Part-built tunnel near Levkovtsi, on the proposed Pan-European Corridor VIII route between Kumanovo, north of Skopje in North Macedonia, and Gueshevo in Bulgaria. This is on the Beljakovce – Kriva Palanka section, about half-way along the route. This construction work was done between 1994 and 2004 when finance ran out, but there are plans to restart work and finance is reportedly available.
