The Samuel Beckett Bridge is one of the many bridges that crosses over the River Liffey in Dublin, Ireland. It joins Sir John Rogerson’s Quay on the south side to Guild Street and North Wall Quay in the Docklands area. The bridge was named after Samuel Beckett, Nobel Laureate, to complement the sister bridge, James Joyce, located up stream. It is a...
Cross section of the deck
The width of the bridge is around 27 m, and it has two pedestrian and cycle tracks plus four lanes for vehicles. Two of these lanes can be adapted to accommodate trams in the future. It is a steel multi-cell box girder from which the ribs and steel decking forming the pedestrian and cycle tracks cantilever. The top plate of the box is only 14 mm thick, but it has 12 mm trapezoidal stiffeners every 0.5 m. The back span houses the counterbalance (concrete and steel) and the plates are not stiff...
Cables
The cable-stays are locked coil cables, that is, they are formed by strands arranged in concentric layers about a central one. The front span is supported by 25 cables of 60 mm in diameter set in a ‘harp’ formation. There are 6 stronger cables in the back with a diameter of 145 mm.
Pylon and foundation
Its support consists of a circular concrete pier of varying diameter sitting on a foundation made out of bored concrete piles and a concrete pile cap. The concrete pier has an outer diameter of 8,6 m at the base and 15 m at the top, with a height of 10 m. Inside, there is a 10 m long central steel tube with a diameter of 2,5 m and a plate thickness of 120 mm, which is welded to the deck below the base of the pylon, to transfer the load to the pile cap below. There is a main vertical bearing a...
When the bridge is closed, it sits on a continuous horizontal elastomeric bearing ring on the rim of the support pier, and it is kept into position by two pairs of locking pins at each end, that are inserted into housings cast into the abutments. The expansion joints at each end of the bridge are formed by movable steel boxes, which are controlled ...
This special bridge was designed for two different situations, as it has to resist live loads (traffic and pedestrians) when closed, but it also has to bear its own weight when it’s opened and only supported on the pylon. The worst case of analysis is the opened situation, where forces and deflection of pylon and deck had to be minimized by designi...
The construction started with an installation of a 20 m square AZ46 sheet piled cofferdam, driven to the top of the bedrock (about 3 m deep in the soil), in order to build the foundation. Walers and struts were progressively installed as the cofferdam was dewatered. It was necessary to place concrete as a bottom strut before the cofferdam could be ...

The Samuel Beckett Bridge by architect Santiago Calatrava was built in Dublin, Ireland in 2007-2009.

The Samuel Beckett bridge is a cable stayed, steel box girder structure with a span of 123 meters over the Liffey, which rotates through 90 degrees. The pylon curves northwards to a point 48 meters above the water level with 25 cables set in a harp formation.
The alignment of the proposed structure with Pearse Street establishes a physical connection to the core of the city, whilst establishing a (meta)physical connection with the (re)surgent city to the north of the river (liffey). The bridge is, from this point of view capable of weaving the city together and act as a new nodal point for the ...
The Samuel Beckett bridge is a cable stayed, steel box girder structure with a span of 123m over the Liffey. Designed by Santiago Calatrava in conjunction with Roughan O’Donovan (Dublin); the bridge was built by Graham Hollandia Joint Venture Contractors.
Designed by a well-known Spanish architect Santiago Calatrava, it is one of three bridges planned to be built over the Trinity, the second is the Margaret McDermott Bridge, is currently under construction. The span parallels the Continental Avenue Bridge, a walking bridge.
