Reilly’s Bridge

Roughan & O’Donovan designed this scheme to eliminate a level crossing along the Maynooth railway line and relieve traffic congestion for road users at the crossing.

Our design solution involved:

• closing the existing level crossing
• constructing a 70m long, single-span, steel truss bridge crossing
• making provision for traffic, cycle and pedestrian facilities along 500m of the realigned Ratoath road

• The Royal Canal, as a proposed Natural Heritage Area (pNHA)
• The built-up nature of the site
• Close proximity of residential dwellings

We succeeded in:

• Reducing the visual impact of the bridge by minimising the height of approach embankments
• Complementing the industrial heritage of Dublin’s rail network by achieving a truss form with our bridge design
• Minimising operational risk to the railway by facilitating offline assembly
• Maximising commercial land to the north by using reinforced earth embankments
• Relieving road traffic congestion with our revised signalised arrangement of the Ballyboggan Road junction
