Widest Highway in the world - Highway 401 Canada photos.

Though officially not the widest road in the world, this is one of the widest and great looking highways with as many as 18 lanes. The length of the highway is more than 800 km and the part of the highway passing through Toronto is the busiest and widest. It is amazing to take a look on the aerial view of the road. The highway is officially called Macdonald- Cartier Freeway.
