State Highway 360 (SH 360) is a north–south state highway in the Dallas–Fort Worth metroplex in the U.S. state of Texas. It runs north from an at-grade intersection with US 287 in Mansfield, near the Ellis-Johnson county line to a partial interchange with SH 121 in Grapevine, near Dallas/Fort Worth International Airport. The highway serves as a local north–south route running through the center of the metroplex, linking together the southern and northern suburbs to the core. Between US 287 and Camp Wisdom Road/Sublett Road, SH 360 follows a pair of frontage roads along a four-lane tollway known as the 360 Tollway, a tollway operated by the NTTA. Between Camp Wisdom Road/Sublett Road and SH 121, SH 360 follows a toll-free freeway maintained by TxDOT. The highway was opened in several stages throughout its existence. The first portion of the highway was designated on November 30, 1955, between US 80 (now SH 180) and SH 183. Newer portions of the highway were opened between 1960 and 2003. The 360 Tollway was opened in 2018, and is eventually planned to extend southward to a terminus at US 67 in Venus. Route description SH 360 begins as a pair of frontage roads at its southern terminus at an at-grade intersection with US 287 in Mansfield, near the Ellis-Johnson county line. North of its intersection with US 287, SH 360 expands into a pair of free two-lane frontage roads along a four-lane toll road, the 360 Tollway, which continues north for . In southwest Grand Prairie, SH 360 becomes a toll-free freeway at an intersection with Sublett Road/Camp Wisdom Road. From there, the freeway proceeds north through Arlington near its boundary with Grand Prairie, where it interchanges with I-20 and then meets I-30. However, SH 360 and I-30 are not directly connected. As a legacy of the original toll road design of I-30 (formerly the Dallas-Fort Worth Turnpike), the highways connect only indirectly using long access roads that cross surface streets at lighted intersections. From I-30, SH 360 then continues north beyond Arlington, interchanging with SH 183 near Euless. From the SH 183 interchange, the freeway continues north-northwest through Euless and into Grapevine, following the western boundary of Dallas/Fort Worth International Airport. SH 360 terminates at its northern terminus at a partial interchange with SH 121 in Grapevine. History SH 360 was constructed in different stages over the course of several decades. SH
