Calgary has an instance of triple left-turn lanes located downtown, with certain lanes guiding you toward very specific (and divergent) destinations/directions within a very short distance! If you're familiar with the roads/intersections, you just have to be careful to select your driving lane strategically, esp. during rush hour(s) or you may end up needing to reroute (Good thing for GPS!
) I think the locals do ok to navigate, even after the winter wear!
Looking forward to see this project in its entirety!
