2022-12-21: I've re-worked the traffic circle (previous build had some disconnected pathways) according to several roundabout tutorials and OSM wiki. However, testing a car navigation route across HWY 9 routes north and around, rather than through the circle as it should.

I don't know if this is a legitimate issue with how I set it up, or just lag time for all the changes to cache up and sync.

Will need to review this in a few days and see if the routing automagically improves, or if this still needs some love.
