Bolivar Roads is a natural navigable strait fringed by Bolivar Peninsula and Galveston Island emerging as a landform on the Texas Gulf Coast.[2] The natural waterway inlet has a depth of 45feet with an island to peninsula shoreline width of 1.5miles.
The ship canal approach is defined by two jetties extending into the Gulf of Mexico with distances of 4.5miles from the Bolivar Peninsula and 2.25miles from Galveston Island. The jetty harbor entrance originated in the 1890s as a preventative structure to inhibit the coastal sediment transport progressions by means of deviations with the continental margin and the Gulf Stream ocean current.
The Bolivar Roads channel tailors a nautical navigation gateway for Galveston Bay, Houston Ship Channel, Port of Galveston, and West Bay.
