Interstate 27 (I-27[a]) is an Interstate Highway, entirely in the US state of Texas, running north from Lubbock to I-40 in Amarillo. These two cities are the only control cities on I-27;[3] other cities and towns served by I-27 include (from south to north) New Deal, Abernathy, Hale Center, Plainview, Kress, Tulia, Happy, and Canyon. In Amarillo, I-27 is commonly known as the Canyon Expressway (or Canyon E-Way), although it is also called Canyon Drive on its access roads. I-27 was officially designated the Marshall Formby Memorial Highway after former attorney and State Senator Marshall Formby in 2005.[1] The entire length of I-27 replaced US Highway 87 (US 87) for through traffic. An extension of I-27 north to Raton, New Mexico, and south to Laredo, Texas, was approved in 2022.
