The Lueg Viaduct is the longest bridge on the A13 Brenner motorway in Tyrol with a length of almost 1.7 kilometers and it is highly strategic for its position and for the number of vehicles passing over it every day, estimated to 32.000 vehicles per day.

The Luegbrücke is divided in five sections with a height from the ground up to 60 meters. The first four sections are composed by two box girders connected by transverse beams and will be delivered in exceptional transports and lifted in their final position. The final bridge is a box with a variable section and will be assembled on a temporary deck and moved from there in its final position.
