Together with the neighboring Nasenbachtalbrücke and the border bridge over the Schönwalder Bach , it forms the German part of the border section to the Czech Republic on federal motorway 17.
The tunnel is 300 m long and stretches from 43.950 to 44.250 kilometers of the A 17 and is thus about 2.5 km south of the former common border crossing point Breitenau / Krásný Les (Schönwald), as this is not on the immediate border. The border crossing point was dismantled in 2010. The tunnel is about 1 km after the border on the German side. The border line is roughly in the middle of the border bridge over the Schönwalder Bach. The tunnel has a clear height of 4.50 m and a clear width of 13.50 m.
It is one of the three landscape tunnels on the A 17. Like this, the Harthe landscape tunnel was not built by mining and only for ecological reasons. It connects the Harthe, a forest and meadow area that begins near Fürstenwalde , with the corridors of Breitenau and Kleinliebenau .

Construction began in spring 2004 and was completed in October 2006. The tunnel was opened to traffic together with the entire third construction section of the A 17 and the neighboring section of the Czech D 8 motorway on December 21, 2006. The tunnel is the last of construction of the A 17 built on the German side.
The 300 m long landscape tunnel was built using the open tunnel construction method. The two tubes are each 13.6 m wide and have no special technical equipment. The structure cost around 1.2 million euros and was built by the Nasenbachtal consortium, consisting of Porr Germany and Hochtief AG .
purpose
The so-called biotope network will be guaranteed by the structure even after the motorway has been commissioned . This enables a level connection path between the forest and open land areas on the eastern ore mountain ridge . Biotopes These are the A 17 separately so that the types of movements can be performed only at passages and subways and at such buildings. In the case of the landscape Tunnel Harthe to deer , wild boar , other small game as well as other species such as bats and low-flying birds cross the highway.
