WATCH: Massive Sinkhole Nearly Swallows Two Homes in Montgomery County: Reports

A massive sinkhole opened up in the Glenside section of Cheltenham Township on Wednesday morning, nearly swallowing a home completely, according to multiple media reports.

6ABC reports that a pickup truck is teetering on the edge of the hole and that residents from the surrounding neighborhood have been evacuated.

The hole, on the 700 block of Brooke Road, covers a swath of the yards immediately in front of two homes.

It may have been caused by a six-inch water main break that has left up to 40 homes without water, according to Aqua America. Customers will likely be without water service for the rest of the day.

It is not yet clear if the sinkhole was caused by the break, or the sinkhole led to the break, or if some other factor was involved, authorities said.

Two homes affected by the sinkhole are now uninhabitable, Fox29 reports.

Brooke Road has been shut down between West Chelfield and Argyle Roads, Montgomery County Active Incidents states.

The sinkhole first opened up just before 4 a.m. Wednesday morning, according to NBC 10.

No injuries have been reported.
