Louisiana Highway 309 (LA 309) is a state highway in Louisiana that serves Terrebonne and Lafourche Parishes. It spans 8.5 miles (13.7 km) in a north-south direction along Brule Guillot Road between Chacahoula and a point west of Thibodaux.
From the south, LA 309 begins at a junction with LA 20 in an area of unincorporated Terrebonne Parish east of Gibson known as Chacahoula. Proceeding northward, LA 309 immediately crosses the BNSF/Union Pacific Railroad tracks at grade and passes underneath the elevated U.S. 90 (future corridor of I-49). (LA 20 intersects U.S. 90 just east of LA 309's southern terminus.) LA 309 crosses into Lafourche Parish and continues through uninhabited swamp for roughly half of its route. It then encounters a transition to farmland and residential subdivisions as it approaches the outskirts of Thibodaux.
About 1.5 miles from its northern terminus, LA 309 intersects LA 3107 (Talbot Avenue). In an area known as Brule west of Thibodaux, LA 309 reaches its end at an intersection with LA 1 which runs alongside Bayou Lafourche.
