Russell Fork Iron Truss Bridge
Bertram, Burnet County, Texas
Marker Inscription
Two miles south of the Joppa Community Church and Center, and six miles northeast of Bertram, stands an Iron Truss Pratt bridge over the Russell Fork of the North San Gabriel River. On September 5, 1910, the Burnet County Commissioners Court called an election to fund the construction of two bridges within Burnet County. The vote passed and bids opened for the Oakalla Bridge and Russell Fork Bridge. Land for the Russell Fork Bridge was purchased from the Asher family, an active and well-known family in the Joppa area. The design and materials for the bridge were provided by the Missouri Valley Bridge & Iron Company of Leavenworth, Kansas. The total length of the 1911 Truss Bridge is 102 feet, with diagonals constructed according to the Pratt Truss design, first developed in 1844 under Thomas and Caleb Pratt. The Russell Fork Iron Truss Bridge played an important role in the everyday lives of the Ashers and many other families in the Joppa community. Traveling to neighboring towns to conduct business was simplified. In addition, life on the river and under the bridge was a large form of entertainment and relaxation during the great depression and World War II. The Iron Truss Bridges of Burnet County built in the early 20th century expanded the economic progress of the rural communities, introduced higher education to many young people and broadened opportunities, and also provided a place for entertainment and recreation for the surrounding area.

The Story
In 1910 Burnet County voters approved funding for new bridges, and the following year this 102-foot Pratt-truss iron span rose over the Russell Fork of the North San Gabriel River, built by the Missouri Valley Bridge & Iron Company. Its diagonal-web design descended from the truss patented by Thomas and Caleb Pratt in 1844. For the Asher family and their Joppa-area neighbors, the bridge eased trips to market—and its shaded riverbank became a gathering place through the Depression and World War II.
Why it matters
It represents the early-twentieth-century farm-to-market bridge-building that pulled isolated rural communities into the wider economy and modern life.
The story behind this marker
AI contextThe era
In the opening decades of the twentieth century, rural Texas was still a place where a creek could cut a community off from the world. Roads were dirt, wagons were the family car, and a swollen river at a bad ford could mean no trip to town, no market for your crops, and no school for your children. The great project of that era was connecting these isolated places — and the humble hero of that project was the bridge.
Burnet County, in the Hill Country northwest of Austin, felt this keenly. Its scattered farming communities, like the Joppa area, needed reliable crossings over waterways such as the Russell Fork of the North San Gabriel River. So in September 1910 the Burnet County Commissioners Court called an election to fund the construction of two bridges. The vote passed, bids opened, and the work began.
This was democracy at its most local and practical: neighbors voting to tax themselves so that everyone could get across the river. The bridges that resulted were products of a national bridge-building boom, when standardized iron and steel spans, shipped and assembled from distant works, were transforming the American countryside.
People & events
The land for the Russell Fork Bridge was purchased from the Asher family, well known and active in the Joppa community — a reminder that these public works were stitched into the lives of specific families, not dropped from above. The design and materials came from the Missouri Valley Bridge & Iron Company of Leavenworth, Kansas, one of the many specialized firms that fabricated iron truss bridges and shipped them across the country to be raised on-site.
Completed in 1911, the span runs 102 feet, its diagonals built to the Pratt truss design. That design carries its own bit of history: it was first developed in 1844 under Thomas and Caleb Pratt, and it became one of the most widely used truss forms in America precisely because it was efficient and well suited to iron and steel construction. The bridge you see is a working descendant of that mid-nineteenth-century idea.
But the marker insists on something more than engineering. For the Ashers and their neighbors, the bridge made trips to neighboring towns simpler — and its riverbank became a place of life. Through the hard years of the Great Depression and World War II, the shade under the bridge and the water beside it were a favorite spot for entertainment and relaxation, a small free pleasure in lean times.
Its place in the American story
This modest iron span belongs to one of the quiet, transformative chapters of American history: the farm-to-market bridge-building of the early twentieth century that pulled rural communities out of isolation. Bridges like this one, multiplied by the thousands across the country, did more to change daily life in the countryside than almost any other public work — turning a day's difficult journey into a simple errand.
The marker names three kinds of change the Iron Truss bridges of Burnet County brought: they expanded the economic progress of rural communities, they broadened access to higher education for young people, and they gave people a place for recreation. That trio — commerce, schooling, and simple joy — is a remarkably complete picture of how infrastructure reshapes a place. A bridge is never only about crossing water.
There's also an engineering lineage worth honoring. The Pratt truss, dating to 1844, was one of the standardized designs that let a Kansas company fabricate a bridge and a Texas county erect it — the kind of interchangeable, catalog-ordered engineering that industrialized America and made even a small rural crossing a product of a national economy.
If you visit
This is a find for people who love the back roads. The bridge stands a couple of miles south of the Joppa Community Church and Center and about six miles northeast of Bertram, out where the Hill Country keeps its quiet. Getting there is part of the reward — the kind of drive where the pavement narrows and the country opens up.
When you arrive, look at the ironwork. A Pratt truss has a clear, readable logic to it: the diagonal members are arranged to handle the pulling forces as loads cross, and once you see the pattern you can't unsee it. At 102 feet, this is a bridge built to human scale, and its riveted iron carries the honest, hand-assembled character of its era.
Then look down at the river. Remember that for the families here, this shaded bank wasn't just a crossing but a gathering place through the Depression and the war years. It's easy to picture. Pair this span with the other historic Iron Truss bridges of Burnet County for a genuinely offbeat road trip through the region's rural past — bring a good map, take it slow, and enjoy the water.

Joppa Iron Truss Bridge
Bertram, TX
The small community of Joppa grew up around a church and school in the 1880s, and as Burnet County's railroad-driven population climbed, voters approved a 1906 bond to build three truss bridges nearby. Completed in 1907, this 136-foot Pratt-truss span—the last survivor of that group—carried families to neighboring towns and, crucially, let rural young people reach schools beyond the elementary grades. Its riverbank was also a favorite spot for rest and recreation through hard times.
Bertram School
Bertram, TX
When the railroad reached this spot in 1882, the new town of Bertram raised one of its first buildings as a combined school, Sunday school, and Masonic hall—seeded by a $50 gift from the railroad executive it was named for. By 1909 a booming cotton economy had swelled enrollment past 260 students, prompting a handsome two-story brick schoolhouse. In its early years children often skipped the first weeks of class to pick cotton in the fields.
Bertram
Bertram, TX
Bertram was born in 1882 when the Austin and Northwestern Railroad ran its line through the area, drawing residents — and even whole buildings — from the older settlement of South Gabriel two miles away. Named for Austin merchant Rudolph Bertram, who helped finance the railroad, the town became an agricultural marketing hub, booming during World War I before Depression and changing transportation slowed its growth. It remains a farming community whose founders' descendants still live nearby.
Site of Town of Strickling
Bertram, TX
Strickling grew up in the 1850s as a rural crossroads on the Central Texas frontier, named for Martha Webster Strickling, who settled here in 1853. As a child she had survived the infamous Webster Massacre near Leander and months of Indian captivity—a harrowing frontier ordeal. With a post office established in 1857, the town became a mail terminal and stage stop where lumber and buffalo hides moved through, supporting a school, churches, a doctor, and stores until the railroad bypassed it in 1882.
