Abstract: 
Since UHPFRC is a very expensive material, it is necessary to optimize structural system designs to consider UHPFRC as an alternative competitive material in structural applications. This process leads to UHPFRC lightweight structures that minimize the concrete needs. These new solutions are more similar to steel than concrete, and offer an improvement in durability and aesthetics properties as compared to steel structures.

The U-shaped Truss Footbridge over the Ovejas ravine in Alicante, devised only in UHPFRC with 45-metre span, has replaced a previous design in steel due to many factors such as its low cost; its expected high durability inside an aggressive environment close to the sea; and its aesthetics enhancement. This footbridge is probably going to be the first truss pedestrian bridge in which all the structural elements are made only of UHPFRC, as far as we know.

In this paper, the construction stages, some issues found during the mixing process in a precasting factory, and the footbridge current state of the construction process are presented.
