Road design, transportation and walkability

[WLU]

If you look at the 401 through Toronto, the traffic on that road is saturated. It has had roughly the same volume of traffic for well over a decade despite the fact that Toronto has grown significantly over the same period of time. Why do you think that is?

The best example is I-405 Sepelveda pass in LA. Over a billion was spent to widen this world renowned traffic jam. Within only a few years traffic speeds are now below where they were before widening. A billion spent to make things worse, what a failure.

I gave you an example of a local project where $20 million was spent on the expressway locally with successful results.  Why compare it to a $1 billion dollar project in L.A.?  Additionally, if you look hard enough you'll find bust in all kinds of projects roads, public utilities, transit etc.
