State Highway(SH) 360 connects Mansfield, Grand Prairie and Arlington to I-20, I30, SH183 east/west corridors in Tarrant and Dallas Counties, and US 287 in Ellis County. A combined population of 1.8 million people in Tarrant County would be served with improved accessibility throughout these areas. SH161 is the only other north/south facility that serves the Metroplex between I-35E in Dallas and I-35W in Fort Worth. Not only does SH360 provide direct access to DFW Airport for residents and major employers, it also provides regional access to some rapidly growing development zones including the Great Southwest Industrial District, the Arlington Entertainment District, the University of Texas at Arlington, Tarrant County College Southeast Campus, the recently opened Grand Prairie Premium Outlet Mall, and downtown Arlington.
The Texas Department of Transportation (TxDOT) initiated the State Highway (SH) 360 corridor study, conducted preliminary studies, processed environmental reviews, obtained environmental clearance and right of way from south of Interstate 20 to U.S. 287 and built the existing roadway.
In 2014, the NTTA Board of Directors and the Texas Transportation Commission entered into a Memorandum of Understanding (MOU) to deliver the 360 Tollway (formerly SH 360 South project) as a public-public partnership. Under the terms of the MOU, TxDOT will finance and build the project, while the NTTA will own, operate and maintain the project once construction is complete.
In February 2014, the NTTA Board of Directors approved agreements with the Regional Transportation Council (RTC) and TxDOT to develop, finance and construct 360 Tollway.
The 360 Tollway project will be built in two phases, an initial and an ultimate. Funding is not currently available for the ultimate.
In July 2017, the NTTA Board of Directors selected “360 Tollway” as the official name of the road. 360 Tollway is a 9.7-mile project from Green Oaks Boulevard to U.S. 287 which includes the expansion of the SH 360 main lanes from Sublett Road/Camp Wisdom Road in southern Tarrant County to U.S. 287 in northwestern Ellis County and northeastern Johnson County.
The Texas Legislature passed and Governor Greg Abbott signed into law legislation designating two portions of the 360 Tollway in memory of a civil rights icon and a long-term legislative leader from Arlington. The designations, effective Sept. 1, 2017, are as follows:
- Rosa Parks Memorial Parkway from the municipal limits of Mansﬁeld to its intersection with East Sublett Road/West Camp Wisdom Road in Tarrant County
- Senator Chris Harris Memorial Highway from the intersection with U.S. 287 in Ellis County to the municipal limits of Mansﬁeld in Tarrant County
