The sign for a hump bridge -- or as it is more commonly known, a hump-backed bridge -- is used where the presence of an arch bridge ahead creates a significant change in gradient for traffic crossing the bridge. Smaller hump bridges, such as those on the Somerset Levels where the road has often subsided on either side of the bridge structure, are more commonly indicated by means of the Uneven Road sign.

Pre-Worboys

1954 Highway Code - Hump bridge.jpg

Before the Worboys Report, warning of a hump-backed bridge ahead was provided by a black-on white plate bearing a bridge symbol and the words "Hump Bridge" beneath a hollow red triangle. Practically all of these signs have since been removed and replaced by their modern equivalent.

Post-Worboys

Today's hump-backed bridge sign features the silhouette of a hump-backed bridge within a red warning triangle. It should be noted that by no means are all hump bridges in the UK are preceded by this sign! A supplementary plate indicating the distance to the bridge may be used where it is located on the far side of an intermediate bend or is otherwise hidden.

Ireland

The Irish equivalent is warning sign W 132 Humpback Bridge (Traffic Signs Manual 2010). The symbol used is very similar to that employed in the UK version, although placed, of course, on a yellow diamond background.
