CRISTO DE LA EXPIRACIÓN BRIDGE (CACHORRO) SEVILLE
ROLE: PROJECT MANAGEMENT & DETAILED DESIGN
The founder of Ayesa, José Luis Manzanares Japón designed this 225-metre deck-arch bridge. This urban structure is known as the Cristo de la Expiración Bridge (or the Cachorro Bridge) and serves both vehicular and pedestrian traffic. The chronology of this bridge dates back to 1948 when the river became blocked, creating a landmass called the Chapina Blockage, In 1992, the Chapina river earth-plug/landmass was redeveloped into a new bridge to cater for increased vehicular traffic and a new bus station. Inspired by the Pont Alexander III Bridge in Paris, the bridge is of metallic structure, with lower parallel wishbone arches with an overhead deck of orthotropic sheets, and dual labelled pylons.

“A bridge is not just a connector or a transport enabler, it can help the local economy, become a tourist attraction, a cultural icon, an inspiration, a work of art, or a much-loved part of a town or city where communities like to congregate. “
PUENTE DEL DRAGÓN, “DRAGON BRIDGE” | SPAIN
ROLE: DESIGN, TENDER, PROJECT MANAGEMENT
Designed by the founder of Ayesa, José Luis Manzanares Japón, this structure was inspired by local history and culture. This unique design won the public vote in response to a design competition. This bridge is located in the historical town of Alcala de Guadaira, 9km from Seville city. “The Guardian of the Castle” consists of a four-span bridge supporting a curve in the vertical plane, the directrix of which creates the figure of a dragon. In contrast, the bridge’s two carriageways sit on both sides of the directrix. In 2020, Spain’s postal service issued a limited-edition stamp with an image of this iconic bridge. The Dragon Bridge undulates above and below the street level, straddles two hills and is the first figurative bridge in Spain and Europe. The beauty of the construction is indisputable, as well as the simplicity of its structural performance, where a central beam is supported on three pillars and two extremes, upon which the pedestrian walkways have been cantilevered.

SECOND VIVEKANANDA BRIDGE (NIVEDITA SETU) | INDIA
ROLE: OPERATIONS & MAINTENANCE MANAGEMENT, TECHNICAL ASSISTANCE
The caretaking of bridges changes over time. Every stage has different requirements to ensure they last their entire lifecycle; they could typically include services such as surveying and inspection, Intelligent Bridge Life Systems, corrosion protection and strengthening. Our remit included the inspection, assessment, and advice/recommendations on rehabilitation, protection/strengthening and additional extensions. The following elements of the structure were rigorously assessed and checked as part of our brief: the bridge, the 3.65km Howrah approach viaduct, the 1.57km Kolkata approach viaduct, ROB, RUB approach embankment, culverts, underpasses and the toll plaza. The main bridge comprises 6 traffic lanes (29m wide deck) and 880m long (extradosed cable-stayed segmental bridge). Click here for more project information.

PANAMA CANAL BRIDGE | PANAMA
ROLE: INDEPENDENT ENGINEER, DESIGN REVIEW, PROCUREMENT SUPPORT, SUPERVISION AND COORDINATION
The Fourth Bridge over the Panama Canal is being constructed on the north side of the existing Bridge of the Americas to connect west Panama with Panama City. The new bridge will relieve vehicular traffic congestion and increase freight transport capacity and improve vessel navigation. It is estimated that more than 70,000 vehicles will use the bridge and that it will benefit 1.7 million people.

AN COMPANY ROYAL COMMISSION BRIDGES
ROLE: GROUND INVESTIGATION, DETAILED BRIDGE DESIGN & CONSTRUCTION METHODS
The Royal Commission in Jubail (RCJ) were constructing two new bridges: one from Jalmudah to Al-Batinah Island (Battinah) and the other from Dareen to a nearby island (Dareen). Batinah is a 4-lane bridge and Darren is a 2-lane bridge designed to replace a smaller existing bridge to link the mainland to oil production facilities. Both bridges have been designed with a 60m main span to clear a 40m navigational channel to allow safe navigation of vessels up to 15m in length. ByrneLooby in association with FAEC were commissioned to provide detailed design of the bridges, the approach causeways, the marine works including lining the channel, protection for the piers, and navigation aids. Detailed assessments included a detailed study for the form, shape and location of both bridges. Extensive geotechnical investigations were carried out to ensure the optimum piling solution was found for all piers in varying ground conditions. Extensive studies investigated possible construction methods for the pile caps and piers in the marine environment. Both bridges were designed using post-tensioned concrete box girders of uniform depth – each carrying 2 lanes of traffic, with inclined piers supporting the spans over water and vertical piers for spans over mud flats. Services included: bridge structures, causeways, embankments, shoreline protection, roads, deep foundations, subgrade improvements, design vessels and collision loading. We also supervised the ground investigation works.
