On Saturday, May 9, 2026, the Federal Roads Office, in collaboration with the Municipalities of Lumino and San Vittore, invites the public to an open day at the environmental compensation site along the A13. The event, which will take place from 9 am to 4 pm, will allow visitors to discover the works carried out between 2024 and 2026 to mitigate the impact of the highway on the territory. Among the most significant interventions are the bypass of Roveredo, the half-interchange of San Vittore, and the correction of the Moesa River.

Educational trail and environmental interventions

For the first time, it will be possible to walk along the new educational trail that starts at the ice rink in San Vittore and ends in Lumino. Along the approximately 7 km route, areas of renaturation have been created in the nationally important riverbanks. These interventions have given space back to the river, raised the water table, and created diverse aquatic environments, riverine forests, and wet meadows, which are fundamental for biodiversity and the hydrological stability of the entire area.

Operational details

Analysis of environmental compensation works

The environmental compensation works carried out along the A13 between Lumino and San Vittore represent a significant example of how infrastructure can be sustainably integrated into the territory. These interventions not only mitigate the impact of road works but also contribute to improving the biodiversity and hydrological stability of the area.

Floodplain renaturation

One of the most important aspects of the project is the renaturation of nationally significant floodplains. These interventions have allowed space to be returned to the river, raising the water table and creating diverse aquatic environments. The presence of floodplain forests and wet meadows is fundamental for biodiversity and the hydrological stability of the entire area. These environments offer ideal habitats for numerous animal and plant species, contributing to maintaining the ecological balance of the area.

Wildlife crossing

The 42-meter-wide wildlife crossing is an innovative element that allows wild animals to safely cross the A13. This intervention is particularly important for reconnecting an ecological corridor that has been interrupted for decades and for reducing the risk of road accidents. The presence of a safe crossing for wildlife not only improves road safety but also contributes to maintaining the ecological connectivity of the territory, allowing animals to move freely between different natural areas.
