Louisiana Highway 308 (LA 308) is a state highway in Louisiana that serves Ascension, Assumption, and Lafourche Parishes. It spans 82.5 miles (132.8 km), following the east bank of Bayou Lafourche from Donaldsonville to Golden Meadow.[1] It parallels LA 1 during its entire route, as LA 1 follows the west bank of the bayou.
Route description
LA 308 is the eastbank counterpart to LA 1, as it follows the east side of Bayou Lafourche. As the eastbank of Bayou Lafourche is generally less populated than the westbank, LA 308 serves as a slightly quicker route towards south central Louisiana and lower Bayou Lafourche than LA 1. Throughout its route, there are bridges that cross Bayou Lafourche to connect LA 308 to LA 1 and local communities. LA 308 is known as Bayou Road in Thibodaux and East Main Street south of Larose.
The route begins in Donaldsonville at LA 3089 and is known as East Bayou Road in that community. It passes through the following communities: Belle Rose, Plattenville, Thibodaux, Raceland, Mathews, Lockport, Larose, Cut Off, and Galliano. Just north of Golden Meadow, LA 308 crosses Bayou Lafourche over a steel movable lift bridge built in 1970 and intersects at LA 1, the southern terminus. LA 1 continues towards Leeville and Grand Isle.
