U.S. Highway 75 (US 75) is a part of theU.S. Highway System that travels fromI-345 inDallas, Texas northward to theCanadian border inNoyes, Minnesota. In the state ofTexas it runs from I-345 in Dallas and heads north to theOklahoma state line, a distance of about 75.3 miles (121.2 km).

In the initial assignment of state highways in 1917,Dallas-Fort Worth and Houston were connected by a branch ofState Highway 2 (SH 2, theMeridian Highway), which ran viaWaco andBryan and continued on toGalveston. The more direct route followed by US 75 was not initially part of the system betweenRichland (connected to Dallas bySH 14) andHuntsville (connected to Houston bySH 19).^[2][3] This Richland–Huntsville cutoff was added by 1919 asSH 32,^[4] and US 75 was assigned to the alignment, as well asSH 6 north of Dallas, in 1926.^[5] The branch of SH 2, which US 75 followed between Houston and Galveston, eventually became part of SH 6,^{[citation needed]} and these numbers were dropped in the 1939 renumbering.

Prior to the coming of theInterstate Highway System in the late 1950s, the only improvements to US 75 in Texas beyond building a two-lane paved roadway were in the Houston and Dallas areas.^{[citation needed]} However, the highways in and near these cities included some of the firstfreeways in the state: the Gulf Freeway (Houston, opened to traffic on October 1, 1948) and theCentral Expressway. WhenI-45 was built in the 1960s, its alignment bypassed many of the towns and built-up areas betweenDowntown Dallas andHouston. The bypassed routes retained the US 75 designation until the designation was truncated to Downtown Dallas in 1987. Many of the original alignments continue to exist under other designations.

In Dallas, the route followed what is now theGood Latimer Expressway (formerlySpur 559)^[6] southeast, out of downtown, alongUS 175 and south alongSH 310.^[7]

NearFerris,Trumbull,Palmer,Ennis, andCorsicana I-45 veers east to avoid the more populated areas. The old US 75 alignments through these towns, decommissioned in 1987, now carry the following designations:

• I-45 Business-J (originallyLoop 560) throughFerris^[8]
• Loop 561 throughTrumbull^[9]
• I-45 Business-H throughPalmer (originallyLoop 562)^[10]
• Spur 469,I-45 Business-G (originallyUS 287 andSpur 563) throughEnnis^[11]
• Interstate 45 Business-F (originallyLoop 564) throughCorsicana^[12]

ThroughStreetman,Fairfield,Buffalo,Centerville,Madisonville,Huntsville,New Waverly,Willis, andConroe, US 75 followed what is nowSH 75.^[13]

In Galveston, the alignment ofSH 87 from 20th Street to the southern terminus of I-45 was also part of US 75 until its 1987 truncation.^[14]

In other cases alignments were bypassed while US 75 remained in existence; they now carry the following designations:

• SH 3 throughLa Marque,Dickinson,League City,South Houston andHouston, bypassed 1952^[15]
• SH 5 from north ofDallas viaPlano,McKinney,Anna andVan Alstyne toHowe, bypassed 1959-1967^[16]
• SH 91 fromSherman toDenison, bypassed 1984^[17]

US 75 begins atI-345, an unsigned auxiliary route ofI-45 and heads north, first interchangingSpur 366 in the northeastern part of downtownDallas. The highway then interchanges withSL 12 (Northwest Highway) before forming theHigh Five Interchange withI-635. Then, it interchanges with thePresident George Bush Turnpike as it continues north throughPlano. It then interchanges with theSam Rayburn Tollway, becoming concurrent withSH 121 and then heads throughMcKinney and interchanging withUS 380. The stretch through McKinney is largely unchanged from its original design except for its intersection at theSam Rayburn Tollway.^[18] to replace the original interchange. Plans to upgrade the facility through and north of McKinney are under way with the reconstruction of the US 380 bridge. US 75 then splits from SH 121 inMelissa and continues north. InSherman, the route crosses overSH 56 and thenUS 82. North ofDenison, it becomes concurrent withUS 69 for the next 2 miles (3.2 km) before crossing over theRed River and intoOklahoma.

Theexit numbers for US 75 are not based on mile markers; instead, the exits were numbered consecutively (the only remaining stretch of road in Texas with such a system). As the bypass route was completed around the Sherman–Denison area, the numbering system was continued for the new exits. Upon completion of the widened Central Expressway through Dallas, the exit numbering was changed for the section south of I-635 to correspond with the new (and fewer number of) exits, based on mileage, but the numbering system north of I-635 was left unchanged, thus explaining the gap in the current numbering system.
