Step treks

By Virginia Linn / Pittsburgh Post-Gazette

With 739 sets of steps, Pittsburgh has more municipal stairways than any city in the U.S.. That’s according to Bob Regan, author of his updated “Pittsburgh Steps” (2015), which is part historical record and part guidebook for active step trekkers. Of these stairways, 344 are legal streets — composed just of steps.
