One of the grandest attractions in Grand Prairie, Texas has reached another milestone in its construction. Retractable enclosure developer OpenAire has finished installing the 40 retractable roof panels on the custom-built Epic Waters waterpark enclosure and is now completing the final sections of the unique structure. Epic Waters will cover 80,000 square feet and include a 62,000-square-foot indoor waterpark, which will be a key feature of Grand Prairie’s Grand Central park complex. The waterpark has reached two milestones in its construction so far in 2017 with the completion of the enclosure’s aluminum rafters in January and the 83-foot-high cupola in February. When it opens later this year, Epic Waters will hold the record for the largest indoor waterpark under a single custom curved retractable roof in the USA. The enormous retractable roof panels open and close at the touch of a button to let in the sun and fresh air for guests year-round, giving them a truly epic aquatic experience.
