1954 Map of The Jetties

About this map

The North Jetty and South Jetty define the narrow gateway to the Texas coast in the mid-1950s, reaching miles into the Gulf of Mexico. This map details the critical maritime engineering required to maintain the Inner Bar Channel and Outer Bar Channel for navigation into the protected waters of Bolivar Roads. On the tip of Galveston Island, the site of Old Fort San Jacinto stands near the expansive East Beach and the shifting sands of Big Reef. Opposite the channel, the Bolivar Peninsula tapers into a series of tidal flats and sandbars. This survey documents the specific bathymetry and infrastructure of the era, including the Galveston Jetty Light and the established Galveston City Limits as they extended across the water.
