Built along the 82 km long motorway A1
between Orastie and Sibiu, in Romania, the Aciliu
Viaduct is one of the several infrastructures
planned to upgrade the IV Pan-European
corridor running through Eastern Europe. It
is also known as the longest and the highest
viaduct in Romania, with a height of 80 meters
and a length of 1.100 meters.
The Aciliu viaduct is made with inclined double-T beams in Corten steel, with welded longitudinal and transversal joints and bolted reticular internal bracings. The viaduct has a length of 1.100 meters, divided in fourteen spans 78 meters long, with a width of the deck of 24 meters. The structure dominates the Aciliu valley at a height of 80 meters from the ground and rests on concrete piles planted at a depth of 40 meters into the ground to offset the instability of the sandy soil of the valley.
