A few months ago, I blogged about the flights of stairs leading up from Sheridan Hollow. Pictured above is the unused flight leading up to a weed-covered gate near the Erastus Palmer house on Columbia Place.
Very near this set of crumbling steps was the old Hawk Street viaduct. This pedestrian bridge, considered an engineering marvel when it was completed around 1890, spanned a thousand feet over Sheridan Hollow to connect the neighborhoods around the Capitol to the northern part of the City.
The viaduct is long gone. I've only seen it in photos on old postcards. As of the early 90s, a small remnant of the south abutment was supposedly visible near these stairs. Even that seems to have vanished, apparently beneath the parking garage.
