Pan-European corridors

The Corridor X is one of the pan-European corridors. It runs between Salzburg in Austria and Thessaloniki in Greece. The corridor passes through Austria, Slovenia, Croatia, Serbia, North Macedonia, and Greece. It has four branches: Xa, Xb, Xc, and Xd.

The European Bank for Reconstruction and Development has given loans to support infrastructure improvements along Corridor X.[1]


X: Salzburg - Ljubljana - Zagreb - Belgrade - Ni? - Skopje - Veles - Thessaloniki.

Branch A (Corridor Xa)

Corridor Xa runs between Graz, Austria and Zagreb, Croatia through Croatia, Slovenia, and Austria.

Branch C (Corridor Xc)

Corridor Xc follows the route Ni? - Sofia - Plovdiv - Edirne - Istanbul.

The road in Serbia from Ni? to the Bulgarian border nearby Dimitrovgrad is recently upgraded to a motorway standard. The construction works in all sections are completed on November 9th, 2019 [2].

In Bulgaria, I-8 road connect Sofia with the Serbian border, but Kalotina motorway is planned to supersede it. Currently the transit traffic has to pass via the Sofia Ring Road, but a new bypass Northern Speed Tangent is under construction since 2015[3] and is expected to be completed in 2016. Trakia motorway (A1) runs from Sofia to Chirpan, where Maritsa motorway (A4), completed in October 2015,[4] branches off to Turkey.

In Turkey, Otoyol 3 motorway runs from Edirne to Istanbul.
