CINCINNATI -- The sinkhole that nearly swallowed a Metro bus will swallow a lot of money.
The repair will cost about $300,000 and take a few more weeks, the Metropolitan Sewer District told 9 on Your Side Wednesday.

The 101-year old sewer line deteriorated and gave way on East Shields Street, near Vine Street, in University Heights on June 19.
That created a sinkhole that collapsed when a Metro bus passed over it. The driver was the only person on the bus when the road caved in, trapping the back of the bus. She was not hurt.
The sinkhole spread about 15 feet long and wide and 20 feet deep. Once the bus was removed that day, MSD crews went to work to remove collapsed concrete, raw sewage and broken sewer pipes.
Crews expect to wrap up repairs by the middle of the month, but they say it's not easy.
They're using robotic cameras to find the broken pipe, but otherwise they're mostly using their hands, dealing with sewage from nearby hospitals and enduring thousands of cockroaches.
