The intersection at Ohio and Pennsylvania streets in downtown Indianapolis has been closed since July 4 when a sinkhole opened.

Normally, about 40,000 vehicles travel through the intersection of Ohio and Pennsylvania streets every day. Drivers are being detoured onto adjacent streets.

Citizens Energy Group says the sinkhole that opened in downtown Indianapolis Wednesday was caused by the failure of a century-old sewer line.

The road closure will be the result of work to complete a section of the Dig Indy tunnel project.

With 3.5 inches of rain over the past 24 hours, Citizens says about 700 million gallons of raw sewage overflowed from Marion County's combined sewer system.

A temporary change in the type of chlorine Citizens Energy Group uses to treat our water supply will be made Friday, Jan. 27.

Ross Claypool park reopened on the west side of Indianapolis after nine months of underground tunnel construction. Features include a new basketball court and rain garden.

More than 100 of Indiana's sewage systems need improvements to comply with federal standards, and the Environmental Protection Agency has sued many cities and towns over sewage overflow problems. Some cities are building new sewage overflow tunnels to fix the problem.

Citizens Energy Group says some customers may notice a temporary chlorine or "swimming pool" smell in their water; but the utility company says the tap water is still safe to drink and meets all regulatory requirements.
