Additionally, THEA owns and operates the Selmon Greenway, a multipurpose recreational pathway running beneath and alongside the Lee Roy Selmon Expressway.
THEA originally planned the neighboring Veteran's Expressway; however, Florida's Turnpike Enterprise actually built the project.
The state legislature has attempted to shut down THEA on numerous occasions during its history and transfer ownership to the Florida's Turnpike Enterprise.
The most recent attempt occurred in March, 2011 when the legislature attempted to pass a bill that would eliminate THEA, the Orlando-Orange County Expressway Authority, and Mid-Bay Bridge Authority ostensibly to save the state money.
Since its establishment, THEA has been responsible for development of numerous roadway projects in Hillsborough County.
