It is the fourth longest tunnel in Croatia, but first in Europe by overburden of 1,336.5 metres (4,385 ft) (height from tube to the ground) in Karst massif.

[2] Not far from the tunnel in the area of Turija, during Napoleon's reign in 1809, a commemorative plaque was placed on the occasion of the completion of the construction of the road that stretched from Obrovac to Boka Kotorska, the so-called French Road.

Two hundred years later, the tunnel was built as part of the modern road links between the Dalmatian hinterland and the coast.

The highest altitude of 1,635 metres (5,364 ft) is approximately halfway through the tunnel.
