The infrastructure in the tunnel systems in the area Flachau on the A10 Tauern motorway has been undergoing extensive modernisation by ECOexperts in a joint venture with Leyrer+ Graf since October. This is to ensure that the tunnel infrastructure will continue to meet the highest safety and efficiency standards for decades to come. This major project, which is scheduled for completion by June 2025, requires precise planning and execution, as the conversion is taking place in parallel with a complex construction project to renovate the anchor wall and while the motorway is still in operation.
As part of the renovation, which has become necessary after more than 20 years of operation, the tunnel’s entire electrical system is being replaced. The project includes the connection to the ASFINAG traffic management centre with the modernised redundant servers and control units. The latest version of RadeRunner is used as the control system. RadeRunner, as a process control system, which is also used at the control level, meets all the requirements of the current NIS directive.
Furthermore the project covers the complete installation of an efficient LED lighting, of a modern emergency call system, a new central fire alarm system, as well as the updating of the uninterruptible power supply (UPS) and an advanced traffic control system.
The project is divided into two phases: the first phase of the renovation of the carriageway will take place from October to November 2024, while the second phase for the opposite carriageway is planned for April to June 2025. During this construction period, the tunnel will be operated in two-way traffic to maintain traffic flow. To ensure safety during the modernisation, the new control units will be installed and tested in parallel with the existing system. This ensures continuous monitoring and control of tunnel operations, even during construction work.
By modernising and refurbishing the technology, ecoexperts is ensuring that the tunnel system on the A10 Tauern motorway meets the
