Hello MountSuckling, in this changeset you have disconnect the 301-2 street from the main road. on the ground it is connected and open. I assume you only looked for the sat image and thought that maybe it's closed, but that sat image is old, it doesn't have the passing bridge too if you looked. I just fixed this changeset and reconnect the street to the main road in https://www.openstreetmap.org/changeset/148463695.    
Regards.
