It would be nice if they eventually reoriented the southern portion to a cycle track, seems to me it would help the wrong way biker problem I've seen in the bike lanes. I would assume you would do the same thing you do when you are turning left onto Marshall. A special light would be nice, but I would do one of two things depending on traffic: 1. Transfer into the car lanes and use the normal signals. 2. Pull into the crosswalk and follow the pedestrian signals.
I do think they are doing work on the lights there, so a special light may be coming.
