I hadn't got around to looking up the links for a story and accompanying map about the underground pedway in Sunday's Trib, but GapersBlock did the heavy lifting....
Construction of the Pedway began in the 1950s, when the portion that connects the CTA's Red and Blue Lines was built under Washington Street. The last section to be built, to the Monroe Street Garage, was added in the mid-1990s.The 25 structures linked by the pedway reads likes a "Who's Who" of Chicago buildings: The Richard J. Daley Center, the State of Illinois Center, the Dirksen Federal Building, the Palmer House Hilton, the Randolph Street Metra Station, Marshall Field's, Carson Pirie Scott, Doral Plaza, the Aon Center, the Leo Burnett Building, the Fairmont Hotel and the Chicago Cultural Center.
From the beginning, "the intent of the pedway was to provide an enclosed pathway that people could use in the winter," Steele said.
And that hasn't changed, though the route is open year-round.
The latest development was the reconstruction of a half-block section between Wabash Street and the Chicago Cultural Center on Michigan Avenue in December. The renovation was done to go along with a new 57-story residential tower, The Heritage of Millennium Park, on Randolph Street.
Pedway hours vary. But basically it is open between 6 a.m. and 6 p.m., Steele said. Pedway access usually is from the basements of the buildings on it."It's a bit of an undiscovered gem in the city," said Steele.
for a while, the article (and map link) is here. I saved the dead trees edition, so plan to scan the map, eventually.
