LOUISVILLE, Ky. (WDRB) -- A section of I-265 East in Floyd County is back open after a sinkhole closed all lanes for 12 hours.

The sinkhole opened on I-265 East between the Charlestown Road exit and I-65 late Tuesday night, according to Indiana State Police. All lanes of I-265 were immediately closed with traffic being diverted off at the Charlestown Road exit.

Indiana Department of Transportation spokesman Natalie Garrett said crews from MAC Construction had to use heavy equipment to rip up the asphalt and open up the hole to make repairs to both eastbound lanes of I-65. The sinkhole was 24 feet wide, 30 feet long and 15 feet deep. 

"It didn't start that big, of course, but they made it bigger so that they could do a uniform repair across both lanes," Garrett said. 

The sinkhole was filled with gravel and paved over, and all eastbound lanes of the interstate reopened around 8 p.m. Wednesday. 

Some question if all that heavy material could make the sinkhole even deeper. 

"They've been testing along the way as they're filling,  just to try to avoid that issue.," Garrett said. "And they'll do a final inspection when everything is repaired."

Westbound lanes were also inspected.

The newly patched portion of the interstate will be monitored for the time being to make sure the new pavement isn't sinking. 

"We'll be watching that, and we'll do additional repairs if necessary," Garrett said.

Early Wednesday, two people were killed in the backup caused by the sinkhole on I-265 East near the Grant Line Road exit.
