The ship canal approach is defined by two jetties extending into the Gulf of Mexico with distances of 4.5 miles (7.2 km) from the Bolivar Peninsula and 2.25 miles (3.62 km) 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.
