Sink hole opens up in South Bend

A sinkhole formed on the 900th block of East Indiana Avenue on Monday morning. The direct cause is under investigation, but several circumstances could have played a role in its formation.

There are many different types of sink holes, but this one likely occurred due to the underground sewer infrastructure. The heavy rainfall during the prior week, and Bowman creek nearby could have possible aided in the street's demise. 

In general, a sinkhole forms when water pools up underground. The water causes the soil to loosen and wear away, forming a hole. As the hole grows bigger, there is no support for the road above, so the road collapses into the underground hole. 

It is likely that this was a growing problem that residents and city officials could not see.
