Louisiana Spur Highway 77 (Spur LA 77) is a 1.4-mile-long (2.3 km) highway that covers a glitch in the state highway system. The current LA 77 follows the routing of the original Jefferson Highway, and the LA 77 alignment follows the old road to meet LA 10 West. However, this shortcut is used to reach Morganza, to the northeast of Livonia.[2]
