In general, the plans looked okay, and shouldn't affect too many. THey are good at building these roads - for those of you who stayed at, for instance Indian Wells, when the 417 was built - you don't notice it at all now, do you?
And if it helps traffic, and decreases the jams, then that is great!
There is conservation surrounding Sunset Lakes, so we are further away, but Emerald Isles were aware of it, and I am sure the builders will have worked that into their plan and it should not affect any homes there. [ or the other estates,of course]
