According to the City of Chicago, the northbound lanes of traffic are now open on Lake Shore Drive.
The lanes were closed mid-day Monday after Chicago Department of Transportation employees noticed two cracked girders on Lake Shore Drive and another cracked girder on a ramp from Wacker to south Lake Shore Drive. The closure lasted just over a day. Since the problem was discovered, CDOT workers worked nonstop to repair the street.
Susan Hofer, a CDOT spokesperson, said the work went well over the 24-hour period.
“We made good progress through the night,” she said in an email Tuesday. “We re-opened The Wacker to southbound Lake Shore Drive ramp last night.”
At an on-site press conference with CDOT Commissioner Rebekah Scheinfeld, she explained the cracked beams were bolstered with four shoring towers.
“This will allow us to make repairs,” she explained. “We expect permanent repairs will be done over the next several weeks.”
The shoring towers can withstand a total of 300,000 pounds of pressure each.
The total cost of the temporary and permanent fix isn’t yet known.
Hofer added that CDOT is still not sure what exactly led to the cracks, though the polar vortex might have been a factor.
“We think the extreme temp variations might be part of the problem,” she said. “We’re still working on determining the causes.
CDOT engineers are continuing to inspect other girders throughout the road system for cracks.
