Construction on Round Hill Elementary will finish up in the early Fall.
School officials say the project is right on time and they told parents at the end of school last year that there may be some overlap.
This is the second phase of three major upgrades to the school.
This phase costs $4.7 million, it includes building a new kitchen and cafeteria as well as expanded classroom space.
Roanoke City Schools Superintendent Rita Bishop says the ball is rolling at Round Hill Elementary School.
Construction crews will be working all summer to finish the nearly $4.7 million second part of a three-part expansion.
Two years ago, the school had around 100 more students show up on day one than they were anticipating.
School leaders say Round Hill has been the school that's most prone to dramatic enrollment swings.
The hope is to finish construction in the fall, but as superintendent Rita Bishop says, unforseen things can happen.
"It depends on weather, we're certainly going to have it as soon as we can get it. Building a cafeteria and six classrooms is a large undertaking. I'm big on, I'd rather over deliver and under promise," Dr. Bishop said.
School leaders say the new kitchen for the school will be bigger than the entire old cafeteria.
The way the current renovations will work will enable even more growth, even more classrooms if the school continues to grow as rapidly.
