Construction of a new career and technology education site is underway. This project is the reason for the closure of Sunnyside park. The closure occurred sooner than expected to allow for the construction to begin.

The city's parks and recreation department provided this information. They stated that Houston ISD ended the park's use early to start the construction project.

Further details about the closure and construction project are available from the source. The new education site is intended to support career and technology education.
