MILWAUKEE (CBS 58) -- The work is just beginning at the new Cristo Rey Jesuit High School on Milwaukee's south side. 

A ground-breaking celebration had students signing construction beams for the new building Wednesday.

It'll be built on 18th and National Avenue. The school opened back in 2015 as a college prep school for low-income students.

School leaders are excited for the new building.

"What this facility will enable us to do is speak to the student interests academically, provide STEM opportunities, robotics opportunities, new technologies for students to embrace and engage with," said Andrew Stith, president of Cristo Rey Jesuit High School.

Leaders hope to have the school ready for class for the 2020 school year.
