SWL (Single White Line)

What is SWL (Single White Line)?

Definition of SWL (Single White Line) in Construction

Although the term SWL means single white line, this abbreviation is in many cases a consistently repetitive questionable description, on a site document. Unless the abbreviation is actually looked up on the document index, if there is one, it always has a tendency to confuse, even the most seasoned contractors and interpreters of construction documents. Like the abbreviation for a double white line ( DWL ), the SWL abbreviation is too simple to be remembered. All it basically identifies is the painting of a SWL (single white line) on the pavement, or the any other hard surface. Normally the site plan will be the document that will include this abbreviation.
