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; and making provision for traffic, cycle and pedestrian facilities along 500m of the realigned Ratoath road.
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
- The Royal Canal, as a proposed Natural Heritage Area (pNHA)
- The built-up nature of the site
- Close proximity of residential dwellings
