(MONROE COUNTY) - As I-69 construction continues in Monroe County, crews are encountering a number of sinkholes some 30-feet deep and 15-feet across.
INDOT says this was not unexpected given all the karst features in the area.
I-69 opponent Thomas Tokarski says building the interstate over these sinkholes poses a threat to the groundwater because pollutants and runoff can seep through openings and into the water table.
INDOT spokesperson Will Wingfield says the department has taken precautions so that does not happen.
The section of I-69 from Crane to State Road 37 just south of Bloomington is expected to be complete by the end of 2014.
