Alcantara Dam, Spain

ALE was engaged to assist with the construction of a viaduct on La Plata highway over the Tajo River.

The viaduct consists of two main sections with a total length of nearly 400 metres. The sections are supported on concrete pillars rising from the banks of the river and on steel arches in the centre. The arches span 220 metres and are 42.6 metres high.

ALE’s responsibilities included pushing the bridge sections into place, skidding the steel arches over the bridge and lowering them into position, tilting and closing the semi arches, skidding the semidecks from both abutments and replacing the temporary supports with the final supports.
