Columbia Chronicle -- “In a lot of [Chicago] downtown and in a lot of the neighborhoods throughout the city, we have what we call ‘vaulted sidewalks,’” Steele said. “Underneath the sidewalks is an open space, an open vault. They date back to the turn of the century when the city was raised up a level. Not all of it is empty space, but some of it is.”

Crews are working on filling empty vaulted sidewalks with concrete to give them more structural support and reduce the number of future repairs, Steele said.
