The Trebersing enclosure on the A10 Tauern Autobahn was extensively renovated and modernized in 2022 and 2023. In September 2022, the technical upgrade of the 850-meter-long enclosure began, including the installation of energy-efficient LED lighting. This measure increased traffic safety and reduced energy consumption.

The work in the direction of Villach was completed by mid-December 2022, while the renovation in the direction of Salzburg began in mid-January 2023 and was completed with successful trial operation at the end of April 2023.
