Lebanon — Lebanon High School will be closed on Tuesday after pipes burst inside the building’s science wing, school officials announced on Monday.

Cleanup from the pipes is expected to last a day, said Tim Ball, the school district’s business administrator, in an email. He said after school activities and sporting events will go on as scheduled.

The district also announced a two-hour delay for the Mount Lebanon School, Hanover Street School and Lebanon Middle School because of projected freezing temperatures during the morning commute, according to an alert on its website.

Morning preschool is also canceled for Tuesday, but afternoon preschool will run as usual.
