You say “and/or”; but if there isn’t a ramp, an elevator would be needed. An escalator is very convenient for many but just doesn’t do the job for everybody, in particular for people in wheelchairs.
What I really meant was "elevator plus possibly an escalator".
I understand you like tunnels, but my question was about the option of using stairs+elevator (+possibly escalator) instead of a ramp, for a bridge.
