2019 Map of Port Bolivar

About this map

Galveston Bay serves as a critical maritime corridor in this modern survey, dominated by the heavy traffic routes of the Houston Ship Channel and the Houston/Galveston Navigation Channel. The landscape is defined by its coastal vulnerability and strategic importance, featuring the Bolivar Peninsula at the southeastern edge. Here, the community of Port Bolivar sits at the nexus of the Intracoastal Waterway and the open bay, its grid of streets like Broadway Ave and Madison Ave providing access to Oyster Lake and Baffle Point. The vast watery expanse is punctuated by hazards and landmarks for mariners, including the shifting sands of Halfmoon Shoal, Hanna Island, and Hanna Reef. Along the western margin, the Texas City Dike Rd extends into the bay, illustrating the massive engineering efforts required to maintain these vital deep-water shipping lanes near the Trinity River Channel.
