Learn More 🚀The Opening or Swing Bridge Ahead Warning Sign – Diagram 529 is a crucial UK traffic sign that alerts drivers to the presence of a moveable bridge ahead. These bridges, which may open to allow boat traffic to pass, require drivers to approach with caution and be prepared to stop, particularly where visibility or signage is limited.
Designed in strict accordance with TSRGD Diagram 529, this warning sign meets BS EN 12899-1 and Chapter 4 standards for road signage. Manufactured from high-durability aluminium, composite, or sticker substrates, the sign is available in RA2 or R3B reflective finishes to ensure clear visibility in all light conditions.
Choose from the full UK-standard triangle sizes — 450mm to 1500mm — with options for channel mounting, plate-only fixing, or self-adhesive application, making it ideal for both permanent installations and temporary setups near river crossings and quaysides.
This sign features a bold graphical symbol of a raised bridge span above stylised water waves, framed within the traditional red-bordered triangle. Its instantly recognisable design communicates imminent mechanical bridge action, helping reduce collision and stop-related incidents.
