I know that Seattle converted at least one tunnel, which was originally
to be for a light rail line, into a dedicated bus lane.

I've not seen, however, anything like this.

The problem with a Holborn-Aldwych cycle route is that unless the
Holborn end is for Piccadilly Line passengers, the round trip
surface-tube-surface will take longer than walking. And don't let us
forget one the main reasons Aldwych closed was it was too expensive to
repair the lifts. Finally, what about the tidal flow of Boris-bikes -
what tooth fairy is going to be shuttling them back to the other end so
that more than a couple of dozen people can use the route each morning
or evening?
