Motorway A1
The A1 Motorway route on Corridor Vc is designed in accordance with TEM standards, with two separate carriageways, each with two traffic lanes (running and transverse) for each direction of movement, and one stopping bar for forcible stop in each carriageway.
On the motorway A1 ere is the Center for Traffic Maintenance and Control in Bosnia and Herzegovina, the most important facility on the A1 motorway, which is used for accommodation of units for maintenance, monitoring and management of traffic on the highway in accordance with the European Commission Directive 2004/54 / EC.
The Svilaj – Odžak section is 10.7 km long and is strategically important not only for improving the road infrastructure, but also for regional cooperation and better communication with the EU.
The construction of this section cost 69.2 million euros including VAT, and the works were financed from credits from the European Investment Bank (EIB) and the European Bank for Reconstruction and Development (EBRD), grant and own funds of JP Autoceste FBiH.
The project was co-financed by the European Union with grants in the amount of 17.4 million euros, which were secured as part of the Connectivity Agenda through the Western Balkans Investment Framework (WBIF).
The works were carried out by Austrian Strabag and BiH companies Euro-asfalt and ŽGP, and the consultant was Aecom Inocsa S.L.U. from Spain.
Significant structures on the section include four overpasses, three underpasses, three wildlife crossings, two interchanges, a rest area, a front toll booth and two bridges.
This part of the motorway on Corridor Vc, the so-called Zenica bypass consists of three subsections, Drivuša – Klopče, Klopče – Donja Gračanica and part of the subsection Donja Gračanica – Zenica Tunnel with a total length of 11 kilometers.
The construction of the Zenica bypass connected Zenica North and Zenica South on the motorway.
The total investment value of the works amounted to 225 million euros, and the funds were secured through international financial institutions (KFAED, EBRD, OPEC) and grants from the European Union, which were secured as part of the Connectivity Agenda through the Western Balkans Investment Framework (WBIF).
The works on the construction of subsections within the Zenica bypass were carried out by prominent domestic and foreign companies.
The works on the Drivuša – Klopče subsection were carried out by the local company Hering d.d. Široki Brijeg, the Klopče – Donja Gračanica subsection was built by a consortium of companies comprising Euro – Asfalt d.d. Sarajevo and Strabag Austria, while the works on the Donja Gračanica – Tunnel Zenica subsection were carried out by the Turkish company Cengiz insaat Sanayi ve Ticaret A.S.
What all subsections within the Zenica Bypass have in common are numerous problems and challenges, mostly caused by extremely poor geological and morphological conditions, and demanding terrain with high complexity of works, which required the construction of many structures on the motorway.
13 structures were built on the subsections, meaning that nearly 50% of the section is covered by structures. The complexity of constructing these subsections is best illustrated by the fact that more than 340,000 m3 of concrete and 37,000 tons of reinforcement were used.
The most challenging structures for the contractors on the Drivuša – Klopče subsection were the Drivuša Bridge and the Perin Han Viaduct, and the relocation of the regional Sarajevo – Zenica gas pipeline was another demanding task alongside the construction of the subsection itself.
On the Klopče – Donja Gračanica subsection, a particular challenge was the construction of the Babina Rijeka Viaduct, with its highest point between the viaduct and the ground reaching 120 metres, making it the tallest viaduct built on Corridor Vc. Of the other structures on the subsection, the Ričice and Pečuj tunnels and the Pehare Viaduct stand out.
On the Donja Gračanica – Zenica Tunnel subsection, the Donja Gračanica Viaduct and the Hum Tunnel stand out from other structures, and construction was carried out for the first time under “design and build” contract (design and build – yellow FIDIC). The works on this subsection were completed six months ahead of schedule.
In accordance with the agreements between JP Autoceste FBiH and the city of Zenica, the works on the rehabilitation of local roads used during the construction of the Zenica bypass are coming to an end. The construction of a four-kilometer local road and a bridge over the Bosna River will connect the city of Zenica with the M17 main road and the exit to the motorway.
Dionica Zenica jug – Sarajevo sjever je duga 51,5 km.
The Sarajevo North – Sarajevo West section serves as a bypass for the city of Sarajevo and is 9 km long. It is located in the northwestern part of Sarajevo and stretches through the Bosna River valley between the settlements of Jošanica and Vlakovo. This section was opened to traffic in June 2014.
The section was divided into two subsections: Sarajevo North – Butila (LOT 1) and Butila – Sarajevo West (LOT 3a).
The construction of this section cost a total of 80 million euros, excluding VAT, and the works were financed from credits from the European Investment Bank (EIB) and the European Bank for Reconstruction and Development (EBRD), OPEC and own funds of JP Autoceste FBiH.
The works were carried out by SCT Ljubljana and Euroasfalt and ŽGP, and supervision was carried out by DDC Slovenia, Divel, IGH, and Ipsa.
The Butila interchange is the largest structure on the Sarajevo bypass It was built in three levels with an area of over 20,000 m2. It was designed and constructed with four one-way ramps (two one-lane and two double-lane), allowing traffic from the direction of Zenica and Mostar to Sarajevo and vice versa.
