Humpback Bridge Sign – W 132 | Permanent Ireland Traffic Sign
The Humpback Bridge Sign – W 132 is a critical traffic warning sign used to alert drivers of an upcoming humpback bridge, characterised by its steep approach and sharp gradient over a narrow or arched span. This high-visibility sign features a distinctive bridge silhouette on a yellow diamond background, ensuring early driver awareness in advance of the bridge.
In accordance with Chapter 5 of the Traffic Signs Manual (TSM), the W 132 sign is deployed on approaches to humpback bridges to reduce the risk of speeding, loss of control, or reduced visibility of oncoming vehicles. These bridges are often found in rural or heritage areas and may have limited width or restricted sightlines.
This sign prompts drivers to reduce speed, remain cautious, and be alert for vehicles coming from the opposite direction. It enhances road safety in environments where steep gradients or narrow structures pose a risk to motorists, cyclists, and pedestrians alike.
