It's uncertain how long Warren Street in Phillipsburg will be closed because of a water main break.
Some Phillipsburg residents didn't have water Friday morning and some students have a delayed start of school due to a main break about 2:30 a.m. on Warren Street.
The break was at the bottom of the street near the railroad bridge, Mayor Stephen Ellis said, and the road was closed to Center Street.
"The school opening is dependent upon which pipe is broken: large or small main," Ellis said in a text.
The school district said Phillipsburg Primary School and the Early Childhood Learning Center were on a two-hour delay. The old middle school, now Phillipsburg Elementary, was open, Ellis said.
School district Superintendent George Chando said a decision would be made by 8:45 whether school can open. Both buildings are affected by the break, he said. Ellis and Chando later said the schools indeed would open on a two-hour delay.
The primary school and kindergarten at the learning center will have an arrival time of 10 a.m.; preschool at the learning center will be 10:15 a.m., Chando said.
When school opens, students should walk on the right side of Warren Street "on the site of old Keystone Packaging," Ellis said.
The break was reported at 2:48 a.m. at 599 Warren St., according to the Warren County Department of Public Safety.
It wasn't immediately clear how many customers were affected or when service might be restored. Ellis said if it was a small main the repair could be relatively quick, but a large main break could close the street all day.
He later said the initial break was fixed but a second break was found and that also was fixed.
A spokeswoman for Aqua New Jersey couldn't immediately be reached.
