A Texas U-turn, or Texas Turnaround, is a lane allowing cars traveling on one side of a one-way frontage road to U-turn into the opposite frontage road (typically crossing over or under a freeway or expressway) without being stopped by traffic lights or crossing the highway traffic at-grade. This particular highway configuration originates (and is particularly common) in Texas (especially in the Dallas, Houston, Austin, and San Antonio areas), but can also be found in Jackson, Mississippi; New Orleans, Louisiana; Atlanta, Georgia; Oklahoma City, Oklahoma; and North Little Rock, Arkansas. This is also common in Michigan and Florida, where frontage roads travel along freeways. In some cases these are controlled by signals, and are similar to the Michigan left. They are also used less frequently in other areas of the world.
