The mass downloading of highways happened 6 years before OSM started, so they've always been under this classification. Also highways doesn't necessarily mean freeways (400-Series) - some of these highways were 2 lane country roads at the time that could now be maintained by the growing suburban population and were no longer as relevant with the expansion of the 400-Series system.</div><div><br></div><div>A Canadian-specific specification would be nice to have defined.

So in the case of some primaries in the GTA that are former provincial highways, not adding a suffix such as CR or RR to distinguish it from provincial highways (this being the likes of the 401, the 407 and the other 400-series highways) would result in a provincial highway shield being rendered instead of a regional or county road shield. Maybe also a consideration for provincial highways that use TCH sign except in Ontario and Quebec.</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 1, 2022 at 9:40 PM Brian M.
