Zenica tunnel’s left pipe fully drilled on the Corridor Vc in BiH

Workers of the Sarajevo-based company “Euro-Asfalt” broke yesterday the left pipe of the “Zenica” tunnel on the Ponirak Vraca subsection, part of the Vc Corridor.

The left pipe is only five meters shorter than the right pipe, said Ahmed Mušija, head of this project on behalf of the public company “Motorways of the Federation of Bosnia and Herzegovina” for FENA.

The first, right pipe of this tunnel near Zenica, in the length of 3,360 meters, was drilled on November 4.

“The left pipe was drilled at a depth of 530 meters below the surface, i.e. under the Vepar mountain,” stated Mušija.

He points out that about 630,000 cubic meters of rock mass and ground were excavated, and the works were accompanied by problems due to the breakthrough of large amounts of water.

The “Zenica” tunnel passes under the Vepar mountain and will have nine passages for pedestrians, two passages for motor vehicles and two stop niches. The tunnel is being built according to the NATM model (New Austrian Tunnel Method). As much as 14.5 percent of the Corridor Vc route through BiH consists of tunnels.

The value of the works for the construction of the Ponirak – Vraca subsection is EUR 59 million without VAT, of which EUR 50 million are funds provided through the European Investment Bank (EIB) and EUR 19 million are grants from the European Union (EU), which are provided under the Connectivity Agenda through the Western Balkans Investment Framework (WBIF).