The Sarajevo West – Tarčin section is 20 km long and was constructed from 2012 to 2014.
This section includes 5.5. km of tunnels and 1.5 km of bridges and viaducts. The most significant structure on the route is the 25th November Tunnel, which passes through the Suhodol hill, where the route reaches its highest altitude point of 665 metres above the sea level.
It was divided into three subsections: Sarajevo West – Lepenica, Lepenica – Suhodol and Suhodol – Tarčin.
The construction of this section cost a total of 369.5 million euros, excluding VAT, and the works were financed from credits from the European Investment Bank (EIB) and the European Bank for Reconstruction and Development (EBRD).
The works were carried out by Çengiz Inşaat and supervised was conducted by Egis International.
The section was opened for traffic in September 2014.
The Tarčin – Ivan section is 6.9 kilometres long and includes a new modern two-tube Ivan Tunnel with a length of 1.760 metres. The section Tarčin – Ivan is divided into two lots.
LOT 1, Tarčin – Entrance to Ivan Tunnel is 4.9 km long. The beginning of this subsection is at the end of the Lepenica – Tarčin section, immediately after the Tarčin interchange. In the first part of the relevant motorway, from the point of connection to the previous section up to the beginning of the M1 – Raštelica 1 bridge (L=518 m), the route runs for 1,200 metres on quite high embankments and reinforced soil.
After this sector, the route crosses the Raštelica 1 bridge to the opposite slope. The bridge crosses the M17 main road and the river Kalešnica. The bridge has 13 spans. After the left rest area, there is the M2 – Raštalica 2 bridge (L=589 m), which crosses the main road and the wider valley, so this bridge has 19 spans. It is important to note that at this location, the main road is on an incline, with three lanes (lane for slow vehicles). The right rest area, along with the entrance and exit ramps, is located from the area of the M2 bridge all the way to the entrance to the Ivan Tunnel.
The value of the contract for construction of the Tarčin – entrance to the Ivan Tunnel section is 66,584,028.92 euros, excluding VAT, and it was financed from the funds of the European Investment Bank (EIB) and grants approved by WBIF (EU funds) in the amount of 11, 7 million euros.
The Ivan Tunnel is a two-tube tunnel with two lanes and passes through the Ivan Sedlo mountain pass. The total length of the right tunnel tube is 1721.50 m, while the left tunnel tube is 1761.50 m long and is positioned beneath the existing Ivan Tunnel on the M-17 main road. The elevation at this location ranges from 500 to 1020 m, with a maximum overburden height above tunnel structure of approximately 200 m. Upon exiting the tunnel, the motorway route connects to the M-17 main road via a temporary road, marking the end of this section The temporary connecting road is a two-way road with one lane, approximately 700 m long. The connecting road starts from the future roundabout on the M-17 main road and continues uphill over an existing stream, crossing a 15 m long bridge, leading to the plateau of the Bradina side toll booth.
The value of the contract for construction of the Ivan Tunnel is 57,628,570.37 euros, excluding VAT. The funds were secured through the European Bank for Reconstruction and Development (EBRD) in the amount of 50 million euros and grants from the European Union in the amount of 11.4 million euros, which were secured as part of the Connectivity Agenda through the Western Balkans Investment Framework (WBIF).
The Počitelj – Zvirovići subsection is part of the Počitelj – Bijača section. It is 11.07 kilometres long.
During the construction, this subsection was divided into two lots.
The value of the contract (LOT 1 and LOT 2): 101,379,722.70 euros, excluding VAT
Funding source: the construction was financed from funds secured under a Loan Agreement with the European Investment Bank (EIB) and grants from the European Union, which were secured as part of the Connectivity Agenda through the Western Balkans Investment Framework (WBIF).
Along with the Hercegovina bridge (945 m) as the dominant object on the Počitelj – Zvirovići subsection, other significant facilities on the subsection include the Čapljina interchange with toll booth and access roads, an interregional junction, three viaducts, and the Herzegovina Tunnel.
The Međugorje – Bijača section is 10 km long. It represents a key infrastructural prerequisite for fully realising the economy, especially the tourism potential of southern Herzegovina.
The motorway from Međugorje to Bijača connects with the Croatian motorway Dalmatina.
There are two bridges on this section: Studenčica and Trebižat, the Pavlovići viaduct and the Bijela Vlaka Tunnel.
The Buna – Počitelj subsection is 7.2 km long. All the works have been completed and it will be opened to traffic after the completion of the subsections that are under construction.
This subsection is located between the Kvanj tunnel – Buna subsection on the northern side and the Počitelj – Zvirovići subsection on the southern side.
The route starts about four kilometres south of the village Hodbine and does not cross densely populated areas, but passes over the Neretva canyon near several populated areas and ends just before the Počitelj interchange.
Passing by the settlements of Stanojevići and Kevčići, the route cut off the road communication, which is why the Grabovina and Kevčići overpasses were constructed, and the underpass of the same name was built on the part of the route next to Bivolje Brdo. Among the other structures along the route are two wildlife crossings and a double-sided rest area Rotimski potok.
