FM 600 begins at I-20 in Abilene and runs in a northern direction along West Lake Road before turning northeast at FM 3308 and turning back north at FM 3034. In northern Abilene, the highway runs near the western shore of Fort Phantom Hill Lake, leaving the city limits north of the FM 1082 intersection. FM 600 runs through rural areas of Jones County, intersecting US 180 east of Anson and has a short overlap with SH 6 through the town of Avoca. After the overlap with SH 6, the highway runs in an eastern direction before turning back north at County Road 223. FM 600 crosses over Lake Stamford before sharing an overlap with FM 618 near Paint Creek. The highway runs through rural areas of Haskell County before ending at an intersection with US 380 on the eastern edge of Haskell.

## FM 669

Farm to Market Road 669 (FM 669) is located in West Texas. It extends in a northerly direction for 68.8 miles (110.7 km) from Big Spring in Howard County to Post in Garza County.
Beginning at a complex junction with Farm to Market Road 700 and Texas State Highway 350 on the north side of Big Spring, Farm to Market Road 669 initially runs for 15 miles (24 km) in a northerly direction across the level plains of the Llano Estacado, passing numerous cotton fields and rural farm homes. Near the intersection of FM 1785, FM 669 drops off the Caprock and enters the rolling ranch and oil country of Borden County. The undulating, broken land of Borden County was carved by numerous ephemeral tributaries of the upper Colorado River that typically originate as springs along the Caprock Escarpment to the west and generally flow across the county in an easterly direction.
After crossing the Colorado River, about 5 miles (8.0 km) north of the Howard–Borden county line, FM 669 continues north toward Gail, the county seat of Borden County. Near Gail, one passes two prominent erosional remnants of the Llano Estacado. To the south of Gail, one can see a conspicuous landmark known as Mushaway Peak (also known as Muchakooaga, Muchaque Peak or Cordova Peak); this small butte stands on high ground between Grape Creek and Bull Creek, two tributaries of the upper Colorado River. A much larger mesa, called Gail Mountain, stands on the western edge of Gail and provides a scenic backdrop for this small town.
In Gail, FM 669 crosses U.S. Highway 180, which runs west–east from Lamesa to Snyder and beyond. Continuing north, FM 669 draws closer to the edge of the Llano Estacado, which can be seen 5 miles (8.0 km) to the west. Approximately 6 miles (9.7 km) north of Gail is a junction with FM 2350, which leads to Fluvanna and the Brazos Wind Ranch, to the east.
Farther north, near the Borden–Garza county line, FM 669 reaches a high point that divides the drainage of the upper Brazos and Colorado rivers. Along this drainage divide, the land is highly denuded with many small buttes and hoodoos. Less than a mile north of the county line is a historical marker that describes an archaeological site where the "Garza Point" was first identified. These distinctive arrowheads were constructed from local flint, chert, and obsidian by Native Americans living and hunting in this area around A.D. 1440 to 1500.
Around 5 miles (8.0 km) north of the Borden–Garza county line, FM 669 crosses the Double Mountain Fork, a major tributary of the upper Brazos River. From the colorful sandy bed of the Double Mountain Fork, FM 669 climbs 450 feet (140 m) over a distance of 6 miles (9.7 km) as it ascends the Caprock to the high plains of the Llano Estacado. FM 669 remains on the level plains for a short distance of only 3 miles (4.8 km) before suddenly dropping off the Caprock and descending 200 feet (61 m) back to the rolling plains and to the town of Post, the county seat of Garza County. Within the city limits of Post, FM 669 terminates at a junction with U.S. Route 380.
FM 669 was designated on September 24, 1945, from US 180 at Gail south 10.0 miles (16.1 km). On March 30, 1949, FM 669 was extended south 2.5 miles (4.0 km) to a county road. On November 20, 1951, FM 669 was extended to FM 1584 at Vealmoor. On May 5, 1952, FM 669 was extended to US 87, replacing FM 1857. On October 30, 1953, the section of FM 669 from the current junction with FM 1785 to US 87 was renumbered FM 1785. FM 669 instead extended south to SH 350 near Big Spring, replacing FM 817. On November 21, 1956, FM 669 was extended north to FM 1313. On May 1, 1965, the section of FM 1313 from FM 669 to US 380 was transferred to FM 669.
