Superintendent Reginald Lawrence says the building now has a more secure entrance, more cameras throughout the building, and all the major offices are now in one location.
"But oftentimes when you had to get to our main office, or you had to get to the nurse's office, or you had to get to the suite to talk to assistant principals and such, you pretty much had to trek halfway through our building."
In addition, Rock Island High School now has a new, and larger cafeteria.
"We needed more space for students who are sometimes in our buildings from 6 am to 9 or 10 o'clock at night. So with the college commons area that has some flexible seating, it has charging spaces for students, and it gives them somewhere to be both before school and after school."
Money for the renovation was provided by the local option sales tax for schools. Doctor Lawrence says this and other building projects in the district follow years of deferred maintenance, and few if any upgrades to the schools.
A ribbon cutting ceremony will be held at 4 pm Monday.
