[2] FM 2 begins at CR 327 in Courtney, approximately 1.5 miles (2.4 km) east of the Washington County line at the Brazos River.

[2] In 2017, TxDOT announced plans to convert the at-grade intersection between FM 2 and SH 6, regarded as extremely dangerous,[4] into a diamond interchange.

FM 9 straddles the east side of the Longhorn Army Ammunition Plant before ending near the south shore of Caddo Lake.

[29] A previous FM 9 was formed from Midland south 12.0 miles (19.3 km) on March 26, 1942, when the route was designated from part of SH 137.

From there, it continues north through the community of Fitzhugh to its terminus at RM 3238 (Hamilton Pool Road), approximately six miles west of Bee Cave.

[32] A planned expansion of RM 12 between Dripping Springs and Wimberley to a four- and five-lane divided highway was defeated as part of a county bond election in 2007.

The original portion of RM 12 through San Marcos was redesignated as an extension of SH 80 on the state highway system on June 24, 2010.

It begins at Loop 323 in Tyler and travels northward with a major intersection at I-20 near Shady Grove before terminating at SH 154 south of Winnsboro.

The road proceeds along State Park Highway through Shady Grove (where it intersects I-20) and Red Springs, where it turns to the northeast.

The road was extended to the current western terminus just west of Colfax and eastward to Lindale on June 11, 1945, creating a concurrency with SH 110.

[54] On April 29, 1942, another section was added from Robert Lee, Texas north 6.0 miles (9.7 km) to the county road to Sanco.

FM 21 was designated on April 29, 1942, as a 5.5-mile (8.9 km) road traveling from SH 11 to around Lake Bob Sandlin State Park.

On May 7, 1970, a section west of US 69 at Craft, connecting to FM 347 south of Jacksonville, was added, increasing the length by 1.2 miles (1.9 km).

On February 15, 1950, the highway was extended from Wortham to the Limestone County line, replacing FM 1450 and adding approximately 1.6 miles (2.6 km).

FM 28 runs concurrently with these highways for about one mile (1.6 km) before again heading north, reaching its northern terminus at County Roads 200 and 303.

[77] The FM 29 designation was later applied to a road in Val Verde County, beginning at US 90 (later Loop 406, now Spur 406) northwest of Devils River and heading northeast to Lake Walk.

[93][94][95] The route crosses I-27/US 87 east of Cotton Center, running in a southern direction concurrent with the freeway's frontage road between exits 32 and 31.

The road begins at US 82 west of Petty and turns north and east to Maxey, then southeast through Brookston and Roxton to Ben Franklin.

The road's southern portion was expanded on February 28, 1945, to include US 190 at North Zulch, and the northern strip received a segment from Personville to Jewett.

The road begins from FM 303 southeast of Sundown and turns about 48 miles (77 km) eastward bypassing Ropesville and Slide before eventually returning to Bus.

On June 11, 1945, FM 43 was redesignated Ranch to Market Road 43 (RM 43) and a section from Eldorado to the Menard County line was designated, creating a gap.

On May 26, 1949, FM 48 was extended north and west 2.3 miles (3.7 km) to a road intersection, and the old route was changed to a spur connection.

Skirting the northwestern fringes of the Dallas-Fort Worth Metroplex, it is available as a more scenic and less-congested shortcut between I-20 west of Weatherford and I-35 north of Gainesville.

On July 25, 1950, it was extended from the Coleman County line to 1.8 miles (2.9 km) northwest of Glen Cove, closing the gap.

On August 1, 1944, FM 60 was extended from a point near the eastern bank of the Brazos River to the State Experimental Sub Station, closing the gap.

[143] The road proceeds to the east away from town and is joined from the north by FM 904 before the combined route enters Pecan Gap and Delta County.

The road then intersects SH 24 which bypasses central Cooper on the northwest, and ends at the state highway's business route through town.

A previous route numbered FM 74 was designated in Ellis and Hill counties on March 8, 1943, connecting Waxahachie and Maypearl.

The road begins at SH 20 in the Ascarate district of El Paso and heads southeastward to Clint, passing Loop 375 in the process.

A previous route numbered Ranch to Market Road 93 (RM 93) was designated on February 11, 1944, from US 290 at or near Austin to US 281 south of Marble Falls.
