Accessibility and a steady increase in ridership place new demands on the infrastructure of the city railway station Dortmund. Conversion and extension of the light rail system provide the sustainability safely.
The double-lane road tunnel is the centrepiece of the Völkermarkt bypass. The town centre is relieved from heavy traffic which in turn means a better quality of life for the population.
During extension of the Pyhrn motorway, the Gleinalm Tunnel is provided with a second tube. This makes the motorway safer, since there will be no oncoming traffic in the tunnel.
