 The Barataria Road was graveled in 1927, and it was almost entirely paved in 1939.The alignment remained virtually the same during the pre-1955 era, although road maps of the 1920s and 1930s showed two differences that most likely never existed and were later corrected.Until the early 1930s, the Barataria Road branch of Route 30 was often shown to connect with the main branch of the highway at Westwego rather than Marrero.
