Abstract
To link up the Central Europe and the Southern Europe road system across the Alps, a road bridge has been recently built, which runs 190 m above the bottom of the valley of the Sill river. This structure has been named the Europa Bridge. The Brenner Pass is very suitable for winter traffic by road, in spite of its height of 1370 m above sea level. The bridge deck consists of a metallic box girder. The total length of 657 ms has been divided into six spans. Three of them are 91 m long, two are 108 m long, and the central span is 198 m long. The main features of this bridge are its supports, which rise to a height far above anything so far previously attempted. The highest pile is 160 m long, from the ground to the deck. The piles are hollow inside, and have been internally divided by means of two partitions, which extend throughout the total height. Horizontal thrust is allowed for by a series of horizontal diaphragms, spaced every 20 m. Due to the accumulation, on the surface of the valley, of thick layers of surface soil carried down by the river, the foundations have had to be established at a great depth. The piles have been built with the aid of sliding formwork. The design and erection of the bridge has been done by the Vereinigte Osterreichische Eisen un Stahlwerke, AG., and the work was directed by Ing. Dipl. Josef Gruber.

Continente a través del Paso del Brenner, en los Alpes î austro-italianos, se ha construido recientemente un puente j para carretera—con u n a altura de 190 m sobre el fondo del valle del río Sill—denominado Puente de Europa.
Los 657 m de longitud total del puente propiamente dicho se han subdividido en seis tram o s : tres de 81, dos de 108 y uno central de 198 m de luz.
—que el puente salva en su tramo central de 198 m de luz—, los cimientos de las pilas han tenido que descender a gran profundidad.
