The road that in Roman times led from Aquileia to Tergeste in the section east of Monfalcone ran along the coastline and crossed the Locavaz River on a bridge of which nothing remains visible today.
Alberto Puschi, director of the Trieste Civic Museum from 1884 to 1918, noted some of its elements in 1898. Speaking of the road he wrote that ... vestiges can still be seen across the marsh where it seems to lie on dam... referring to the then swamped area between the Lisert and the mouths of the Timavo River.
From his notes we know that the bridge, made of sandstone and limestone, had two arches.
The inscribed limestone block recovered in 1932 during reclamation work on theLisert marsh seems to be pertinent to it.
Membership LEG XIII mentions the 13th Gemine Legion whose soldiers would have been employed in the construction of the road and bridge or their rearrangement in the second half of the 1st century BC.
