Railroad Bridges Over the Pecos
Del Rio, Val Verde County, Texas
Marker Inscription
Railroad Bridges Over the Pecos A major tributary of the Rio Grande, the Pecos River was long a barrier to transportation, particularly across the deep gorge that once marked its joining with the Rio Grande. Construction of the first railroad bridge over the Pecos took place in 1882 as part of the transcontinental route of the Southern Pacific Railroad across the lower portion of the United States. Access to the bridge, which was then deep in the canyon, was by means of a circuitous route and two tunnels. In 1890, Southern Pacific officials began planning for a new bridge, one that would cut directly across the ravine by means of a high-line viaduct that would save miles and straighten the route. Work began in late 1891 and was completed within three months at a cost of more than $250,000. Supported by 24 towers, the bridge was the highest in North America and the third highest in the world at the time of its completion. Passenger trains slowed to six miles per hour before crossing it and stopped while on the bridge to afford travelers a view. During World War II, the Pecos High Bridge became essential to the transportation of war materials. In response to heavier trains and the war demand, a new bridge was built in 1944, with special permission from the War Production Board to use "critical materials" in its construction. The 1944 Pecos High Bridge remains in use, although the gorge is not so deep as it once was, due to the rising of the river with the construction of Amistad Reservoir. (2002)

The Story
The deep gorge where the Pecos meets the Rio Grande long defied transportation until the Southern Pacific bridged it in 1882 on its southern transcontinental line, reached by a circuitous route and two tunnels. In 1891–92 crews replaced it with a high-line viaduct on 24 towers — briefly the highest bridge in North America — where trains slowed to a crawl and even halted so passengers could take in the view. Wartime demand brought the current 1944 high bridge, built with critical materials released by special War Production Board permission.
Why it matters
These bridges opened a southern transcontinental route across one of the West's most formidable natural barriers and later carried the materials that fed the American war effort.
The story behind this marker
AI contextThe era
In far West Texas, near where the Pecos River joins the Rio Grande, the land is cut by deep canyons through dry limestone country. For travelers and builders alike, the Pecos gorge was a serious obstacle. Crossing it meant either climbing down into the canyon and back out or going a long way around.
In the early 1880s, railroad companies were racing to finish transcontinental lines across the country. The Southern Pacific was pushing a southern route that would tie California to Texas and the Gulf Coast, crossing some of the emptiest and roughest terrain in the United States. Somewhere in this stretch, the line had to get across the Pecos.
The railroad's first answer in 1882 was a low bridge at the bottom of the canyon. Trains reached it on a winding route that ran through two tunnels. It worked, but it was slow and indirect. As traffic grew through the late 1800s, the railroad started looking for a better solution.
People & events
In 1890, Southern Pacific officials began planning a dramatic shortcut: a high viaduct that would cross the ravine in one straight line, cutting miles off the route. Work started in late 1891, and crews finished it in about three months, an astonishing pace for such a structure. It cost more than $250,000, a huge sum at the time.
The new bridge stood on 24 towers high above the river. When it was finished, it was the highest bridge in North America and the third highest in the world. The railroad knew it had built a spectacle and treated it like one. Passenger trains slowed to six miles an hour before crossing, then stopped on the bridge so travelers could look down into the canyon.
World War II brought a new kind of pressure. The Pecos High Bridge became a key link for moving war materials, and trains were getting heavier. Building materials were tightly controlled during the war, so the new bridge needed special permission from the War Production Board to use "critical materials." The replacement opened in 1944.
That 1944 bridge is still in use. The canyon below it has changed, though. After Amistad Reservoir was built downstream, the water rose and the gorge became less deep than it was when the first bridges went up.
Its place in the American story
The Pecos bridges were part of what made a southern transcontinental railroad possible. Once that route was complete, goods and people could travel between the Pacific Coast, Texas, and the Gulf on a line that ran across the southern edge of the country. That connection helped draw the Southwest into the national economy.
The 1891–92 viaduct also reflects the confidence of Gilded Age engineering. This was the era of great iron and steel bridges, when American builders were proud to cross gorges that would once have stopped a railroad cold. A bridge that briefly ranked among the highest in the world, built in a remote corner of Texas, shows how far that ambition reached.
The 1944 bridge tells a wartime story. During World War II, the federal government controlled steel and other scarce materials, and a project got approval only if it served the war effort. Approval for this bridge shows that this lonely crossing mattered to the nation's ability to fight.
If you visit
This is wide, open country, and much of the experience is simply the land itself: rugged canyon walls, desert scrub, and a big sky over the place where two rivers meet. Picture the gorge before the reservoir raised the water, and the trains that once crept down into it and out again through tunnels.
If the railroad bridge is in view, watch for a passing train. Seeing a modern freight train cross a span that was built for the wartime rush helps you understand why this crossing has always mattered. Respect railroad property and stay off the tracks and the right-of-way.
The Pecos crossing makes a natural stop on a drive across the Texas borderlands near Del Rio and the Amistad area, where the canyon country and its long human history are well worth exploring. Services can be far apart out here, so plan for fuel and water before you set out.

Dryden Intermediate Field Site 29
Dryden, TX
Aviation came early to remote Terrell County: in 1919 the U.S. government built an airfield near Sanderson for the 90th Aero Squadron, whose biplanes patrolled the Mexican border. When World War II demanded a chain of civilian and emergency military fields across the Southwest, American Airlines and federal aviation authorities built this landing field, finishing its two mile-long rock-asphalt runways in October 1943. Later renamed Terrell County Airport, it went on to host civil air patrol and military training.
The Pecos River in Literature and Folklore
Langtry, TX
Rising in the mountains of northern New Mexico and cutting through some of the harshest country in Texas on its way to the Rio Grande, the Pecos River became a boundary in more ways than one. To 19th-century travelers it marked the edge of the tame world—"west of the Pecos" meant a land of flash floods, mineral-heavy water, and hard-bitten reputations. Writers and folklorists from J. Frank Dobie to Zane Grey turned that reputation into legend, and the country gave rise to figures both real, like Judge Roy Bean, and mythical, like Pecos Bill.
Site of Vinegarroon
Langtry, TX
In 1882 the Southern Pacific faced its last great barrier—the Pecos River canyon—on the transcontinental line linking New Orleans and San Francisco. Beside the excavation of Tunnel No. 2 rose Vinegarroon, a rough camp named for a local scorpion and home to thousands of mostly Chinese laborers. Roy Bean ran a saloon and served as justice of the peace here until the rails were joined in 1883 and the camp was abandoned.
Near Site, Southern Pacific Ceremony of Silver Spike
Del Rio, TX
On January 12, 1883, near the Pecos High Bridge, two great railroads met and were joined by a silver spike, completing a transcontinental line across the Southwest. The eastern portion had begun in 1850s Texas and was rechartered in 1870 to link Houston and San Antonio to the Rio Grande, while C.P. Huntington drove the Southern Pacific eastward from California. When Huntington and Texas magnate T.W. Pierce reached agreement, their tracks closed the gap.
