On Monday morning, city crews discovered a large sinkhole in the 900 block of E. Herring Avenue.
The 15 to 20 feet deep sinkhole shut down the westbound lane of E. Herring between J.J. Flewellen and Dan Rowe
According to the Water Utilities Public Relations Coordinator Jonathan Echols, the collapse of a 24-inch Waco Metropolitan Regional Sewerage System sanitary sewer main may have caused the sinkhole.
Echols said the rain could be a contributing factor to the sinkhole. Crews will wait until the rain subsides and the ground is dry to determine the cause of the sinkhole.
Westbound Herring Ave., from J.J. Flewellen Rd. to Dallas Street will remain closed until the repairs are complete, which could take, at least, three to four weeks.
A detour has been set up using Dallas St. and Faulkner Ln.
This sinkhole is the third one in that general area in the past 18 months, according to Echols. One developed on Herring Avenue and MLK Jr. Blvd in July and the other one happened a block from that location.
The 24-inch sewer main that may have been affected this time feeds into a line that collapsed when a sinkhole developed on Herring Ave. and MLK Jr. Blvd in July.
No sewage was released to the surrounding area and water pressure is not expected to be affected, according to Echols.
