This goes all along the timescale of these experiments. The LHC was originally introduced (ok, the idea of an LHC) in 1985-1986, built in the early 2000s and started in 2008. It is expected to run until 2035. 50 years in total.

It is clear that this kind of timescale will hold for any large-scale collider experiment. I personally hope to still be in the field when a new collider start (i.e. not retired or dead).
