Your school probably still has the same ones. Nothing is more permanent than a temporary solution.

Strange thing in my area, since I was born, I think they've built 10 middle schools. I went to a brand new school in 8th grade, I played in the band at that school's groundbreaking. They haven't built a high school since 1975. All three of the county high schools have had additions and new wings built on campus, but they haven't built another high school since what, the Carter administration?
