Thanks for the links!

There are currently no physical or legal restrictions on car access. Based on ground truth, the road should remain tagged as service/unclassified until there are physical changes (e.g., signs, bollards, etc.).

If an estimated date had been provided, we could’ve added a start_date/end_date tag to plan a resurvey.
