Texas State Highway Loop 79

Loop 79 begins at an intersection with US 277 southeast of Del Rio.[3] The roadway travels to the north past the western edge of Laughlin Air Force Base; an interchange with Spur 317, whose designation was extended to connect to the then-proposed Loop 79 in 2008, provides access to the military facility.[4] Loop 79 then briefly enters Del Rio city limits, where it has an interchange with US 90, before curving to the northwest and intersecting RM 2523, known locally as Hamilton Lane.[5] The route then travels through sparsely populated Val Verde County before turning to the west, crossing US 277 / US 377 at an interchange before reaching its northern terminus at an intersection with US 90.[1]

A route numbered Loop 79 was originally designated on September 25, 1939, and served as a loop in Stinnett. That designation was cancelled on June 21, 1990, when that roadway became a business route of SH 152.[1]

The present Loop 79 was designated by TxDOT on June 26, 2008.[1] Construction on the route began in March 2010 and the roadway opened to traffic in April 2012.[2] Loop 79 is classified as a super-2 highway, with interchanges at US 277 / US 377 in the north, US 90 in the east, and at the access road to Laughlin Air Force Base.

The entire highway is in Val Verde County.
