MIAMI, July 26 /PRNewswire/ -- MasTec, Inc. (NYSE: MTZ) announced today that it has been selected as the exclusive end-to-end fiber optic network engineering and installation service provider for a fiber optic network along 2,200 miles of Florida's Turnpike and interstate highways.

MasTec will provide infrastructure services for the multi-year project to Florida Fiber Networks, Inc. The planned network will be the nation's largest public/private fiber optic network. Florida Fiber Networks will deploy the fiber network along major limited access highways such as I-95, I-75, I-10, I- 4, and Florida's Turnpike.
