Loop 12 is a state highway that runs mostly within the city limits of Dallas, Texas. The western segment of the loop is named after General Walton Walker, who served and died in South Korea. During the 1950s and 1960s, Loop 12 was the outer beltway in the Dallas area, having since been supplanted by I-635, which is itself being supplanted by the President George Bush Turnpike. Loop 12 is, however, the only state highway in Dallas that forms a complete loop (Belt Line Road is also a complete loop but is not a state road except for a stretch as part of FM 1382).
