Emperor Claudius then restored and widened a Carthaginian trail and extended it west and east.
This way the Romans created a continuous coastal highway stretching for 2,100 miles from the Atlantic to the Nile.
Claudius' road that began west of Carthage followed the coastline connecting the coastal towns.
From Hippo Regius, on the coast, it continued westwards to Icosium (Algiers), Caesarea (Cherchell), as far as Rusaddir (Melilla) and Tingis (Tangier).
It then continued along the Atlantic coast through Iulia Constantia Zilil (Asilah) and Lixus (Larache) to Sala Colonia (near Rabat).
