A viaduct is a type of road or railroad bridge with multiple bays. Beams are usually the main elements forming a bridge structure. While mounting, they are arranged parallel to the road in order to support the carriageway. This type of elements, broadly characterised by high performance in terms of loads and spans, usually have significant weights and sizes combined with a high prestressing stretch. For these reasons, transporting them from the production plant to the erecting yard is often complex and expensive. Thus, it can be more advantageous to produce them on site, which however involves the use of production lines that are easily transportable and require limited foundation building works. Bridge beams can be used for works in road and/or railroad sector and have several geometries.
