The National Gypsum Wallboard Plant at Apollo Beach, Florida, is a 424,000 square feet wallboard manufacturing facility on a 130-acre site. Most wallboard manufacturing plants use gypsum rock; however, this location uses byproduct gypsum produced by Tampa Electric when it scrubs its sulfur dioxide emissions. The project was extensive and included support for the construction of five new turn lanes on US 41, the re-construction of Pembroke Road and Wyandotte Road, one new rail crossing, and the re-construction of one rail crossing, half mile of off-site utility extensions, one half mile of roadway drainage improvements, 6-acre container storage lot with rail spur (4 lines), 190,000 sf warehouse, high volume gypsum unloading, and storage facility with truck/wheel wash facility.
