Chicago police and fire responded Tuesday afternoon to a partial building collapse at a Morton Salt storage facility on 1301 N. Elston Avenue.
A wall of the building collapsed, and a mountain of salt poured onto several nearby vehicles.
Fire officials said workers at the storage facility apparently piled the salt higher than they were supposed to, and the resulting pressure caused the south wall to cave.
The building was last inspected by the city in March of 2014. It has an outstanding violation for failure to maintain the roof in sound condition.
There were no reported injuries. The salt buried at least 11 cars at the neighboring McGrath Acura dealership. Some of the cars were new, others belonged to people who dropped them off to have them serviced.
Officials are now trying to determine how to remove the salt safely.
