I tried to start something similar on Victorian Alps seasonal road closures, for example <a href="https://www.openstreetmap.org/way/105842220">https://www.openstreetmap.org/way/105842220</a>. However these closures are usually described something like "closed to vehicles from Queens Birthday weekend to Cup Weekend" and are proving difficult to describe in OSM tag format without having to upload new dates each year.</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 9 Feb 2022 at 15:18, stevea <<a href="mailto:steveaOSM@softworkers.com">steveaOSM@softworkers.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">On Feb 8, 2022, at 8:08 PM, Graeme Fitzpatrick <<a href="mailto:graemefitz1@gmail.com" target="_blank">graemefitz1@gmail.com</a>> wrote:<br>

My "quick, off-the-cuff" answer would be: "better routers SHOULD." The real answer is very much "check your particular router."<br>
