Al oest del poble de Donnas, a la Vall d'Aosta, hi ha un dels trams més impressionants de la enginyeria viaria romana, En aquest punt, el riu Dora Riparia anava mot arrant d'un cincle de pedra, no deixant espai fisic per ni tansols una via romana. Doncs aquests excavaren un tram sencer en roca viva per tal de fer passar el trafic a una distancia segura del riu, famós per les seves crescudes salvatges.
Els enginyers romans varen excavar a la roca vlva un tall de 221 metres de llargada, buidant en ocasions fins a 12 metres de profunditat desde el relleu natural. Aquest arc (o tunel) de pedra natural fou deixat com a testimoni del nivell d'esforç necessari per a aital obra d'enginyeria. A uns vint metres d'aquest, i formant part de la mateixa roca natural, hi ha un mil·liari de pedra natural amb la única inscripció XXXVI, és a dir trenta-sis milles des de la Colonia Augusta Praetoria Salassorum, l'actual Aosta.
Tot plegat fou excavat cap als anys 31 i 25 a.C., en el periode inicial del Imperi Romà sota August.

Picture taken with a Rolleiflex 3.5F, made c.1969-1971; Carl Zeiss Planar f3.5 / 75mm lens; Kodak Ektar 100, developed with the Bellini C41 kit.
To the west of the village of Donnas, in the Aosta Valley, there is one of the most impressive stretches of Roman road engineering in the World. At this point, the river Dora Riparia ran straight by a stone cliff, leaving no physical space for not even a Roman road. Well, they excavated an entire section in live rock in order to allow traffic to pass at a safe distance from the river, famous for its wild floods.
The Roman engineers excavated a 221 meters long cut through hard rock, digging on occasions up to 12 meters deep from the natural relief. This native stone arch (or tunnel) was left as a testament to the level of effort required for such a work of engineering. About twenty meters away, and forming part of the same natural rock, there is a milestone (miliarium) with the inscription "XXXVI", that is to say thirty-six Roman miles from the Colonia Augusta Praetoria Salassorum, today's Aosta.
Everything was excavated around the years 31 and 25 BC, in the initial period of the Roman Empire under Augustus.
