A school bus carrying Dulaney High School students got stuck Wednesday morning in a sinkhole in Cockeysville, Baltimore County police said.
No students were injured in the accident at Cranbrook Road and Spring Head Court. A photo posted on Twitter by the Police Department showed the back half of the bus level with the asphalt and surrounded by water.
Baltimore County schools spokesman Mychael Dickerson said the students and the bus driver were able to get off the bus and wait for another to pick them up.
"They went on to school with a story to tell," he said.
The Police Department said a water main break caused the road to collapse. Public works crews responded to fix the break in the 12-inch main, spokesman Jeffrey Raymond said. He said water service was shut off to 150 homes and two apartment buildings while crews worked.
The break was discovered Wednesday morning, and crews had repaired the 10-foot section by Wednesday night, he said.
The cold weather has brought "a modest spike" in water main breaks, he said.
"This is the time of year where you get the overnight subfreezing temperatures and thawing," Raymond said. "If that happens where there are susceptible spots, you have pipes fail."
On Wednesday morning, he said, crews were dispatched to repair nine water main breaks in the city and three in Baltimore County, including the one in Cockeysville.
Temperatures dipped to 12 degrees early Wednesday. The cold weather forced officials in Baltimore and Baltimore County to close some schools Tuesday and sent students and faculty home early because of heating problems.
Raymond said when temperatures drop, residents should take precautions, such as making sure outside spigots are turned off and pipes drained. He said residents also should learn where the shut-off valve is at their home in case water pipes burst.
The rest of the week is expected to warm up, with highs in the 40s Thursday and Friday and in the 50s this weekend.
