A flagship project for IBERTAL that started in October 2003 and ended in December 2005.

Inaugurated on 31 October 1886, the rehabilitation for the tranvia (metro) rails deserved a highly technical and elaborate plan of reconstruction, on which IBERTAL played an important role in providing skilled labor to perform that important work.

Today, Oporto is proud to maintain an asset in the most beautiful and ancient bridges over a river, serving as a link between the cities of Oporto and Gaia.
