The traffic in Brampton is substantially better since the widening, particularly southbound.There are no amount of lanes that will help the 410 given Brampton’s built form. I’ve lived through at least one widening and fairly soon after that it was as bad as it was before.
Brampton’s population has only increased since then, and all new developments are still heavily car-oriented.
The problem is that the widening was originally go to Bovaird, after which traffic counts on the 410 drop significantly. Instead they ended it at Queen for some unkown reason, creating a huge bottleneck northbound. Traffic counts are actually *higher* between Williams Parkway and Queen St than Queen St south to the 407.
This bottleneck causes traffic to back up to the south in the widened portion, but it only exists because of the capacity crunch between Queen St and Bovaird.
The part of the 410 south of the 407 operates traffic-free for most of the day now though, as it is far enough from that bottleneck to not really be effected, and that was absolutely not the case beforehand.
The highway would operate a lot better if they extended the 10-lane part to Bovaird, as the original plan was.
