AEMILIA VIA or AEMILIAN WAY. (I) A high road of Italy, constructed in 187 B.C. by the consul M. Aemilius Lepidus, whence its name ; it ran from Ariminum to Placentia, a distance of 176m. almost straight N.W., with the plain of the Po (Padus) on the right, and the Apennines on the left. The 79th milestone from Ariminum found in the bed of the Rhenus at Bononia records the restoration of the road by Augustus from Ariminum to the river Trebia in 2 B.C. The bridge by which it crossed the Sillaro was restored by Trajan in A.D. Ioo. The modern high road follows the ancient line, and has some original and some fine modern bridges. After Augustus, the road gave its name to the eighth region of Italy.
