SH 7 subsequently went through several other major reroutings, truncations and extensions between 1939 and 1990, before becoming the highway it is today.

The highway travels through mostly flat, rural landscape, that lies between the Dallas-Fort Worth area and Houston.

The highway also passes several small rivers, retaining dams and man made reservoirs, as well as cutting through the Davy Crockett National Forest and passing the northern boundary of the Sabine National Forest.

About 6.5 miles (10.461 km) east of I-35, SH 7 intersects with the southern terminus of FM 2643.

The highway heads east, passing the eastern terminus of FM 935 and SH 320 near Triangle, then crosses over the Brazos River on a bridge.

[2] East of the river, SH 7 enters the town of Marlin, passing an intersection with Bus.

Further into town, SH 7 passes the southern terminus of FM 147 at Walker Street.

[2] After entering Leon County, SH 7 intersects with US 79 and Loop 208 in Marquez, then continues east crossing a set of railroad tracks.

After intersecting with FM 1147, the highway then crosses another set of railroad tracks in Concord.

Entering Centerville, SH 7 becomes Saint Mary's Street and intersects with I-45 at exit 164.

[2] Entering Crockett, SH 7/SH 21 become Goliad Avenue and intersect with the southern terminus of FM 229.

Both highways arrive at the Crockett town square, which is comprised by four one-way streets centered around the Houston County Courthouse.

East of Ratcliff, the highway briefly turns northeast again, crossing over the Neches River into Angelina County.

Where the roadway continues east as SH 103 to Lufkin, SH 7 turns briefly north, then heads diagonally northeast, passing FM 1819 near Redtown and a grade separated interchange with US 69 further northeast.

Mangham Junior Regional Airport and enters Nacogdoches becoming Fredonia Street, before reaching a freeway interchange with US 59, SH 21 and Loop 224.

The four highways run concurrently for about two blocks, where FM 1275 splits off, heading south on Rayburn Drive.

Shortly afterwards, SH 7/SH 21/Loop 224 meets with FM 2259 at a signalized intersection with Woden Road.

Continuing northeast, the highway intersects with FM 2913 and FM 711, then passes a signalized intersection, acting as the western terminus of Loop 500, entering Center as San Augustine Street.

The town square also serves as a major intersection with SH 87 and the southern terminus of FM 699.

Heading northeast from the town Square on Cora Street and Louisiana Street, SH 7 crosses under a set of railroad tracks, passing intersections with FM 2788 at Sardis Road and Loop 500, before leaving town.

On the edge of town, SH 7 passes the southern terminus of FM 1656 at Center Municipal Airport.

'[3] In 1919, the routing was mostly proposed between San Angelo and Goldthwaite, but only the segment to Paint Rock was created.

[4] Possibly due to the amount of construction necessary to build this route as proposed, on December 18, 1917, the road was rerouted via U.S. Highway 84 to Palestine, and south on U.S. Highway 287 to Crockett, following the proposed route from there.

On March 20, 1918, the road was completely rerouted via current U.S. Highway 84 through Lubbock to Sweetwater.

[14] The extension to Eddy was officially designated on August 29, 1990, replacing a portion of FM 107.

On December 20, 1917, an intercounty highway was designated from San Angelo to Fort Stockton.

SH 7-B heads east, before curving south at an intersection with Mooreville Road.

[21] This business route was previously designated as a section of FM 107, which used to continue east from I-35 in Bruceville-Eddy to SH 7 right outside of Chilton.

The business route then travels northeast on Fredonia Street for one mile (1.61 kilometers), then reaches an intersection with Bus.

US 59-F head north on South Street into downtown Nacogdoches, meeting at an intersection with Bus.
