What engineering challenges exist in elevated theme park designs?

The source provided is the Wikipedia entry for Jurassic Park, a 1993 science‑fiction film. It contains no discussion of theme‑park infrastructure, civil or structural engineering, or the design of elevated attractions. Consequently, based solely on the provided evidence, we cannot identify any engineering challenges related to elevated theme‑park designs. You would need additional sources that specifically address theme‑park engineering to obtain that information.
