The landmark bridge, designed by Moxon, COWI and RPS, is part of Dublin Port’s 15-year scheme to increase capacity (link opens in new tab). The bridge is intended to form a symbolic gateway to the Southern Port Access Route (SPAR). It will also divert port traffic from the public road network to reduce congestion.

The single leaf bascule bridge is part of a 7km active travel network in the city. The primary active travel route is separated from motor vehicles by structural beams, while a secondary active travel route could be converted for use by the city’s tram system.

The main leaf aligns with the existing 30.5m navigation channel. A 20.5m channel has been maintained between the piers.

It is expected that construction will be completed in the late 2030s. The mechanical engineer for the project is Eadon.
