The Chisholm Trail was a trail used in the post-Civil War era to drive cattle overland from ranches in southern Texas, crossed the Red River into Indian Territory, and ended at Kansas rail stops. The trail encompassed a pathway established by Black Beaver in 1861, and a wagon road established by Jesse Chisholm around 1864. "The Chisholm Wagon Road went from Chisholm's trading post on the South Canadian (north of Fort Arbuckle to the Cimarron River crossing, to the Arkansas River at the future site of Wichita where Chisholm had another trading post and on north to Abilene," according to the Kraisingers. By 1869, the entire trail from Texas to Kansas became known as the Chisholm Trail.
State Highway 360 is a 28-mile (45 km) north–south freeway 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.
State Highway 99, also known as the Grand Parkway, is a beltway in the U.S. state of Texas. Its first section opened on August 31, 1994. When the route is completed, it will be the longest beltway in the U.S., the world's seventh-longest ring road, and the third (outer) loop of the Houston–The Woodlands–Sugar Land metropolitan area, with Interstate 610 being the first (inner) loop and Beltway 8 being the second (middle) loop. The proposed 170-mile (270 km) loop has been divided into 11 separate segments for construction and funding purposes. In May 2019, the Texas Department of Transportation gave the Grand Parkway a secondary designation as the Mayor Bob Lanier Memorial Parkway, honoring Bob Lanier, who served as the mayor of Houston from 1992 to 1998 and who had spearheaded the creation of the Grand Parkway.
Beltway 8 (BW8), the Sam Houston Parkway, along with the Sam Houston Tollway, is an 88-mile (142 km) beltway around the city of Houston, Texas, United States, lying entirely within Harris County.
The President George Bush Turnpike (PGBT) is a 52-mile (84 km) controlled-access toll road running through the northern, northeastern and western suburbs, forming a partial beltway around Dallas, Texas, United States. It is named for the late George H. W. Bush, the 41st president of the United States. At its west end near Belt Line Road in Irving, State Highway 161 continues southwest to I-20 in Grand Prairie. The discontinuous free frontage roads along the turnpike from I-35E in Carrollton east to its end at I-30 in Garland are assigned the State Highway 190 designation. SH 190 signage appears only along the Rowlett, Garland, Richardson, Plano, and Carrollton sections of the frontage road with the undersign "frontage road only". At intersections with city streets, only the Bush Turnpike signs are displayed, not the SH 190 signage. Prior to the construction of the main lanes as a tollway, SH 190 was used as the name of the planned main lanes too. Similarly, the part west of I-35E was planned as part of SH 161. Bush Turnpike is signed as a north–south road from I-20 to I-35E, an east–west road from I-35E to the Merritt Main Lane Gantry and as a north–south road from the Merritt Main Lane Gantry to I-30, as Bush Turnpike makes a nearly 90-degree curve in both places.
State Highway 183 is a state highway in the Dallas–Fort Worth metroplex in Texas. Its most heavily used section is designated Airport Freeway where it serves the southern entrance of DFW Airport.
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. 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.
The Dallas North Tollway is a 30.2-mile (49 km) controlled-access toll road operated by the North Texas Tollway Authority (NTTA), which runs from Interstate 35E near Downtown Dallas, Texas (USA), to U.S. Highway 380, in Frisco, Texas. On December 20, 2023, the NTTA announced the Tollway's next extension which runs 6 miles (9.7 km) through Prosper and Celina and ends at FM 428.
Interstate 635 (I-635) is a 37-mile-long (60 km) partial loop around Dallas, Texas, in the United States between I-20 in Balch Springs and SH 121 at the north entrance of the DFW Airport in Grapevine. It intersects I-35E at exits 27B and 27C but does not connect with I-35W. I-635 and a part of I-20 are collectively designated as the Lyndon B. Johnson Freeway; known locally as the LBJ Freeway, or simply LBJ. The roadway is named after Lyndon B. Johnson, the former U.S. senator from Texas and the 37th vice-president and 36th president of the U.S. Where I-635 ends at I-20, I-20 continues the LBJ Freeway designation heading west. Since the portion of I-20 between Spur 408 to I-635 retains the same names as I-635, the two highways are considered three-quarters of the beltway around Dallas. Together with Spur 408, a portion of Loop 12, and a portion of I-35E, I-635 and I-20 complete the beltway.
The Westpark Tollway, also Fort Bend Westpark Tollway, is a controlled-access toll road in Texas, serving western Houston and Harris County, and northeastern Fort Bend County.

The Harris County Toll Road Authority (HCTRA) administers the Harris County segment of the road — from just south of Beltway 8 at the county line to US 90A — and uses its purple pentagonal shield labeled as Fort Bend Toll Road. It is proposed to reach a northern terminus at the southwestern corner of Interstate 610 in the future, and SH 99 at its southern terminus.
The Trinity Parkway was a proposed six-lane toll road in Dallas, Texas (USA), to run from the State Highway 183/Interstate 35E interchange to the U.S. Highway 175/Interstate 45.

Dallas City Council had recommended that a "context-sensitive design" be used for the parkway.
The Homestead Extension of Florida's Turnpike (HEFT), designated as unsigned State Road 821 (SR 821), is the southern extension of Florida's Turnpike, a controlled-access toll road in the U.S. state of Florida maintained by Florida's Turnpike Enterprise (FTE). Spanning approximately 48 miles (77 km) along a north–south axis, it supplements the 265-mile (426 km) mainline to form the complete 309-mile (497 km) turnpike. The extension begins at its southern terminus at U.S. Route 1 (US 1) in Florida City, and transitions into the SR 91 mainline in Miramar at its northern end. Despite their designations as different state roads, the mainline and the extension are continuous in their exit numbering.
State Highway 170 (SH 170), also known as the Alliance Gateway Freeway, is a Texas state highway in the northern suburbs of Fort Worth in the Alliance area. The highway was designated in 1988.
There are approximately 25 current toll roads in the state of Texas. Toll roads are more common in Texas than in many other U.S. states, since the relatively low revenues from the state's gasoline tax limits highway planners' means to fund the construction and operation of highways.
The Sam Rayburn Tollway is a controlled-access toll road operated by the North Texas Tollway Authority that runs from Grapevine to McKinney. Its frontage roads are signed SH 121.
The North Tarrant Express (NTE) project is a total highway reconstruction of the Interstate 820 (I-820) and State Highway 121/State Highway 183 corridor between I-35W and Industrial Boulevard in Northeast Tarrant County, Texas. The NTE and the Texas Department of Transportation (TxDOT) anticipate the new highway system will relieve traffic congestion, improve safety on its roadways and have integrated plans for the anticipated traffic growth in one of the country’s fastest developing regions. When the improvements are completed, the $2.5 billion North Tarrant Express will have upgraded main highway lanes, continuous frontage roads, and 13.3 miles (21.4 km) of newly added tolled managed lanes.
