Interstate 27 (I-27) is an Interstate Highway, entirely in the U.S. state of Texas, running north from Lubbock to Interstate 40 in Amarillo. These two cities are the only control cities on I-27; 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 Texas State Senator Marshall Formby in 2005. The entire length of I-27 replaced U.S. Route 87 for through traffic.
