Bridge under the railway with height restriction
Goalposts
Bridge Identification Plate with emergency contact details.
This is an example of a bridge with a height restriction under the railway. The sign below is a regulatory height restriction sign, which may appear on a height-restricted railway bridge. You must not pass unless your vehicle is lower than the height shown on the sign.
Height restriction
In the case of arch bridges, the indicated height is available only over a certain width of the arch. This width is shown by ‘goalposts’.
As you approach a bridge under the railway, you may see an advance warning sign such as the ‘restricted headroom’ sign below showing the height restriction that applies at the bridge. The height restriction is written first in feet and inches and then in metres.
