Seemed logical as it was a bridge over an interstate, so to make it easier for entrance/exit ramps. Still wonder how many accidents happened there the first month it was open.
I think people find them weird when viewed from above, but when you're going through them there isn't that much to them. If you're in the SF Bay Area and want to try one out, there's one in Manteca, a little more than an hour away.
Might it be deliberate? I imagine a lot of drivers might be spooked to see "wrong" traffic, especially if it's headlights at night and they can't quite see the layout.
