Texas State Highway 40

SH 40 begins at an intersection with FM 2154 (Wellborn Road) in College Station, Brazos County, heading southeast on William D. Fitch Parkway, a four-lane undivided road. The road heads near residential subdivisions, becoming a divided highway with the median widening to include woodland. The highway heads through more wooded areas with some fields and residential neighborhoods, turning to the east. SH 40 turns to the northeast and the median narrows, with the road becoming undivided again as it comes to its eastern terminus at an interchange with SH 6.^[1][3][4]

 

A previous highway, also called SH 40, existed from March 17, 1919^[5] until September 26, 1939, and ran from the Oklahoma state line north of Gainesville down through Denton, Dallas and Beaumont before ending in Sabine Pass. On March 18, 1919, a spur route, SH 40A that went from Denton and ended in Fort Worth was designated, so SH 40A and the route of SH 40 north of Dallas replaced SH 16.^[6][7] On August 21, 1923, this spur had become an extension of SH 10. That same day, SH 40 was truncated to Voth (north of Beaumont), with the section from Voth to Beaumont already part of SH 8 and the section from Beaumont to Sabine Pass cancelled.^[8] SH 40 was rerouted over a portion of SH 37 between Rusk and southeast of Lufkin, while the old route was either cancelled or transferred to SH 37. On May 22, 1933, SH 40 Spur was created to Baxter.^[9] On January 24, 1938, SH 40 Loop was designated to Keltys.^[10] On April 19, 1938, SH 40 Bypass was designated from SH 40 to SH 114.^[11] On June 21, 1938, SH 40 Spur was designated to Forest.^[12]

The Gainesville to Dallas portion became US 77 in 1929. In 1932, the Dallas to Jacksonville stretch had become part of US 175. The last remaining portion of old SH 40, Jacksonville to Port Arthur, became part of US 69 in 1934. On September 26, 1939, SH 40 was cancelled in favor of these US Highways. The SH 40 Loop and SH 40 Spur routes were renumbered as Loop 12 (Dallas), Spur 29 (Forest), Loop 36 (Keltys), and Spur 65 (Baxter).

SH 40A was a spur route proposed on September 16, 1926, going from St. Augustine south to Zavalla.^[13] This route was actually designated as SH 8B instead(now SH 147).

Interstates 35E and 35W roughly follow the old SH 40 routes from Dallas and Fort Worth, respectively, to Denton, and the old route from Denton north is approximated by Interstate 35.

The entire route is in College Station, Brazos County.
