Thanks for the quick response.
There is a large construction site here, with a link road which has been marked ‘construction’:
I’m not sure in OSM if ‘construction’ means ‘under construction’ or a ‘construction vehicle route’…possibly could be either in different contexts. I noticed there is also a ‘proposed’ category - which could be a planned road which is not yet under construction or may not be developed.
Either way I think there is a use case (albeit an uncommon one) - such as directing construction vehicles or deliveries into a construction site.
working on resolving such temporal restrictions to give an option to query for a route on a defined date in the future.
This would be awesome - curious to see how OSM handles temporal changes (e.g. new roads).
