Try the lanes extension tagging:

Assuming that it's mapped as two one-way ways and there are two through 
car lanes at the point where the hook turn is (can't tell from the photo 
if there is a turning lane for cars):

lanes=2                <--- lanes only counts lanes wide enough for cars
turn:lanes=right|through|through|through
cycleway:lanes=lane|lane|none|none
access:lanes=no|no||     <--- over rides the default access with no for 
the two bicycle lanes
bicycle:lanes=designated|designated||  <--- set the access for bicycles
