Railway bridges signs
Warning signs
As you approach a bridge, you will see a warning sign, such as the sign below, showing the highest vehicle that will be able to pass under the bridge. The height is called the maximum headroom and is written first in feet and inches and then in metres.

Low bridge ahead
(height restriction show)
If your vehicle, including any load being carried, is higher than the height shown on the warning sign, you will not fit under the bridge ahead. It is very important to know the height of your vehicle and of any load being carried before you start your journey � know your height, know your route.
Information signs
You must report all incidents of striking any railway structure whether or not damage is obvious. The information signs shown below appear on bridges and give the code for the bridge and a local Iarnrod Eireann contact phone number.

Advance information sign for low clearance
Regulatory signs
The sign below is a regulatory height restriction sign, which may appear on a railway bridge. You must not pass one of these if your vehicle is higher than the height shown on the sign.

Height restriction
In the case of arch bridges, the signposted height is available only over a certain width of the arch. This width is shown by 'goalposts'.

Height restriction
Where the rail line is located under a bridge and vehicles can cross a roadway on top of the bridge there can be restrictions on vehicles entitled to use the bridge.
Overhead structures
You must report any striking of any overhead structure by your vehicle or by any load wherever the above regulatory sign has been provided. Structures include any bridge, viaduct, subway, underpass, overpass, flyover or tunnel.
