The proposed length of the tunnel of over 15 km would place it among the longest road tunnels in the world. The main reason to build a motorway tunnel of such length was to protect the environment in the Kresna Gorge.

The design works of the tunnel began in 2013.[1] The construction was expected to begin in 2016,[2] using the New Austrian Tunnelling method due to the diverse geology in the Kresna gorge, which makes the usage of TBM inapplicable.[3] The construction costs along with the access roads were estimated at 1.1 billion levs (~560 million euro).[4] As of 2015, plans were abandoned and an alternative route east of the gorge is being considered, which will involve a series of shorter tunnels and viaducts.[5]
