Roughan & O'Donovan has a dedicated Rail team providing design services to Iarnród Éireann (Irish Rail), and has also undertaken major projects for the Railway Procurement Agency (RPA) for light rail infrastructure.  One such project is the William J Dargan LUAS (light rail) bridge in Dublin, undertaken for the RPA. This tall tower cable-stayed bridge has a main span in excess of 100 meters and was constructed across a live traffic junction.

Our work for Iarnród Éireann includes a number of long-term framework commissions. One such appointment is the level crossing replacement programme where Roughan & O'Donovan has
designed and administered the construction of over 20 rail bridges with a large number currently in design.  The Rail team has also designed a number of rail bridges on major roads projects for design-build contractors including three such bridges on the N9 Phase 4 contract for Sisk-Roadbridge.
