This has to be the most photographed bridge in Ireland.

The bridge joins Sir John Rogerson's Quay on the south side of the River Liffey to Guild Street and North Wall Quay in the Docklands area.

The architect is Santiago Calatrava, a designer of a number of innovative bridges and buildings. This is the second bridge in the area designed by Calatrava, the first being the James Joyce Bridge, which is further upstream.

Constructed by a "Graham Hollandia Joint Venture", the main span of the Samuel Beckett Bridge is supported by 31 cable stays from a doubly back-stayed single forward arc tubular tapered spar, with decking provided for four traffic and two pedestrian lanes. It is also capable of opening through an angle of 90 degrees allowing ships to pass through. This is achieved through a rotational mechanism housed in the base of the pylon.

The shape of the spar and its cables is said to evoke an image of a harp lying on its edge.
