Ratoath Road Realignment and Overbridge to Replace Reilly’s Bridge, Co. Dublin

The Ratoath Road links Cabra to Dunsink in north Dublin. The road crosses the Dublin to Sligo Railway Line at a level crossing and the Royal Canal at an existing masonry arch bridge. For the reasons described below, an April 2008 feasibility study recommended the closure of the level crossing, XG002.
Increased future traffic is expected along this section of the railway line due to the following:

  • Opening of the Spencer Dock Station in Dublin’s docklands 
  • Reopening of the Clonsilla to Pace sections of the Dublin to Navan Railway Line 
  • Reopening of the Pace to Navan sections of the Dublin to Navan Railway Line.
  • Improvement in Commuter and Intercity services on the Dublin to Sligo Line
  • Proposal for the DART Underground project between Docklands and Inchicore
  • Future electrification of the Maynooth Line

The increase in rail traffic will contribute to the delays experienced by road users at the level crossing. Safety of road users is compromised by the sharp bends and poor vertical alignment at the canal bridge and the lack of pedestrian facilities at the level crossing. Also, no separate cycle facilities are currently available.
For the above reasons, Roughan & O’Donovan Consulting Engineers were commissioned by Iarnród Éireann to design a scheme to eliminate the level crossing.

The proposed scheme incorporates the following major elements:

  • Traffic, cycle and pedestrian facilities along the 500m of realigned road
  • Tie-in to the existing Ratoath Road at Marian School, circa 240m south of the level crossing
  • Landscaped embankment on the southern approach to the bridge constructed on the grassed area to the east of the existing road
  • A 70m long single span steel truss bridge crossing the railway and the canal
  • Reinforced earth walled embankment along the open land between the existing commercial units to the north of the bridge
  • Pedestrian ramped access to the canal from the north west side of the bridge
  • A revised signalised arrangement of the Ballyboggan Road junction
  • Closure of the existing XG002 Reilly’s level crossing

The scheme was approved by An Bord Pleanála in July 2011.

Iarnród Éireann appointed BAM Civil Ltd. as contractors for the scheme. Work commenced on site in July 2013 and is expected to be completed by early 2015. The scheme is being supervised by Roughan & O Donovan Consulting Engineers on behalf of Iarnród Éireann and is being funded by the National Transport Authority.

An Environmental Impact Statement (EIS) was prepared for the scheme and a copy of the Non Technical Summary EIS is attached together with Preliminary Design Drawings of the scheme.
