Traversing the high, rolling plains of the Texas Panhandle, IH 27 is an intrastate route connecting the cities of Lubbock and Amarillo. Bisecting Lubbock between State Loop 289, a limited access beltway, IH 27 extends the freeway along U.S. 87 north from Lubbock County to Downtown Lubbock, where it curves eastward alongside Mac Kenzie State Park. A three level interchange joins IH 27 with Loop 289 on the north side of the city as the freeway departs for Lubbuck International Airport (LBB) and the town of New Deal.

Leading away from Hub City,  IH 27/U.S. 87 reach the city of Abernathy on the Hale County line. There the freeway briefly transitions to an urban design, dipping below the Main Street overpass east of the city center. Continuing, IH 27 shifts one mile west before bee lining northward to the city of Hale Center. Once at the city center, the freeway again navigates through an urban section, dropping below grade at Cleveland Avenue. IH 27 through both Abernathy and Hale Center are subject to closure due to flooding during heavy thunderstorms.

Beyond Hale Center, IH 27/U.S. 87 angle northeast across agricultural areas to Furguson, where a Business Loop separates eastward to the city of Plainview. The freeway mainline circumvents the west side of the city to Columbia Street, where Business Loop IH 27 returns. Northward from there, IH 27 traverses a rural route by Kress, Tulia and Happy, where U.S. 87 branches west to Canyon.

U.S. 87 combines with U.S. 60 at Canyon along an expressway leading north to IH 27. Construction of IH 27 directly overlaid the original four lane highway for U.S. 60/87 heading toward Amarillo. Within Amarillo, the freeway turns easterly ahead of the Potter County line before curving back north to conclude at IH 40, opposite U.S. 287 and the dual couplets of U.S. 60/87 through Downtown.

The Texas Department of Transportation (TxDOT) submitted an application to the American Association of State Highway and Transportation Officials (AASHTO) to extend Interstate 27 south 4.2 miles from Lubbock to County Road 7500. The extension lengthens IH 27 to the planned exchange with future Loop 88. AASHTO approved the request at the Fall 2023 Route Numbering Committee Meeting. Construction on Loop 88 – Section 3C, which includes the directional T interchange with U.S. 87, is scheduled for letting in October 2025.

High Priority Corridor

Interstate 27 is part of High Priority Corridor 38: Ports to Plains Corridor.

Parallel U.S. Routes

Interstate 27 follows U.S. 87 for its entire length, with separations between Exits 63 and 77 and again between Exits 88 and 110. U.S. 60 overlaps with IH 27 from Canyon north to Amarillo, while U.S. 84 parallels it through Lubbock.

Port to Plains Corridor

Long standing proposals advocated extending Interstate 27 south from Lubbock to IH 20 in the vicinity of Midland-Odessa, and possibly further to San Angelo, IH 10 and a border crossing with Mexico. A feasibility study for the Port to Plains High Priority Corridor was conducted in 2000, though upgrades were mostly done to U.S. 87 in place of building new stretches of freeway. The Port to Plains Corridor was previously proposed as a divided highway running 963 miles north from Laredo, Texas to Denver, Colorado. It was designated as a high priority corridor in 1998 by the U.S. Congress.1

The Ports to Plains Alliance sought a new feasibility study for extending Interstate 27 south in 2015. Having gained the support of San Angelo Mayor Dwain Morrison, the potential study required endorsement from the county before the Texas Department of Transportation (TxDOT) would move forward with it.2 Referencing the lack of a connection to the Interstate system and potential economic growth and stability, subsequent actions by San Angelo city council on March 19, 2019 endorsed the IH 27 extension. Projected costs at the time to upgrade the 500 mile long Port to Plains Corridor south from Lubbock to Laredo topped $5.2 billion. This included potential cost savings by coupling the leg between Midland-Odessa and San Angelo with the IH 14 corridor.3

The extension of Interstate 27 was signed into law as part of the $1.5 trillion fiscal year 2022 omnibus appropriations bill. The Legislation outlines a route taking IH 27 south from Lubbock to Laredo, Texas and north to Raton, New Mexico. The infrastructure bill makes the future corridor eligible for federal funding.1 The Port to Plains Corridor in Texas overlays U.S. 87 south to San Angelo, with a loop west to Midland along SH 349 from Lamesa and along SH 158 to Sterling City. The Port to Plains Corridor continues south from San Angelo along U.S. 277 to Del Rio and Carrizo Springs, and U.S. 83 to Laredo.

North from Amarillo, Texas the Port to Plains Corridor follows both U.S. 87 northwest to New Mexico via Delhart and U.S. 287 to the Oklahoma Panhandle via Stratford. The corridor lines U.S. 87 northwest to I-25 at Raton and U.S. 287 northward to Boise City, Oklahoma and I-70 at Limon, Colorado.

Texas Panhandle - 1970
Interstate 27 appeared first in the 1970 edition of the Rand McNally North American Road Atlas.

Many portions of IH 27 were designated directly over previously four lane sections of U.S. 87.

Texas Panhandle - 1984
Texas Panhandle – 1984

Outside Lubbock, the last portion of Interstate 27 open to traffic was the easterly bypass of U.S. 87 between Happy and Canyon.

IH 27/40 - Amarillo, TX - 2001
Looking southward from Downtown Amarillo at the interchange joining IH 27 and IH 40. The reconfiguration of this exchange elevated IH 40 above IH 27; the two previously met with IH 40 traveling at grade level. January 2001 webcam shot provided by John R. Detwiler.


Interstate 27 was not an original Interstate highway. It was approved by the Federal Highway Administration on December 12, 1968. Approval by the Texas State Highway Commission followed on February 1, 1969.4 The last segment of Interstate 27 (from 19th Street to 54th Street in Lubbock) opened to traffic on September 3, 1992.5,6

The turbine interchange where IH 27 and IH 40 meet south of Downtown Amarillo was reconfigured during a $33 million, three year project completed in 2001.

The exchange joining IH 27/U.S. 60-87 with IH 40/U.S. 287 in Amarillo originally lacked a direct ramp from IH 40 east to IH 27 south. Started in January 2017, construction built a new flyover replacing the previous ramp configuration using the frontage road system. The direct connector opened temporarily in September 2018, and permanently on November 15, 2018. Associated work through Spring 2019 widened the IH 27 bridge across SE 26th Avenue.7
