Please be advised that the Mountainside Public Library will be closed beginning Monday, September 7, 2026, through 9:30AM on Monday, September 21, 2026, due to the start of the Library Roof Replacement Project.

The Library is scheduled to reopen at 9:30AM on Monday, September 21, 2026.

This temporary closure is necessary to ensure the safety of the public while the initial phase of roof construction is underway.
