A10 Tauern: four lanes return in the Brentenberg Tunnel
ASFINAG has confirmed that from Saturday morning the Brentenberg Tunnel on the A10 Tauern motorway will once again be open with four traffic lanes. This means the restoration of two lanes in each direction, including towards Salzburg, where severe restrictions had been in place following a truck fire.
The incident occurred on Friday evening, 9 January, when a truck caught fire at the entrance to the tunnel. Immediately after the accident, ASFINAG began assessing the damage and carrying out safety measures. As confirmed after structural tests and analyses of concrete core samples, the tunnel vault is stable. Additional reinforcement will be required only in the area of the gallery preceding the tunnel, where a supporting structure will be installed, enabling the safe restoration of traffic on two lanes in each carriageway.
To enhance safety, the tunnel vault has been secured with protective netting, and further cleaning and technical works are ongoing inside the tunnel, including work on electrical installations, cabling and monitoring systems. The facility will be monitored around the clock.
ASFINAG is also analysing whether a speed limit of 80 km/h or 60 km/h will apply in the tunnel after reopening.
The A10 Tauern motorway is one of the most important Alpine transit corridors, particularly crucial for heavy goods traffic between Germany, Austria and southern Europe. Restoring full capacity ahead of increased seasonal traffic is of key importance for hauliers.
The final repair of an approximately 100-metre section of the tunnel will be carried out in parallel with the planned modernisation of the above-ground section of the A10 tunnel chain, which is scheduled to start in February. Most of the works are to be carried out at night in order to minimise traffic disruption.
