Via Agrippa - The Southern Route

The Southern Route

An ancient salt road passed to the mouths of the Rhône, keeping to the lower slopes of the hills to avoid the river's sometimes swampy flood plain. Under the impetus of Augustus, Agrippa paved a route that lay closer to the river, passing through the important Roman cities of Arles, Avignon, Montélimar, Valence, Vienne, interspersed with relay stations (mutationes) where a change of horses was maintained for official couriers. This route was augmented by the Via Antonina along the right bank of the Rhône.
