Hypothesis: Six-lane arterials do not belong in cities. They are inherently dangerous, uncomfortable, have a barrier effect, and antagonistic to any activity outside a motor vehicle.
Support: Walmart on H St NW going under.

@bikepedantic As a shortcut for questions like this, I just wander around Utrecht in Google Maps. My conclusion on this question is that they are acceptable in a limited area as part of offramp and onramp management of a limited access radial highway at the edges of the city. Also, this intersection is hilarious. #utrecht #engineering #safety https://www.google.com/maps/place/Utrecht,+Netherlands/@52.0796164,5.142404,131m/data=!3m1!1e3!4m6!3m5!1s0x47c66f4339d32d37:0xd6c8fc4c19af4ae9!8m2!3d52.0907374!4d5.1214201!16zL20vMGQ5czU
@bikepedantic Correct, clear safety issue
