Roma-San Pedro International Bridge
Roma, Starr County, Texas
Marker Inscription
Erected by the Starr County Bridge Company, this single span steel suspension bridge was built over the Rio Grande in 1928. This is the only surviving suspension bridge constructed on the international border of the United States and Mexico. The 700-foot long steel bridge was designed by engineer George Cole of Houston, and built by Joseph Erastus Pate. It represents an early business enterprise between the United States and Mexico. This crossing point has been in continuous use from prehistoric times to the present. Recorded Texas Historic Landmark - 1996

The Story
Built over the Rio Grande in 1928 by the Starr County Bridge Company, this single-span steel suspension bridge linked Roma, Texas, with San Pedro, Mexico. Designed by Houston engineer George Cole and built by Joseph Erastus Pate, its 700-foot span is the only surviving suspension bridge on the U.S.–Mexico border. The crossing it served has been in use, the marker notes, since long before the bridge existed.
Why it matters
As a rare surviving international suspension bridge, it stands for the deep commercial and human ties across the Rio Grande and the enterprise that bound two nations at the border.
The story behind this marker
AI contextThe era
By the 1920s, the Rio Grande border was a place of steady exchange. Towns faced each other across the river, families and businesses had ties on both banks, and the crossings between them mattered to daily life and commerce alike. Yet moving people and goods across the river still often meant ferries and fords rather than fixed spans.
This was also an age of ambitious engineering and local enterprise. Around the country, private companies were building bridges as business ventures, betting that a reliable crossing would pay for itself in tolls and trade. Steel and new engineering methods made spans possible that earlier generations could only dream of.
Along the border, that spirit met the particular opportunity of the river itself. A well-placed bridge could turn a historic crossing point into a modern gateway — and bind the economies of two nations a little more tightly together.
People & events
In 1928, the Starr County Bridge Company erected exactly such a span across the Rio Grande, linking Roma, Texas, with the town on the Mexican side of the river. It was a single-span steel suspension bridge, about 700 feet long — a serious piece of engineering for a border crossing of its day.
Two men stand behind it. The engineer was George Cole of Houston, who designed the bridge; the builder was Joseph Erastus Pate, who brought the design into steel and stone. Together their names mark the meeting of design and construction that raised the span.
The bridge represented an early cross-border business enterprise, a private venture connecting the United States and Mexico at a spot that people had used to cross for an extraordinarily long time. As the marker notes, this crossing point has been in continuous use from prehistoric times to the present — the 1928 bridge was simply the modern chapter of a very old story. It was designated a Recorded Texas Historic Landmark in 1996.
Its place in the American story
The bridge earns its place in the larger American story as a rare survivor: of the suspension bridges built along the United States–Mexico border, it is the only one still standing. That alone makes it a monument to a vanished style of border engineering.
But its deeper significance is what it represents. A privately built international span speaks to the enterprise and ambition that knit the two countries together at the border, and to an era when local companies took on projects of national reach.
And it embodies the long human continuity of the crossing it served. That people have moved across the river at this point since ancient times, and still do, makes the bridge a single visible link in a chain of connection stretching back beyond record — a reminder that borders are also meeting places.
If you visit
Come to look at the bridge as a work of design. Trace the sweep of the single steel span and the lines of a suspension crossing built in the 1920s, and remember you're looking at the last of its kind on this border — a survivor worth lingering over.
Give equal attention to the setting on the American side. Roma's old riverfront and its historic buildings carry real distinction, and the bridge reads best as part of that older townscape, where the river below has drawn people to cross for uncountable generations.
Standing at the river's edge, look across to the Mexican town on the far bank and let the idea of continuity settle in — that this exact spot has been a crossing since long before the steel went up. For a road trip through the lower Rio Grande country, it's a stop that rewards a slow, thoughtful pause more than a quick photo.

Spiderweb Railroad
Mission, TX
When dirt roads still bogged down the Lower Rio Grande Valley, civil engineer and land promoter Sam A. Robertson began building the San Benito & Rio Grande Valley Railroad in 1912. As spurs branched out to reach far-flung farm communities, the sprawling network earned the nickname the "Spiderweb Railroad." With just over 100 miles of track, it became part of the Missouri-Pacific system in 1924.
John H. Shary Home
Palmhurst, TX
Built in 1917, this home belonged to John H. Shary, the developer whose irrigation schemes and marketing turned the Lower Rio Grande Valley into a citrus empire in the early 20th century. Shary championed the region's canals and schools, and his family kept the house at the center of Valley life for decades. In 1953 his daughter and son-in-law, Governor Allan Shivers, hosted President Dwight D. Eisenhower here during the dedication of nearby Falcon Dam.
Sam and Marjorie Miller House
McAllen, TX
Samuel Lynn and Marjorie Williams Miller were among the builders of early McAllen, with Sam's hand in nurseries, banking, real estate, and the Hidalgo International Bridge, and Marjorie active in civic life through the Order of the Eastern Star. In 1930 Sam donated 109 acres for a municipal airport that grew into McAllen Miller International. Their English Tudor Revival home, designed in 1937 from Marjorie's own plans after a trip to England, showcases local craftsmanship in stone, half-timbered gables, and gumwood detailing.
Vela Building
Hidalgo, TX
In 1904 Crisoforo Vela and his wife Florinda moved to Hidalgo, and within a few years he took over the ferry and rowboat service linking the town with Reynosa, Mexico. That river crossing was a key commercial artery in the early growth of the Rio Grande Valley, and the Vela family ran it until the first Reynosa–Hidalgo bridge opened in 1926. Vela lived in this house until his death in 1932, and it has remained in his family for generations.
