TRANSBIAGA TRANSPORTES USABIAGA, S.L. is a family company that began its activity more than 35 years ago in the transport sector, specialising in the transport of special and oversized loads.

Today it has a modern fleet of 50 tractor units and more than 250 semi-trailers, all by leading brands, which, combined with a team of highly qualified and experience professionals, means that it can offer both conventional and special transport services, with the only limitation being the actual thorough fares leading to them.

In addition to its transport services the company offers its clients the possibility of storing their goods at its logistics installations in Salvatierra-Agurain (Álava), Idiazabal and Arama (Gipuzkoa), all strategically located alongside the A-1 highway running from Madrid to France, where it has 5,000 m2 of covered space and 10,000 m2 of uncovered space.

Its headquarters are located in Arama (Gipuzkoa), scarcely 50 km from the border between Spain and France.

TRANSBIAGA has participated in all kinds of transport to develop the Spanish national highway and motorway network, in addition to all projects to establish the high speed railway network (AVE).Today it continues to be a benchmark in the field of special transport for civil work, entrusted with projects by the leading companies in the sector.
