What we do

Roughan & O'Donovan has designed more than 70 rail bridges since 2002.  

Our over and under railway bridge design solutions integrate our expertise in construction methodology, inspection, assessment and rehabilitation.

Advisory services

We advise railway owners on the implementation of design standards, such as the Eurocodes, helping them achieve compliance with Irish and European legal requirements for the Authorisation for Placing in Service (APIS) railway infrastructure.


Our rail team is experienced in managing the interface between road and rail infrastructure and conducting emergency structural investigations.  We also support third-party clients in their engagement with railway operators and regulators.

  • The Reilly's Bridge scheme improved commuter and intercity services on the Dublin-Sligo rail line and relieved traffic congestion on Ratoath Road.
