Construction projects or emergencies that cause roads to be closed should be reported in the West Virginia forum, on the WV Closure Form, or by using the WME Form Filler Script (choose "WV Closures" in the pulldown). Current closures and events in West Virginia that have been reported to Waze are shown in the WV Closures Sheet.
Closures needing prompt attention may also be reported in the #west_virginia channel of the MAR Discord server. You will need to have a permalink to the segment(s) that need closed, the start time and the end time, and the reason for the closure.
See West Virginia/Closures for more details, along with information sources for road closures in West Virginia.
