I would really like to know what was going through the heads of the designers of the 401 WB to Hurontario offramp intersection design. Turning left in the inside lane the curve is way too sharp and slows down traffic so much.
Since the left turns will often back up several signal cycles, it is faster to turn right and then do a u-turn.
Hopefully someone at the MTO sees this and can cut back the median island!
Another intersection is shown below with a more standard design that allows smooth left turns.
