2025 Map of Belle Pass

About this map

Bayou Lafourche flows south through the marshlands of Lafourche Parish to meet the Gulf of America at Belle Pass, defining a landscape where industrial infrastructure and fragile coastal waterways collide. The 2025 survey illustrates the modern development at Pass Fourchon, where a network of localized roads such as A O Rappelet Rd, A J Estay Rd, and Chevron Rd support the maritime and energy sectors. This coastline is a complex of lagoons and channels, including Bay Marchand and Timbalier Bay, separated from the open sea by narrow, shifting spits of land. Navigational features like the Evans Canal and Bayou Tartellon cut through the wetlands, providing critical passage for vessels moving between the inland bayous and the deep gulf waters.
