Ariminum became a place of considerable traffic owing to the construction of the Via Aemilia (187 B.C.) and the Via Popilia (132 B.C.), and is frequently mentioned by ancient authors.
1 Augustus's grandson Gaius Caesar had all the streets of Ariminum paved.
From south to north it is traversed by the channel of the Parma, crossed here by three bridges; and from east to west runs the line of the Via Aemilia, by which ancient Parma was connected on the one hand with Ariminum (Rimini), and on the other with Placentia (Piacenza).
It was connected with Ariminum, 33 miles to the south by the coast road, the Via Popillia, which ran on north to Hatria, and joined the road between Patavium and Altinum at Ad Portum.
