward as far as Brundisium, northward by way of Atria on the Po as far as Aquileia, and the portion at least from Ariminum to Atria was formed by the Popillius just mentioned in the same year.

The two great Etruscan highways-- the coast or Aurelian road from Rome to Pisa and Luna, which was in course of formation in 631, and the Cassian road leading by way of Sutrium and Clusium to Arretium and Florentia, which seems not to have been constructed before 583--may as Roman public highways belong only to this age.

About Rome itself new projects were not required; but the Mulvian bridge (Ponte Molle), by which the Flaminian road crossed the Tiber not far from Rome, was in 645 reconstructed of stone.

Lastly in Northern Italy, which hitherto had possessed no other artificial road than the Flaminio-Aemilian terminating at Placentia, the great Postumian road was constructed in 606, which led from Genua by way of Dertona, where probably a colony was founded at the same time, and onward by way of Placentia, where it joined the Flaminio-Aemilian road, and of Cremona and Verona to Aquileia, and thus connected the Tyrrhenian and Adriatic seas; to which was added the communication established in 645 by Marcus Aemilius Scaurus between Luna and Genua, which connected the Postumian road directly with Rome.
