The Dublin Link crosses the Scotio River in Downtown Dublin and is the longest span, single tower S-shaped suspension bridge in the world. Its steel superstructure passes through the “eye” of a cast-in-place concrete mast without any vertical support. The bridge is supported by an elaborate cable system including one tie-down cable, two main suspension cables, two restrainer cables and 38 hanger cables. schlaich bergermann partner was commissioned to provide an independent peer review, a constructability review, and erection engineering for the installation of the cable structure and erection sequencing.
