What Roman road, started in 312 BCE, was the first major Roman road?

The Roman road started in 312 BCE and regarded as the first major Roman road was the Appian Way, or Via Appia.

The censor Appius Claudius Caecus began the road during the Second Samnite War. Rome needed a dependable military route into southern Italy, so the new road was designed to move troops and supplies quickly beyond the immediate area of the city. Its first section ran from Rome toward Capua, and later extensions carried it through Beneventum and onward to Brundisium, modern Brindisi.

Roman engineers built the road with layered foundations of stone, gravel, and mortar, topped by tightly fitted paving blocks. Drainage ditches and a slightly raised center helped protect the surface from rain. The route crossed challenging landscapes, including the Pontine Marshes, where a long causeway and bridges were required.

The Appian Way is sometimes confused with the Via Flaminia or Via Egnatia, but those roads were built later or served different corridors. The Appian Way became famous as the “queen of roads” and remained strategically important for centuries. Sections of the ancient route survive today, especially in Rome’s Appian Way Regional Park.
