Railway bridges and overhead structures

Introduction

A railway bridge is a structure where a road or passage crosses a railway track by a bridge either under or over the railway. As you approach a railway bridge, you must obey any signs and roadway markings.

You will see an information notice similar to the one shown below on railway bridges. This sign plate gives an identification number for the bridge and Iarnród Éireann’s emergency contact phone number.

This bridge

identification number is different for each railway bridge

Example Railway Bridge Identification Plate

Emergency actions – reporting bridge incidents

You must report immediately any incident of your vehicle striking a railway bridge or structure whether or not damage is obvious. Drivers must use the emergency telephone number to contact Iarnród Eireann following any incident at a bridge, stating the nature of the incident and the bridge identification number on the sign.

If you cannot make contact immediately at this number, you must immediately notify a member of An Garda Síochána.

Failure to do so is an offence.
