The problem with using the old streetcar tunnel as a pedway is how unrelievedly boring it is. It's one thing to walk 1000 feet on a sidewalk, past shop windows and intervening streets, but an entirely different thing to walk that far in a lonely underground tunnel. For anyone to ever use it—except when it's below 0º—you'd have to put in a little shuttle, like the Senate Subway or Denver airport. Maybe we could put some electric scooters at both ends.
