According to BOSIO, the route runs along the left side of the Piave river, along Falzè di Piave, Moriago, Mosnigo and Valdobbiadene (the old Dulpavilis and mansio Ad Cerasias mentioned in the Itinerarium Antonini). From here through Segusino, Vas, Scalon, Caorera and Marsiai, the road reaches Villapiana, passes on the right side of the Piave river at Busche, to reach Cesiomaggiore and Feltre.

OSADA's recent hypothesis identifies the first stretch of the via Claudia Augusta in the straight stretch Altino-Quarto d'Altino, Treviso and Montebelluna, on the basis of topographic (Quarto d'Altino = ad quartum lapidem, Postioma = located at the crossroads with the Postuma route) and centurial confirmations (the stretch Treviso-Montebelluna = the westernmost kardo of the Treviso province).

From Montebelluna, the route reaches Levada, then Fener to meet a road coming from Oderzo. According to the author, the milestone at Fener which has always been linked to the via Aurelia extension (Padova, Asolo, Feltre), should be referred to the stretch Fener-Feltre, taking the via Claudia Augusta as reference.
Finally, from Feltre the via Claudia Augusta leads to Arten, Castel Tesino, Borgo Valsugana, Levico, Tenna and Trento, then from Merano passing by the Venosta valley through the Resia pass (at that time northern border of the Roman Empire) to the Danube plains.

ecent surveys make it clear that the only route named after Claudio was the one crossing the X Regio from the Adige up beyond the Alps through the Resia pass, leading to new routes or intersecting old roads in a close network where Altino, Feltre and Trento are main junctions. Claudio's work allowed a definite consolidation of the link between the Po plains and the Danube area.
