CHICAGO (CBS) — A massive sinkhole opened up on Sunday in the Greater Grand Crossing community on the city’s South Side.

The sinkhole opened up near 73rd Street and Woodlawn Avenue.

CBS 2 is told it was the result of a cave-in on the side of a brick sewer main.

Crews from the Chicago Department of Water Management were out working Sunday afternoon in an effort to repair the road.

As of Sunday night, there was no word on what caused the sewer main to cave in.
