AVONDALE, OH (FOX19) - Traffic has been detoured around the Cincinnati Zoo while street crews continue to repair a massive sinkhole that formed last week in Avondale.
The Metropolitan Sewer District of Greater Cincinnati (MSDGC) said a safety fence was put up around the perimeter of the site, located on East Shields Street, to prevent public access to the work zone.
A Metro bus drove over the buckled area at about 9 p.m. last Thursday, causing the sinkhole to open up. No passengers were on the bus at the time, and no injuries were reported.
MSDGC said in addition to recent traffic detours, odor control is also being addressed.
Due to the depth of the sinkhole and the 16-foot diameter of the shaft, MSDGC said crews installed retaining walls and structural metal "ribs" into the area. The process makes the work difficult and slow, but is critical for safety.
MSDGC estimates repairs will likely take a month to complete, citing the extensive nature of the repair process, the depth of the collapsed pipe and need for safety precautions.
