Extensive Renovation and Safety Upgrade of the Landeck Tunnel
On 1 October 2025, work officially begins on improving traffic safety in the Landeck Tunnel on the Inntal motorway. ASFINAG is building a 7 km long escape and rescue tunnel there, extensively refurbishing the timeworn Landeck Tunnel and reducing the escape route distance in the tunnel to less than 300 m, as required by law.
As part of the work, all operational and safety-related systems, such as the power supply, tunnel lighting, ventilation and fire alarm technology, will be renewed. In addition, the drainage facilities will be adapted and the carriageway and ventilation system will be refurbished. The first construction work began on 22 September in preparation for these measures; tunnelling work will commence in November 2025.

The comprehensive measures will be carried out over the coming years and are expected to be completed by the end of 2030. ASFINAG is currently endeavouring to reduce the necessary closures in the years 2026–2030 to an absolute minimum. For this reason, important consultations with transport planners, but above all with representatives of the municipalities, authorities, chambers of commerce and tourism experts, will continue until the end of the year. The final steps for the necessary closures will then be taken as part of these discussions.
Vibration Control and Noise Level Monitoring During Tunnelling
In order to minimise the impact on the population, an expert report on blasting, vibration and noise emissions was prepared in advance. During the construction phase, vibration control will be carried out during tunnelling and a monitoring system has been set up for noise in order to comply with all prescribed limits.
Very strict guidelines regarding noise and vibration levels apply to night-time operations, as work is carried out around the clock to keep the overall disruption to a minimum. A public information event, also covering the final traffic concept, is planned for early 2026.
Alliance Contract with Östu-Stettin and Spie Dürr Austria
The contract for this comprehensive work has been awarded awarded to the bidding consortium of Östu-Stettin Hoch- und Tiefbau GmbH and Spie Dürr Austria GmbH. The contract is worth more than 226 million euros and will be handled as an ASFINAG alliance agreement. Fifty percent of these investments will go towards the construction of escape and rescue routes and fifty percent towards the general renovation, including all new operating and safety technology. This includes, for example, lighting, ventilation, fire monitoring, fire extinguishing systems, traffic lights, escape route signage, video surveillance, all sensor technology and power supply.
The basic idea behind the concept of an alliance contract is to focus the interests of the contracting parties on the joint success of the project, according to the principle of ‘best for project’. This is essentially achieved through a shared risk philosophy, in which the majority of risks are borne jointly, and a remuneration model in which both contracting parties participate in the success of the project.
