The constant changes to Don Mills/Eglinton have also been a bit chaotic. Lanes seem to shift on a weekly basis, with little to no changes made to the pavement marking or signage. I have already seen two pretty bad accidents in the past few weeks where cars have pretty much hit head on because the lane markings didn't exist.
The middle lanes sometimes seem to lead into the opposing lane from the other direction, or lanes simply end with no warning, forcing last minute lane changes. There was also a few days of the middle lane disappearing mid-intersection, forcing cars to suddenly change lanes illegally and at the last minute, in the middle of the intersection. Absolutely no signage or warning, and impossible to see from afar as the jog in Don Mills now directs you to the right before reaching the intersection. The contractor needs to do better at managing traffic flow. I don't think they are even trying at this point.
