That hasn't been the case in Phoenix where we're building lots of freeways and expanding existing ones. In fact, the latest two light fail expansions have caused numerous business failures due to street closures and restrictions and the whole system clogs traffic on the streets it runs along.
I think the funniest one is they're expanding one section across I 17 at about Dunlap Rd., and it's going into a now abandoned mall (Metrocenter).
That's the route at the top of the map.
The light green one marked "South Central" runs along a street with nothing but industrial, wholesale, and other businesses that don't do foot traffic at all--ZERO. One of the vendors I use regularly is just off that street. There's nothing down there for passenger service. No residential anywhere, no businesses that work on foot traffic. So, that leg is going to be a huge fail for passenger service.
