Hi all,
Latest report from SFMTA is that the D/B intersection should be done by end of July. The lane markings you see now are where the lanes will actually be, but probably with nicer, clearer paint.
Please see the June 19 blog update regarding the feasibility (or not) of simultaneous protected left-hand turns or protected left-hand turns that change according to rush hour conditions.
