Bolivar Roads & Galveston, Texas
Galveston Bay Entrance
The Texas gateway at Bolivar Roads, where long jetties lead into a web of shipping channels.
Between Galveston Island and Bolivar Peninsula, the entrance channels gather at Bolivar Roads before continuing into the bay. Red and green isophase lights mark the outer jetties, their light and dark intervals equal. Inside, channel and range lights trace the approaches to Galveston and the route toward Houston.
