Texas State Highway 86
State Highway 86 is a state highway in the U.S. state of Texas that runs from Texico to Estelline. This route was designated on August 21, 1923 as the renumbered State [Highway 5 |SH 5A]. On September 17, 1923, the section from Estelline to Turkey was cancelled, as Texas State [Highway 18|SH 18] extended northeast from Turkey to Memphis. By 1929, it was shortened to Bovina, as it was constructed on that route, instead. It has travelled its present course since then, except for the addition of the northern portion of SH 18 between Turkey and Estelline on December 22, 1936.
