There is a similar situation on the Laurel trail in Waterloo at the intersection of Erb and Caroline. The trail north of Erb is on a diagonial to the left so cyclists have to make a left hand turn. There is a bike specific left turn lane BUT drivers coming down Caroline treat their right lane like a merge lane and cut through constantly without stopping on even on their red (This is where Erb becomes a two way street). It is not much fun southbound either. I usually find it safer and easier to take the street coming south.
