IDOT on Wednesday was urging Chicago drivers to avoid downtown expressways for at least 24 hours after after pavement buckled on the westbound Kennedy Expressway at Adams Street.
UPDATE: According to the Tribune’s Jon Hilkevitch, the expressway’s pavement buckled near Adams Street when concrete grout flowed through a crack in a repaired section of the Quincy freight tunnel wall and pushed upward to the Kennedy lanes.
The Illinois Department of Transportation said the construction company that was pumping the concrete into the unused freight tunnel will not be held responsible for damaging two lanes of the highway, according to Hilkevitch’s article.
The emergency repairs cost more than $70,000.
