The bridge crossed the Buthier about 600 m from the eastern exit of the Roman colony Augusta Praetoria; in later times the torrente changed its course, leaving the ancient bridge today without water.[1] The single-arch bridge has a span of 17.1 m and a width of 5.9 m.[1] The arch vault consists of large voussoirs and shows a comparatively flat profile (span to rise ratio 3:1).[2] The facing was built of pudding stone, the spandrels filled with Roman concrete.[1] The structure is dated to the second half of the reign of Augustus (30 BC–14 AD), who had earlier founded the military colony Augusta Praetoria at an important road junction (24 BC).[1] The Pont de Pierre was of particularly strategic importance, since in Aosta the transalpine routes to Gaul branched off into the Little St Bernard and the Great St Bernard Pass.[1] In southeasterly direction towards the Po Valley, the road led over another segmental arch bridge, the excellently preserved Pont-Saint-Martin Bridge, located at the exit of the Aosta valley.
