Summary

This multimillion euro upgrade of Dublin Port’s road network will significantly improve the existing road network within the Port, thereby providing Dublin Port Company with the capacity to deliver its Masterplan 2040 and handle major predicted increases in cargo traffic. 

The scheme comprises :

  • 1.5km of new roads
  • 1.5km of road reconstruction/resurfacing
  • four major junction upgrades, including three roundabouts
  • 3.7km of new truck queuing capacity
  • 1.9km of greenway (phase one)
  • four major surface water inceptors
  • a Port-wide signage project involving 50 new or replacement signs
  • introduction of improved pedestrian and cycle facilities
  • diversion or relaying of major utility services routes, including 220kV cables

ROD has been involved in the project since its inception in 2014, securing planning permission for the scheme in 2016 and managing the construction process from 2017 onwards. The works were procured and managed using the NEC3 form of contract, with ROD acting as both the project manager and the supervisor under the contract.

The other members of the project team include:

  • Kilwex Ltd. (main contractor)
  • SIAC (Enabling Works contractor)
  • Hugo Munro, James Wark (M&E)
  • Redscape, Austen Associates  (Landscape architects)
  • ThermalImage, KCA, John Dungan (Public lighting)
  • Darmody Architecture, TTT Landscape Architecture, Storyline, Cloake Brand Management, Cleary Connolly Artistic Consultants, Cundall (Lighting)

The road network elements are due to be completed in 2022. The greenway is expected to open in 2024.

Challenges

The project team faced several challenges over the course of the project, including:

  • delivering substantial improvements on a heavily trafficked, live road network
  • disruption caused by Brexit, which hit midway through the construction contract
  • poor ground conditions 
  • high water table next to the sea

To manage the complication posed by Brexit, with its potential to create queues and disruption in the Dublin Port network, ROD undertook extensive traffic modelling exercises to show impacts and potential traffic patterns. This led to modification of the Internal Roads Project ahead of the various Brexit deadlines. Changes included the creation of a new 200-metre relief road to relieve pressure on the main roundabout junction in the Port and to provide access to one of the new State Services Yards. 

Extensive and complex temporary works were required to manage the poor ground conditions and high water table next to the sea. 

Solution

In addition to the provision of 1.5km of new roads, the works included a new 300m, seven-lane truck queuing area for the roll-on / roll-off check-in booths. This area provides additional resilience for the port in the event of adverse weather or any other form of delays, and reduces the risk of queues propagating back from the port and causing disruption in the Dublin Tunnel and on the M50. 

Several junctions within the Port have also been upgraded, with roundabouts enlarged to more comfortably convey two lanes of traffic. In addition, existing roads within the Port have been resurfaced and lighting and services upgraded.

Ancillary works included the installation of petrol interceptors 7m below ground.

All the works were constructed in a sensitive manner, reflecting the importance of the surrounding bay for wildlife and Dublin Bay’s designations as a Special Area of Conservation (SAC), a Special Protection Area (SPA) for birds, and a UNESCO Biosphere. The provision of appropriate screening formed an important environmental commitment in the planning documentation, as it is essential to ensuring that impacts on birds are avoided.

Tolka Estuary Greenway

Running alongside part of the new road network is the Tolka Estuary Greenway, a 3.2km greenway that will allow the public to fully appreciate and enjoy the natural wonder of Dublin Bay.

Phase one, which runs 1.9km eastwards from East Point Business Park, is currently under construction by Dublin Port Company. It is due for completion in 2024.
