Inscription.
La viabilità principale della città era costituita dal Decumano e dal Cardine, che si incrociavano in corrispondenza del Foro. Il primo era il tratto urbano della Via Ostiense che, correndo in direzione est-ovest, si dirigeva verso il mare piegando leggermente a sud. Il Cardine corrispondeva nel tratto meridionale al tracciato urbano della più antica Via Laurentina; il tratto settentrionale, creato ex novo, raggiungeva la sponda del Tevere. Si dirigevano verso il fiume anche altri percorsi, come Via della Foce e la Semita (o sentiero) dei Cippi, importanti a scopi commerciali. Molti dei più importanti assi viari cittadini si impostavano su più antichi percorsi, a cui si deve l'irregolarità negli orientamenti dei diversi quartieri. Esisteva inoltre una fitta rete di vie secondarie.
The city's main streets were the Decumanus and the Cardo, which crossed each other at the Forum. The former was the stretch of the Via Ostiensis inside the city, running east-west and turning slightly towards the south in the direction of the sea. The southern stretch of the Cardo followed the course of the more ancient Via Laurentina inside the city; the northern stretch, built from scratch, reached the banks of the Tiber. Other streets also ran towards the river, like Via della Foce and the Semita (or path) dei Cippi, important for commercial purposes. Many of the city's major streets were built over more ancient routes, thus explaining the irregular orientation of the various districts. There was also a dense network of smaller lanes.

Excerpt: "The Decumanus Maximus is the main street in the east half of Ostia. It runs from east to west, starting at the Roman Gate. At the west end is the Crossroads of the Castrum, where the road branches in two directions. One branch (also called Decumanus Maximus by the excavators) leads to the Marine Gate, to the south-west. The other branch (Via della Foce) leads to the north-west, to the Tiber mouth."(Submitted on August 8, 2025, by Sean P. Flynn of Oak Park, Illinois.)
