“They say all roads lead to Rome—but exactly how many Roman roads were there? According to new research, potentially over 68,000 miles (over 110,000 kilometers) more than previously known.

Meet Itiner-e, a new high-resolution digital dataset and map of the Roman Empire’s roads around 150 CE. A team of researchers used archaeological and historical records, topographic maps, and satellite imagery to create the behemoth, which charts 185,896 miles (299,171 km) of roads across almost 1,544,409 square miles (4,000,000 square km).”
