Italian motorway operator CAV announced that the A57 stretch between the Mirano-Dolo junction and the A27 interchange would be completely closed from 21:00 on 12 December until 05:30 on 13 December for urgent bridge maintenance. A secondary closure of the A27/A57 link towards Milan followed from 07:00 to 14:00 on 13 December.
The Mestre bypass forms the main freight artery from the Port of Venice to the A4 east-west corridor. Forwarders servicing fashion and automotive clients in the Veneto industrial belt faced overnight detours of up to 40 km via the SS13 ‘Terraglio’ trunk road, adding 30–45 minutes and minor tolls. CAV advised HGV operators to pre-register convoys larger than 44 tonnes so that escort services could be redeployed.
Passenger traffic also felt the squeeze. Airport shuttles between Venice Marco Polo and Padua diverted through Mirano, while FlixBus rerouted late-evening services to Trieste and Ljubljana. Companies shuttling assignees to the Marghera petrochemical zone were urged to schedule departures either before 20:30 or after 06:00.

For international drivers, technicians and assignees suddenly facing detours or last-minute route changes, ensuring travel documents remain valid is just as critical as mapping alternative roads. VisaHQ’s Italy portal (https://www.visahq.com/italy/) can quickly check visa requirements, secure urgent extensions or arrange multiple-entry permits for non-EU crew members, streamlining compliance while operators focus on logistics.
The episode underscores the fragility of Italy’s ageing motorway viaducts—a legacy risk brought into focus by the 2018 Genoa bridge collapse. Mobility managers should subscribe to Infoviaggiando’s push alerts and build alternative-route maps into emergency-response plans, particularly for critical year-end shipments and relocations.
CAV said the works finished on time and no further closures are expected before January, but a full structural overhaul is planned for Q2 2026, likely requiring longer blockades.
