ROANOKE COUNTY, Va. -

Glenvar High School kicked off its major renovation project on Tuesday evening with an official ceremony.

The community came out to hear school leaders speak about the project.

Construction can already be seen outside of the school but now major work will begin.

The plan is to fix the outside, build a new library, cafeteria, restrooms, a science wing, and even a new electrical system.

School Board Chairman David Wymer says the school is celebrating a special milestone. "This school, when we get back in it, will be celebrating its 50th anniversary. During that time there have been some cosmetic renovations but nothing like what we're talking about here."

During construction students will have classes inside trailers and in parts of the school.

Total cost of the renovations will be around twenty-eight million dollars.

School leaders say the project should be complete by the fall of 2015.
