Farm to Market Road 640 (FM 640) is located in Wharton County. The three-mile-long highway starts at FM 102 east of Glen Flora, heads to the north and ends at FM 1161 in Spanish Camp.

A two-lane highway along its entire route, FM 640 begins at a stop sign on FM 102 1.1 miles (1.8 km) to the east of Glen Flora.^[64] According to the United States Geological Survey 1953 Glen Flora 7.5' quadrangle map, the intersection is midway between Glen Flora and the one-time community of Sorrelle.^[65] FM 640 heads straight to the north-northeast for 0.8 miles (1.3 km) then curves sharply to the northwest.^[64] Just after the curve, the highway crosses Baughman Slough, a small watercourse.^[65] After going northwest for a short distance, FM 640 bends to the right twice until it is going to the north-northeast. After about 1.0 mile (1.6 km) from the first curve, the highway curves to the north-northwest. For the next 0.9 miles (1.4 km), FM 640 goes in a straight line to the north-northwest. After curving to the left and right, FM 640 goes 0.3 miles (0.5 km) before coming to a stop sign at FM 1161 in Spanish Camp.^[64] In its final stretch the highway crosses Peach Creek and there were a number of natural gas wells in the area in 1952.^[66]

On May 23, 1951, FM 640 was redesignated to start at FM 102 near Glen Flora in Wharton County and continue in a northerly direction to FM 1161 in Spanish Camp. The distance was estimated at 3.1 miles (5.0 km).^[63]

Farm to Market Road 646 (FM 646) is a designator that has been used three times. The current use is in Galveston County, from FM 2004 at Hitchcock to FM 517 at San Leon. There is a concurrency with SH 6 in Santa Fe.

The highway begins at FM 2004 in Hitchcock, Texas. It runs north to Texas State Highway 6 in Santa Fe, Texas. It briefly merges with Highway 6, heading northwest, and then branches off and keeps heading north. The highway has intersections with Farm to Market Road 1764 and Farm to Market Road 517 before turning northeast and intersecting Interstate 45 soon after. The highway continues northeast and passes into Dickinson, where it intersects Texas State Highway 3 and turns east before intersecting Farm to Market Road 1266. The highway intersects Farm to Market Road 3436 before turning northeast again. The highway intersects Texas State Highway 146 and passes through Bacliff. Once it reaches Bayshore Drive, it turns abruptly southeast and continues into San Leon. The highway ends at its second intersection with FM 517.

FM 646 was designated on December 17, 1952 from FM 517 south to SH 6 near Alta Loma. It was formerly FM 517,^[73] and before that, FM 520.^[74] On October 31, 1958 the road was extended 6.9 miles to the Brazoria County line. On May 30, 1961 the section of FM 646 from SH 6 to the Brazoria County line was transferred to FM 1561. On October 15, 1964 the road was extended to FM 2004, replacing a section of FM 1561 (which was cancelled, as the remainder of FM 1561 became part of FM 2004) and creating a concurrency with SH 6. On May 25, 1976 the road was extended north 1.6 miles to I-45 & FM 3002. On February 8, 1980 the road was extended to FM 517 southwest of Bacliff, replacing FM 3002. On July 20, 1982 by district request, the road was extended to FM 517 in San Leon, replacing a section of FM 3436. On June 27, 1995 the section from SH 6 to UR 517 at San Leon was transferred to UR 646, but was changed back to FM 646 on November 15, 2018.

FM 646 is the possible route of Texas State Highway 99, known as the Grand Parkway between Highway 146 and Interstate 45. It will become the third loop around the city of Houston. However, many businesses would have to be destroyed for the highway to be built along the FM, so a change to the plans is likely.

FM 660 begins in rural eastern Ellis County at an intersection with SH 34 just over 1 mile east of Ennis. It travels northbound from the east–west stretch of SH 34, bridging Fourmile Creek before it banks east as it merges onto Crisp Road. As it passes through the unincorporated community of Crisp, it then banks north and snakes towards an intersection with FM 813. At this intersection, FM 813 terminates as FM 660 banks east through Bristol, before banking north and making its way down Sugar Ridge. As it travels northbound, FM 660 briefly makes it way through the Trinity River Floodplain and crests over a levee locally known as "The Bristol Bump" because of its sharp and sudden crest potentially sending unsuspecting drivers airborne for a brief moment. FM 660 then travels northeast towards Ferris through the foothills bordering the Trinity River Floodplain, intersecting with FM 710 roughly 6 miles northeast of Bristol and 2.5 miles east of Ferris. FM 660 then intersects with Interstate 45 just before reaching its northern terminus with Business Interstate 45 in downtown Ferris.

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.^[125]

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.^[126] 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.^[127] A much larger mesa, called Gail Mountain, stands on the western edge of Gail and provides a scenic backdrop for this small town.^[128]

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.^[129]

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.^[130] 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.^[131]

FM 669 was designated on September 24, 1945 from US 180 at Gail south 10 miles. On March 30, 1949, FM 669 was extended south 2.5 miles 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 27, 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.

Existed	1946–present

Farm to Market Road 677 (FM 677) is located in Montague County.^[142]

FM 677 is one of the longest farm to market roads in Montague County, and is a two-lane route for its entire length. It begins in Forestburg at a junction with FM 477.^[143] It travels northward through the rural eastern part of the county, reaching St. Jo and an intersection with US 82. It continues northward, through the unincorporated communities of Capps Corner and Illinois Bend, close to the Cooke County line.^[144] It briefly turns to the west before resuming its northward journey toward the Red River. The FM 677 designation ends as the route crosses into Love County, Oklahoma across the Taovoyas Indian Bridge; the roadway continues as Oklahoma State Highway 89.^[142]

A spur of FM 677 exists in Illinois Bend, traveling northward from mainline FM 677 approximately 0.268 mi (0.431 km). It is signed as Spur 677 using the traditional state highway spur marker.^[142]

FM 677 was designated on January 31, 1946 northward from US 82 in St. Jo approximately 5.3 mi (8.5 km). It was extended north 2.5 miles on May 23, 1951, south 2.9 miles on November 20, 1951, and again southward on December 17, 1952, to near the FM 1630 intersection.^[145] The route's designation was extended further northward to 3 miles north of Capps Corner on December 2, 1953 and to Illinois Bend on September 29, 1954; the same day also so the lengthening to Forestburg. The connection to the Red River was made on April 24, 1958, and the concurrency with US 82 in St. Jo was removed on June 30, 1961. The connection to Oklahoma was made on December 20, 1988.
