The stretch of Highway 401 passing through Toronto is considered the world's busiest. The 401 is also one of the world's widest highways, stretching up to 18 lanes wide. While most of us are all too familiar with view of the 401 from behind a steering wheel, stuck in traffic, aerial photos of the highway are a rare treat. In today's Photo of the Day, which was submitted to the UrbanToronto Flickr Pool by Oscar Flores, we are given a bird's-eye view of traffic speeding (or perhaps crawling) on the 401.
