How does a heavy transport from Portugal to Istanbul work?
A heavy transport from Portugal to Istanbul runs right across Western Europe: from the Iberian Peninsula via Spain and France, on through northern Italy and Slovenia onto the Balkan route as far as the Kapıkule border crossing. Depending on the loading point, the distance is around 4,000 to 4,500 km, with pure driving time of roughly one to two weeks. The overall transit time, however, is determined by the permit chain, not by the mileage.
Oversize Transports plans this lane as a complete project and first checks feasibility on the basis of weight, dimensions and axle loads.
Corridor: Iberia via France and Italy onto the Balkans
From Portugal, the route runs across the Spanish–Portuguese border at Vilar Formoso/Fuentes de Oñoro, on through Spain and via La Jonquera into France. From there, two variants lead south-east: either along the French Mediterranean coast and via Ventimiglia into northern Italy and, via Slovenia and Croatia, onto the Balkans, or northwards via Germany and Austria. Which variant is permissible depends on the height, width and weight of the cargo as well as on the approved routes. From Serbia, the classic Balkan route follows via Bulgaria to Kapıkule.
Permits: a separate procedure in every country
Portugal, Spain, France, Italy, Slovenia, Croatia, Serbia, Bulgaria and Turkey each require their own national special permit with their own lead times, requirements and, in some cases, route commitments. The German section of the route – if the northern variant is chosen – is applied for separately under §29 StVO (German road traffic regulations) via VEMAGS; all other countries have their own procedures, where §29 StVO does not apply. Because Serbia is not in the EU, an external EU border with full customs procedures arises there.
Customs: T1/TIR from the external EU border
Within the EU – from Portugal to the Serbian border – the consignment moves within the customs territory of the Union without border clearance. From Serbia onwards, the transport runs under the T1 transit procedure or under a TIR carnet; import clearance takes place in Turkey. We align the customs documents with the border posts in advance so that no waiting times arise at Kapıkule.
Equipment selection and load securing
The equipment selection follows the cargo strictly: low-bed or semi low-loaders for tall components, axle-reinforced modular trailers for heavy compact goods. On the winding coastal and mountain sections in southern France, Italy and Bulgaria, the clearance profile and turning radii are surveyed in advance. Loads are secured by positive and friction locking in line with recognised engineering standards.
Escorting along the route
Depending on the dimensions, we accompany the transport with our own escort vehicles up to BF3/BF4 escort. In several transit countries, a police or officially accredited escort is additionally mandatory, which we coordinate through local partners. Night and weekend driving bans feed into the scheduling.
Istanbul as the gateway to the Middle Corridor
Istanbul lies at the crossing point between Europe and Asia; for destinations on the Asian side, the Bosphorus crossing has to be clarified separately, as not all structures are cleared for heavy loads. At the same time, the city is the starting point for lanes along the Middle Corridor towards the Caucasus and Central Asia. Turkey-specific requirements can be found on our page on heavy haulage to Turkey.
Feasibility study as the first step
Before dispatch planning begins, we record weight, length, width, height and centre of gravity and derive from them the axle loads, vehicle type and permit requirements. The chosen route through Western Europe and the Balkans is checked for bridge capacity and bottlenecks. Only once equipment, route and permits fit together does execution start. Send us your project by phone or via the form – Oversize Transports, a brand of HSNK s.r.o. from Prague, will check feasibility.
Night driving bans and time windows
The transit time of this lane is strongly determined by time-related restrictions. Spain, France, Italy and the Balkan countries each have their own rules: in some countries, abnormal loads may only travel during daylight, in others weekend and public holiday driving bans are decisive. We interlock these windows with the opening hours of the border posts so that the transport does not wait at closed crossings. Particularly on the long west–east axis through several countries, this fine-tuning has a greater bearing on the overall transit time than the mileage alone.
Oversize Transports as an independent project partner
Oversize Transports is the brand of HSNK s.r.o., based in Prague, and acts as an independent heavy haulage forwarder – not as part of a network. For lanes such as Portugal–Istanbul we combine feasibility, routing, permits, escorting and customs in one hand and remain your point of contact across the entire route. This keeps the chain plannable, even when individual stages are only permitted within narrow time windows.
