Metro schools will remain closed Wednesday as maintenance and transportation crews work overtime to resolve mechanical issues caused by the extremely cold temperatures over the past few days.
Crews have been preparing equipment and working extended hours prior to the frigid weather to minimize its affects.
On Tuesday, transportation staff reported many school buses would not start during morning checks.
In addition to inoperable buses, maintenance crews received more than 130 calls about hear in schools, as well as numerous frozen and broken pipes.
"While weather forecasts show temperatures are warming, we have many portable classrooms that we have not been able to get enough heat to during the day and many buses that would not start this morning," said Chief Operating Officer Fred Car.
He continued, "Since staff reported today, we have also had numerous calls about frozen pipes and, as temperatures have warmed, also for broken pipes. For these reasons we made the decision to close Wednesday."
Employees will continue working extended hours to make all the needed repairs.
