The Viaduto do Corgo is a 2,796-meter-long cable-stayed bridge of the A 4 Auto-Estrada Transmontana in Portugal . With a maximum road height of 230 meters, it is the fourth highest motorway bridge in Europe. The bridge slab was completed on March 15, 2013. The opening took place in the same year.

The structure is located in the Trás-os-Montes region , where it crosses the Corgo River , a tributary of the Douro , south of Vila Real . The bridge drops sharply towards the middle of the deeply cut valley, with the maximum gradient on both sides being five percent. The superstructure runs on slender pillars that are 60 meters apart. Somewhat off-center is a section between the pillars 15 and 22, which is built as a cable-stayed bridge with two pylons , the span of this central part is 300 meters and the pylons protrude 70 m above the roadway. The length of the western fore bridge is 855 meters, that of the eastern 1167 m.

The bridge carries a four-lane motorway with hard shoulder. The dividing strip is provided with a concrete protective wall, there are walkways on both sides. The entire deck is 28 meters wide, the lanes 3.5 meters, the hard shoulder 3 meters and the footpath 1.25 meters. It lies on a box girder with side cantilever arms supported by struts. The pillars are kept as slim as possible because of the great height.
