This seems like it should work. I was a little wary at first, since wiki for Key:lanes states "Count excludes cycle lanes. For tagging cycle lanes see cycleway=*. " However the example in https://wiki.openstreetmap.org/wiki/Lanes#Crossing_with_a_designated_lane_for_bicycles seems fitting, and the following seems to be liked well enough by JOSM validator: https://bin.piorkowski.ca/2020/osm_bicycle_lanes_on_way.png access:lanes:forward=||no bicycle:lanes:forward=||designated cycleway:lanes:forward=none|none|lane cycleway=lane turn:lanes:forward=left|none|left Trying to go further and indicate also the through-going (painted) bicycle lane (as done in the wiki example linked above) I arrive at: https://bin.piorkowski.ca/2020/osm_bicycle_lanes_on_way_with_cycle_lane.png access:lanes:forward=||no|no bicycle:lanes:forward=||designated|designated cycleway:lanes:forward=none|none|lane|lane cycleway=lane (redundant?) lanes:bicycle:forward=2 turn:lanes:forward=left|none|none|left That seems to describe the logic of the way fully. However that is quite a lot of tags and seems easy to get it wrong. JOSM will warn in case of mismatch, but it's not exactly straightforward... hm... Thanks! --Jarek
