CHICAGO (CBS) — Chunks of concrete lay on the ground after falling from the wall above, from the edge of DuSable Lake Shore Drive to Randolph Street.
Falling concrete closed a street under DuSable Lake Shore Drive on Thursday and it’s not the first time CBS 2 cameras caught this problem.
Police worried the situation could get worse prompting them to close down a section of Randolph earlier. They wrapped yellow tape around fallen debris just moments after one of their officers spotted the problem.
“Things are gonna break loose. So it doesn’t surprise me at all.”
Civil engineer Mae Whiteside Williams, CEO and Founder of CKL Engineers, LLC. said the recent weather is to blame.
“Now that you finally get into these warm temperatures, you are going to find a phenomenon called concrete spalling due to the freeze-thaw cycle,” Williams said.
Williams added that if people see broken cement on the ground, to give it some space, because it’s unclear when more could fall.
