Steaming temperatures Monday were responsible for pavement buckling on the Lake Shore Drive roadway, city officials said.



Chicago Department of Transportation officials were notified that at about 4:30 p.m. the roadway began buckling on the Southbound Lake Shore Drive just north of 31st street, said Michael Claffey, a spokesman for the city agency. Officials said the high temperatures were responsible for the pavement buckling.



Workers were able to get to 31st Street and began making repairs which were expected to conclude at 7:30 p.m. During the repairs a single lane of traffic was able to get by, said Claffey.



As workers were concluding work on the first incident, more buckling was reported on the Northbound lanes near 39th Street. Crews were on their way there as of 7:30 p.m. and lanes were reopened by 8:30 p.m., said Claffey.
