The new single-leaf bascule bridge at Dublin Port promises innovative engineering solutions and infrastructure improvements.
- Designed by Cowi, Moxon, and RPS, the bridge is a pivotal element in Dublin Port’s Masterplan 2040, enhancing connectivity across the River Liffey.
- The bridge features an innovative opening mechanism, using a reconstituted granite counterweight to reduce energy use and carbon emissions.
- The crossing will facilitate active travel, accommodating both cyclists and pedestrians, and potentially Dublin’s Luas tram system.
- Construction of the bridge, a crucial part of the 3FM project, will bolster Dublin’s transport infrastructure and support the city’s export ambitions.
The new single-leaf bascule bridge, engineered by Cowi, Moxon, and RPS, is poised to significantly impact Dublin Port as part of its expansive €1.1bn Masterplan 2040. Situated across the River Liffey, the bridge’s design incorporates a unique opening mechanism that is both innovative and sustainable. The use of a reconstituted granite counterweight, supported by reclining steel arms, facilitates a ‘choreographed opening sequence’ which enhances the bridge’s operational efficiency. This sophisticated mechanism permits the counterweight to engage early in the opening sequence, thereby reducing energy consumption and lowering carbon emissions compared to traditional designs.
The main leaf of the bridge aligns seamlessly with the existing 30.5m wide navigation channel, allowing the unobstructed passage of ships. Furthermore, an additional 20.5m navigational channel serves the local community, improving accessibility and aligning harmoniously with the nearby Tom Clarke Bridge. This strategic alignment is part of a broader vision encapsulated in the Southern Port Access Route (SPAR), designed to relieve congestion on public roads and promote sustainable travel options.
As a new landmark, the bridge not only facilitates port traffic diverting it from public networks but also integrates a 7km network of cycle and pedestrian routes across the Poolbeg Peninsula and River Liffey. This inclusion supports active travel, with upstand structural beams separating pedestrian and cyclist paths from vehicular traffic, enhancing safety. The eastern side of the crossing offers an uninterrupted sea view, potentially accommodating Dublin’s Luas tram system in future developments.
This infrastructure project, the easternmost road bridge across the River Liffey, is integral to delivering the increased capacity envisioned in the 3FM project, the third phase of the Dublin Port Masterplan 2040. The bridge will expedite the transport of containers from the port to a nearby rail facility, thereby increasing efficiency and responding to growing demands for freight services between Ireland and Continental Europe.
Official statements from those involved in the project, including Moxon associate Richard Thebridge and Cowi UK project director Oliver Stross, highlight the structural and environmental advancements represented by the new bridge. They express confidence that these innovations will not only meet local community needs, offering new public amenities and enhancing travel routes, but will also contribute significantly to Ireland’s export capabilities in coming years.
The new single-leaf bascule bridge at Dublin Port represents a landmark leap in engineering innovation and infrastructure development.
