Chisholm Trail Parkway is a toll road planned to be operated by the North Texas Tollway Authority (NTTA) in Tarrant and Johnson counties connecting the central business district of the city of Fort Worth at I-30 to US 67 in Cleburne.
The project is proposed to be constructed as a 27.6-mile (44.4 km), controlled-access, four- to six-lane divided toll road along the route of an extension of State Highway 121. Environmental clearance for the project was received in June 2005. Initial construction began in April 2010. Chisholm Trail Parkway is tentatively scheduled to be open to traffic in early 2014. The NTTA's consulting engineers have estimated that the cost of the Chisholm Trail Parkway will be approximately $1.4 billion.
The segment of the parkway from FM 1187 to I-30 in Tarrant County was originally named Southwest Parkway. Legislation renaming that segment was passed in May 2011.[1]
