MUTCD/Michigan/W
Series W of the MMUTCD is for warning signs. The following tables display only the signs specific to the MMUTCD in Michigan; consult MUTCD/W for warning signs in the national standard.
Work zone usage
This series includes temporary traffic control warning signs for use in work zones (construction zones). Whereas a regulatory sign appears the same inside and outside a work zone, a warning sign has an orange background instead of the usual yellow when used in a work zone.

Warning use
Work zone use
In general, OpenStreetMap only maps long-term closures and construction sites. For routing purposes, short-term construction is more reliably and efficiently tracked in incident management systems along with real-time traffic congestion data. However, if a temporary sign happens to be posted on a long-term basis for some reason, you can map it as you would map a normal sign. If you map the work zone use traffic sign as a node, use a W code but add colour=orange to the node.
