Wouldn't the space and extra travel distance required for above-street ramps makes them impractical? If you want to rise 15 ft in the air at a 5% grade, you need 300 ft. Now imagine a ramp every block.
- bluGill 7y agoThat depends, is there are network of them such that you can go a few km without going outside, or is it across one road. The latter is worthless for all the reasons you mention. For dense areas (downtown) they are fairly common, office workers can go several buildings over to lunch without going outside, and things are heated in winter.
- CydeWeys 7y agoThey're fairly common? Can you provide examples? The closest thing I can think of is a series of connected pedestrian tunnels that you see in some Canadian cities like Montreal and Toronto. Those primarily exist for a different reason; winter is months-long and so cold that you don't want to step foot outside at all. Pedestrian bridges don't accomplish this goal.

- CydeWeys 7y agoHow old is the skyway system? Were the buildings built with this in mind or were they added on later?
