Louisiana Highway 77 (LA 77) is a state highway in Louisiana that serves Iberville and Pointe Coupee Parishes. It spans 49.11 miles (79.03 km). [1]

Route description[edit]

Louisiana Highway 77, or LA 77, travels southward from LA 10 near the old Melville Ferry roadway in Pointe Coupee Parish through Fordoche and Livonia. In Iberville Parish, it is the primary route from Plaquemine to the northern communities of Maringouin, Rosedale, and Grosse Tete. It parallels Bayou Grosse Tete for much of its course, and the landscape is mostly composed of sugarcane fields and forests along the bayou. LA 77 turns southeastward across a drawbridge over Bayou Grosse Tete and the Intracoastal Canal and parallels Bayou Plaqemine on the western bank before ending at Louisiana Highway 1 near The Island Country Club in Plaquemine.
