@shifter I generally agree that underpasses are better than overpasses on a bike in a city; except when you on a bike is forced to pass a 90° bend down at the bottom, or you have to stop at a crossing of bike lanes.

@shifter It's obviously much cheaper to build a bridge that only has to accommodate two lanes of bicycle and pedestrian traffic than it is to build a bridge that has to accommodate 6-8 lanes or more of highway traffic.

IMO best way would be to create underpass for cars. That way pedestrians and cyclists don't have to change elevation at all. I live in hilly area and it is pretty common to build roads (highways especially) and railroads into the terrain and leave streets and crossings of those somewhat elevation neutral.
