earlier attempts, but he failed. The causeway and its bridges subsequently needed constant repair. In 162 BC, Marcus Cornelius Cathegus had a canal constructed along the road to relieve the traffic and provide an alternative when the road was being repaired. Romans preferred using the canal. Along the coast The Via Appia picked up the coastal road at Tarracina (Terracina). However, the Romans straightened it somewhat with cuttings, which form cliffs today. From there the road swerved north to Capua, where, for the time being, it ended. Caudine Forks was not far to the north. The itinerary was Aricia (Ariccia), Tres Tabernae, Forum Appii, Tarracina, Fundi (Fondi), Formiae (Formia), Minturnae (Minturno), Suessa, Casilinum and Capua, but some of these were colonies added after the Samnite Wars. The distance was . The original road had no milestones, as they were not yet in use. A few survive from later times, including a first milestone near the porta Appia. Extension to Beneventum The Third Samnite War (298–290 BC) is perhaps misnamed. It was an all-out attempt by all the neighbors of Rome: Italics, Etruscans and Gauls, to check the power of Rome. The Samnites were the leading people of the conspiracy. Rome dealt the northerners a crushing blow at the Battle of Sentinum in Umbria in 295. The Samnites fought on alone. Rome now placed 13 colonies in Campania and Samnium. It must have been during this time that they extended the Via Appia 35 miles beyond Capua past the Caudine forks to a place the Samnites called Maloenton, "passage of the flocks". The itinerary added Calatia, Caudium and Beneventum (not yet called that). Here also ended the Via Latina. Extension to Apulia and Calabria By 290 BC, the sovereignty of the Samnites had ended. The heel of Italy lay open to the Romans. The dates are somewhat uncertain and there is considerable variation in the sources, but during the Third Samnite War the Romans seem to have extended the road to Venusia, where they placed a colony of 20,000 men. After that they were at Tarentum. Roman expansion alarmed Tarentum, the leading city of the Greek presence (Magna Graecia) in southern Italy. They hired the mercenary, King Pyrrhus of Epirus, in neighboring Greece to fight the Romans on their behalf. In 280 BC the Romans suffered a defeat at the hands of Pyrrhus at the Battle of Heraclea on the coast
