The highway parallels U.S. Route 67 (US 67) except for the portion west of downtown Dallas (which was once part of I-20).

The western end and zero mile point of I-30 in Texas is at its intersection with I-20 in Parker County near Aledo.

It then travels near downtown Fort Worth on a new routing further south than the now removed Lancaster Elevated section of the freeway.

At Malvern, drivers can use US 70 or US 270 to travel into historic Hot Springs or beyond into Ouachita National Forest.

[citation needed] As I-30 enters Little Rock, I-430 leaves its parent route to create a western bypass of the city.

At this three-way junction of Interstates, I-30 turns due north for the final few miles of its route.

In October 2001, the former turnpike was named the Tom Landry Highway, after the late Dallas Cowboys coach.

[14] The proposed expressway was studied as early as 1944 but was turned down by the state engineer due to the expense.

[18] The turnpike's presence stimulated growth in Arlington and Grand Prairie and facilitated construction of Six Flags Over Texas.

At the end of 1977, the bonds were paid off, and the freeway was handed over to the state Department of Transportation, toll collection ceased, and the tollbooths were removed in the first week of 1978.

[19] The existing US 67 route was already in heavy use in the early 1950s, at which point it was twinned from just east of Dallas to Rockwall and also a rural section near Greenville and a few miles in Hopkins County.

The majority of the route was completed by 1965, but a 40-mile (64 km) stretch through rural areas built on a new alignment well away from US 67 between Mount Pleasant and New Boston remained unfinished.

[20][self-published source] Originally, the west end of I-30 was at the current intersection of I-30 and US 80 near the border of Mesquite and Dallas.

[citation needed] In April 2016, a provision designating US 67 from North Little Rock to Walnut Ridge, Arkansas, as "Future I-57" was added to the federal fiscal year 2017 Transportation, Housing and Urban Development funding bill.

Once the eastern segment of the Texarkana Loop had been upgraded to Interstate standards, I-130 was to have been signed; however, it is now part of I-49.
