MOORE, Oklahoma - Moore High School recently celebrated the completion of a tornado storm shelter on their campus.

City and school district leaders in Moore will ultimately like to see storm shelters in every school in the district.

Moore High School's new shelter can comfortably fit 2,600 people, which is enough for the entire student and staff population at the school.

The addition comes with new classrooms, bathrooms and a choir room.

Moore Public Schools helped pay for the improvements with a $209 million bond issue, the largest in district history.

Many of the changes the money will be used for are a direct result of the May 2013 tornado that damaged several schools and destroyed both Briarwood Elementary and Plaza Towers Elementary.

"It really gives me a peace of mind, of course. In Moore, with some of the tragedies we've faced with tornadoes coming to our district, that I can get every student and every adult on campus in this shelter. It's actually a break away shelter, so we shut the doors, and if something were to happen, that building would remain standing, so it's a huge peace of mind," Moore High School sophomore principal Brandi Brickman said.

Moore High School administrators have already held a couple of tornado drills this year and said they can get the entire school safely in the shelter in just under 20 minutes.
