For one of Toronto's most important streets (if not the most important street), Yonge sucks for pedestrians and cyclists.
The sidewalks are narrow at points, there are no bike lanes, and the public realm is quite "bleh." Save for construction scaffolding and a smattering of bike rings, there's little streetscaping at all along Yonge Street throughout the downtown core.
