Aransas Pass was, for most of recorded history, impossible. The gap between Mustang Island and San José Island was a shallow, shifting mess of sandbars that silted up after every storm and rearranged itself with the tides. Shallow-draft ships could sometimes squeeze through. Deep-draft ships could not. The tarpon that made this coast famous and the ship channel that would eventually make it rich both depended on one thing: someone figuring out how to hold the pass open. It took thirty-nine years, three separate attempts, and an enormous amount of Hill Country granite to finally do it.
Phase One: The Brush Mattress (1880–1885)
In 1879, Congress passed a resolution authorizing the deepening of Aransas Pass. In May of 1880, Samuel M. Mansfield began the work. The design that emerged — driven by available budget and limited engineering precedent on this coast — was a five-thousand-five-hundred-foot jetty built from a brush mattress foundation topped with stone.
The logic was that the brush would settle into the sand and provide a stable base. It did not. The mattress decayed, the stone slumped, and by 1885 the project was clearly failing. In 1889, the federal government gave up and abandoned it.
Phase Two: The Bankrupt Company (1890–1897)
When the federal government left, local entrepreneurs formed the Aransas Pass Harbor Company to pick up the work. They raised private capital and began building a wooden-cased jetty system, again topped with rock. The wooden casings failed in the surf, and the company switched mid-project to an all-rock design. That was more expensive. The company ran through its money and declared bankruptcy in 1897.
After two attempts and seventeen years, Aransas Pass was still not reliably open to deep-water shipping. Federal and private dollars had both tried and both failed.
Phase Three: The Army Corps and the Granite (1899–1919)
In 1899, Congress authorized the Army Corps of Engineers to return and finish the job. This time the design was right and the execution was relentless. The north jetty came first, built out from San José Island. The south jetty followed, extending from Mustang Island.
The stone was the right stone. Enormous granite blocks — many weighing several tons — were quarried from the Llano Uplift in Central Texas and railed down to the coast. A Rockport-based contracting firm, D.M. Picton, handled much of the jetty work. Workers came from all over, including European immigrants: one named Matteo Bujan arrived from Croatia and stayed in Port Aransas, his descendants still in town.
In 1907 the north jetty was nearing completion and the south was authorized. In 1911 the work was considered substantially complete. In 1919, after another eight years of extension and reinforcement, both jetties were fully finished.

None of it would have been possible without a single-purpose railroad. The Aransas Harbor Terminal Railway was chartered on June 13, 1892, specifically to haul granite from mainland quarries to the pass. Railroad flatcars brought the stone to the shore of Redfish Bay. From there, the Terminal Railway's trestle carried the rock three and a half miles over open water, where it was transferred to barges, towed out into the Gulf, and dumped into position.
The railway operated for over fifty years. It closed in 1947. Almost nothing of it remains visible today — a few pilings, some rotted trestle wood in low tide. But the bronze bell from its steam engine sits in the Port Aransas Museum. Visitors are encouraged to touch it.
What the Jetties Built
A reliable deep-water channel at Aransas Pass changed everything. Within a decade of the jetties' completion, Port Aransas had become a serious sport fishing destination — the Tarpon Era was already underway but now had the infrastructure to support it. By the 1940s, Port Aransas was the twelfth-largest oil shipping port in the United States. Harbor Island, just inside the pass, was lined with refineries and tanker berths.
Modern tourism depends on the jetties too. The south jetty walk is the single most photographed feature on the island. Surfers ride the breaks that form against the rock. Fishermen work the channel. Dolphins chase shrimp boats into the pass. None of that happens without thirty-nine years of failed attempts followed by twenty years of granite.
