NARROW STRUCTURE Sign

NARROW STRUCTURE Traffic Sign

The purpose of the NARROW STRUCTURE sign is to indicate:

- A decrease in the width of the roadway, resulting from a structure that is narrower than the approach roadway width; or

- A structure having a clear roadway width of less than 6 m.

The oversize NARROW STRUCTURE sign (WA-124) should be used where the posted speed is 70 km/h or greater.
