[1] Situated between the Via Cassia and the Via Aurelia, it is different from them notably in that the latter was designed primarily for military long-haul, irrespective of settlements they met, but the Via Clodia was of short-range, intended for commercial traffic with the colonies in Etruscan lands.
The existing road was probably used as a way of penetration and conquest of Etruria by the Roman army begun in 310 BC.
The stretch between Bracciano and Oriolo Romano continues a straight line whose paving stones are found here and there, often uprooted.
Its course, for the first 11 miles, was the same as that of the Via Cassia; it then diverged in a northwest direction and ran on the west side of the Lacus Sabatinus, past Forum Clodii and Blera.
[3] The Via Clodia Nova extension was constructed in 183 BC by the consul Marcus Claudius Marcellus.
