A large portion of Southwest Trafficway in Kansas City will remain closed into next week after officials said a sewer from 1892 collapsed under the roadway.

Lanes of Southwest Trafficway were closed earlier this week following a partial street collapse.

Kansas City police said they were called out around 1:45 p.m. Wednesday after a sinkhole was reported in the southbound lanes near 31st Street.

KC Water said crews are addressing the collapse, which was reported between 28th and 31st streets.

Officials said in a news conference Friday that a clay sewer from 1892 collapsed under the roadway, causing the massive sinkhole. The issue is approximately 25 feet underground.

Complicating matters are a nearby waterline dating back to 1932, along with underground lines from Evergy.

As a result of that sewer collapse, crews expect to have to rip up approximately 80 feet of roadway.

They are anticipating that portion of Southwest Trafficway will remain closed through 6 a.m. Wednesday at the earliest.

Drivers who normally travel through the area should find an alternate route.
