600x600mm Narrow Underpass Sign | Roadworks

The Narrow Underpass sign is a specialised warning marker used to alert motorists to restricted overhead or lateral clearances. It belongs in roadworks zones, tunnel entrances, and narrow bridge crossings where vehicle operators encounter during daily transit. By clearly marking the approach to a constrained space, it helps prevent vehicle strikes and structural damage in high-traffic environments.

Installing these road signs reduces the risk of oversized vehicles attempting to enter an underpass that cannot accommodate their width. The Class 1 reflective surface ensures that the warning is visible to drivers during night operations or in low-light weather conditions, giving them ample time to slow down or divert. This is particularly useful for site supervisors and traffic controllers who need to manage the flow of heavy machinery and transport trucks through tight urban or industrial corridors without constant manual spotting.

Constructed from durable aluminium, the sign measures 600x600mm to provide a clear, legible warning from a distance. The combination of a rigid metal build and reflective coating makes it a reliable choice for permanent or temporary roadworks installations.
