I forgot about these; thanks for the note. It looks like that the mapper was creating separate ways for the bus. I'm pretty rusty with public transit mapping in OSM but as far as I know, since the bus lanes aren't physically separated from Euclid, what that user did should be removed. I don;t know offhand what the most appropriate tagging (on would be properly mark Euclid Avenue. I notice that the user who made these edits has been indefinitely blocked (from editing on OSM) because they hadn't responded to other users concerns on their mapping. https://www.openstreetmap.org/user_blocks/4716
