I am surprised to find that the US has quite a number of these. Despite there being a number of them in my state, I have never traveled across the part of Diverging diamond interchange that would cause me to notice it.

Thanks for the link... I'd never heard of them before...

I've driven through one in Rochester, NY. I didn't have a chance to get out and walk it. It seemed pretty intuitive, but I'm not representative of most drivers.

I think I'll try the bike path

I'd like a word with the York and Toronto traffic light engineers about the congestion and low traffic flow from ineffective timing. Especially after 2 lanes were lost for Viva bus lanes. It is ridiculous.

With the carbon footprint, we'll have to see if private transportation keeps the current pace.

The elimination of traffic signals would seem to be a worthwhile endeavor. Nothing sillier than getting a green light to turn left off a freeway, only to be jammed up by a red light 200 ft into the new direction. Makes for a maddening drive home

...and worse, a great waste of energy and a greater carbon footprint.

There's one in Calgary, and I think one somewhere else in Canada maybe BC or Saskatchewan. It works well although was slightly confused the first time I drove up to it.

I like diverging diamonds. There's fewer conflicting movements so should be fewer collisions.

You can always try a "dog bone" interchange, with roundabouts on either side of the freeway.
