State Highway 81 (SH 81) is a Texas state highway that runs from Hillsboro to Grandview. It was designated in 1991 to replace U.S. Highway 81, which was decommissioned south of Fort Worth.
SH 81 begins along the ramp from northbound I-35's exit #364B; the route is accessible from the southbound freeway at exit #364A for FM 310. It travels north into Hillsboro along Abbott Avenue. SH 81 has a half-mile concurrency with SH 22 / SH 171 through the city's downtown before continuing northward along Waco Street. At the northern edge of Hillsboro, the highway has an interchange with Spur 579, which provides access to Interstate 35, as well as US 77, just south of the point at which the freeway splits into I-35W and I-35E.
North of Hillsboro, SH 81 roughly parallels I-35W, which lies to the east. While the freeway bypasses the cities of Itasca and Grandview, SH 81 enters them directly, along Hill Street and 3rd Street, respectively. In Grandview, it intersects FM 916 and also FM 4 at that route's southern terminus before continuing northward to its end at I-35W's exit #16; the roadway continues as County Road 201A.
