The City of Toronto has been working on a plan to completely overhaul downtown Yonge Street from Queen to College/Carlton, and the recommended design was just released to the public for feedback.
The watermain beneath Yonge Street will also soon need replacing, so this construction will provide an opportunity to implement a new street design to better serve road users.
