State Highway 289, known for most of its length as Preston Road, is a north–south Texas state highway. It begins at the intersection of Preston Road and Loop 12/Northwest Highway in Dallas. The Preston Road designation comes from the fact that the highway generally follows the course of an older road known as the Preston Trail, which ran to the town of Preston [Bend] . Preston is now submerged by Lake Texoma. The road is known as Preston all the way north through the remainder of the Dallas-Fort Worth Metroplex to a junction with State Highway 56 west of Sherman, near the Oklahoma state line (except for the portion through Gunter, which is designated as 8th Street). Preston Road passes through many of the fast-growing northern Dallas suburbs, including Frisco and Plano, as well as Prosper and Celina, with many new housing developments being built along Preston.
