𝗢𝘃𝗶𝗲𝗱𝗼 𝗲𝘀𝘁𝗿𝗲𝗻𝗮 𝗲𝗹 𝗔𝗿𝗽𝗮 𝗱𝗲 𝗦𝗮𝗻𝘁𝘂𝗹𝗹𝗮𝗻𝗼 El alcalde de #Oviedo, Alfredo Canteli, inauguró el pasado julio la reforma de la margen derecha del Bulevar, que mejoran la conexión entre los barrios de Ventanielles y La Monxina. La obra, iniciada en mayo del año pasado incluye una pasarela atirantada, casi un kilómetro de sendas peatonales y ciclistas, áreas de juegos infantiles, zonas de ejercicio y elementos decorativos que llegan hasta la plaza de la Cruz Roja. La #pasarela, conocida como el Arpa de Santullano, es el elemento más singular del #proyecto y tiene la función de conectar los barrios que actualmente están divididos por la autopista. Esta conexión se resuelve mediante un #tablero metálico con chapa ortótropa de sección lenticular (definido a través de una línea poligonal), que sigue una circunferencia de 33 m de radio, 84.5 m de longitud y 5.3 m de ancho; y está soportado por 20 #péndolas que lo atan a un #pilono de 55 m. La pasarela es un proyecto de CARLOS FERNANDEZ CASADO, S.L. (CFCSL), LFG (Luis Fernán González Saiz) y Hualca Ingenieros, ha sido ejecutada por la empresa Vías y Construcciones S.A. el suministrador de las péndolas es DYWIDAG y los medios auxiliares han sido proporcionados por Grúas Roxu - Grúas autopropulsadas, gran tonelaje, plataformas elevadoras, transporte, drones.

𝗜𝗻𝘁𝗿𝗼𝗱𝘂𝗰𝗶𝗻𝗴 𝘁𝗵𝗲 𝗦𝗮𝗻𝘁𝘂𝗹𝗹𝗮𝗻𝗼 𝗙𝗼𝗼𝘁𝗯𝗿𝗶𝗱𝗴𝗲 The city of Oviedo (North Spain) is set to inaugurate a new landmark: the Santullano Footbridge. Spanning 84.5 metres in length and crossing 64 metres over the A-66 highway, this bridge is a key element of the urban redevelopment project, transforming the highway into a green, pedestrian-friendly space. Javier Muñoz-Rojas is the lead designer of this footbridge, and I had the pleasure of working with him to find the right form of the structure and finalise the design. My colleagues and esteemed mentors at CFC have a long history of creating special curved footbridges, such as (also see the images): - The Malecón footbridge in Murcia - The footbridge over the Manzanares river in Madrid - The footbridge over the Ebro river (Volunateriado)- Expo 2008 in Zaragoza What sets the Santullano Footbridge apart from previous designs by CFC is the elimination of stabilising cables usually necessary for the pylon. We worked on achieving this through a cable-stay system that supports the deck, placing the tower in a position that minimises the horizontal components of the cable loads from any direction. This setup, refined through iterative parametric studies, offers a heightened sense of lightness and dynamism. With the principles of tensegrity in mind, I enjoyed optimising the cable arrangement and positioning the pylon to eliminate bending moments. This project was incredibly rewarding and special to me, even though it required as much effort as developing a 200-300 metre cable-stayed bridge. It was refreshing to step out of the ordinary and create a new form, challenging and expanding my understanding of structural design. I would also like to thank our very talented engineer Gonzalo Marinas Sanz for his work in developing the special abutments and various aspects of this project, Luis Fernán González Saiz for his collaboration throughout the entire project, and Carlos Herrero for his work on the detailed drawings and BIM.
