Gonzales-San Antonio Road
Gonzales County, Gonzales County, Texas
Marker Inscription
Shortly after he established his colony along the Guadalupe River in 1825, Green Dewitt ordered that a road be built between his capital city, Gonzales, and San Antonio. Byrd Lockhart surveyed the road and opened it in 1827. Eighty miles long and running past three watering holes, settlers and Mexicans used it for travel and trade, though the presence of native groups in the area made traveling dangerous. Mile markers were carved into oak trunks along the route. During the Texas War for Independence, Stephen F. Austin, William B. Travis, and Jim Bowie used the road, as did the Immortal 32, who marched from Gonzales to the Alamo. Santa Anna also marched his army along it after the battle of the Alamo.

The Story
When Green DeWitt planted his colony on the Guadalupe River in 1825, he ordered a road cut to link his capital at Gonzales with San Antonio, and surveyor Byrd Lockhart opened the eighty-mile route in 1827—its mileage notched into roadside oak trunks. Settlers, traders, and Mexican travelers braved the road despite the danger of raids. A decade later it became a thoroughfare of the Texas Revolution: the 'Immortal 32' marched down it from Gonzales to reinforce the Alamo, and Santa Anna's army followed after the fort fell.
Why it matters
This frontier road tied together the scattered settlements of Anglo-Mexican Texas and became a corridor of the revolution that turned a Mexican province into the Republic of Texas.
The story behind this marker
AI contextThe era
In the 1820s, the stretch of prairie between the Guadalupe River and San Antonio was the far edge of a young Mexican nation's northern frontier. Mexico had recently won its own independence from Spain, and to fill and defend this thinly settled land it invited empresarios—colonization agents—to bring in families and put down roots. Green DeWitt was one of them, and in 1825 he planted his colony along the Guadalupe, naming its capital Gonzales after a Mexican governor.
A colony on paper is not a colony in fact until people can reach it. The nearest town of any size was San Antonio, the old Spanish presidio and mission settlement that served as the region's hub of trade, government, and military strength. Between the two lay open country with no reliable road—only the distance, the rivers, and the water you could or couldn't find along the way.
So almost as soon as he arrived, DeWitt ordered a road built to tie his new capital to that older center of power. It was the kind of decision that defined frontier survival: without a dependable route to markets, garrisons, and neighbors, a settlement withered. With one, it had a chance to grow.
People & events
The man who turned the order into a road was Byrd Lockhart, a surveyor who laid out the route and opened it in 1827. It ran some eighty miles and was threaded past three watering holes—the spacing that mattered most to anyone crossing dry country with animals and wagons. In a nice touch of frontier ingenuity, the distances were carved directly into the trunks of oak trees along the way, a living milepost system for travelers who had no maps.
For its first years the road did ordinary, essential work. Settlers and Mexican travelers used it to move goods and visit one another, knitting scattered homesteads into something like a community. It was never safe—the presence of Native groups who contested this land made every journey a gamble—but it was used because it had to be.
A decade after it opened, the road found itself at the center of a revolution. As Anglo and Tejano colonists broke with the Mexican government, figures central to that struggle traveled this route—Stephen F. Austin, the most prominent of the empresarios; William B. Travis; and Jim Bowie. Most memorably, the small band remembered as the Immortal 32 marched down this road from Gonzales to reinforce the besieged Alamo. And after the fort fell, the same road carried Santa Anna's advancing army deeper into Texas.
Its place in the American story
The story of American expansion is often told through its great trails, but the humbler local roads did the quiet foundational work. A colony road like this one is where the abstract idea of 'settling the frontier' became the concrete reality of a wagon, a family, and eighty miles of prairie between you and the nearest town.
It also captures something essential about early Texas: this was a place where Anglo settlers, Tejanos, and Mexican citizens shared the same roads and the same dangers under the same government—until they didn't. The road that once served everyday travel and trade became, almost overnight, a corridor of war. The same ruts that carried cotton and news carried soldiers marching toward the Alamo.
That transformation—from a Mexican province stitched together by frontier roads into an independent republic, and eventually a part of the United States—is one of the pivotal turns in the story of the American Southwest. This road was one of its physical arteries.
If you visit
Stand here and the first thing to do is picture the emptiness. There were no fences, no highways, no towns on the horizon—just grass, sky, and a single cut track running toward San Antonio, with the next drink of water hours away.
Look for the country itself as the artifact. The oak-trunk mileposts are long gone, but oaks still stud this landscape, and it takes little imagination to see a traveler pausing beside one to read a distance notched into the bark. The land tells the story better than any monument could.
This is a natural anchor for a Texas Revolution road trip. Gonzales—home of the famous 'Come and Take It' flag—sits at one end of the historic route, and San Antonio and the Alamo at the other. Driving between them today, you're loosely retracing the path the Immortal 32 walked toward the fight, which turns a stretch of ordinary highway into something worth slowing down for.

Cibolo Crossing on the Gonzales Road
La Vernia, TX
Under Mexican rule, the Gonzales Road linked the DeWitt Colony settlement of Gonzales to San Antonio de Béxar, fording the Cibolo Creek at a natural crossing about twenty-two miles east of the town. That ford ran through land granted to spy Erastus "Deaf" Smith, who is said to have watched Mexican troops from a nearby tree in 1835. The crossing became a rendezvous during the Texas Revolution, where relief forces under captains like Juan Seguín and Albert Martin gathered in early 1836 hoping to reinforce the Alamo, before annexation and new roads left the old ford abandoned.
Sandies Chapel Cemetery
Nixon, TX
This burial ground began with the family of Joseph and Catherine McCoy, pioneers of Green DeWitt's colony, and later served the Sandies Chapel community, with graves reaching back to the 1860s. Among those laid to rest here are a San Jacinto veteran, citizens of the Republic of Texas, Civil War soldiers of the local home guard, and four pioneer Methodist ministers. In one small plot lies a cross-section of early Texas history.
Rancho
Nixon, TX
Rancho grew up around Paul Murray's country store, opened in 1849 at the crossing of roads to San Antonio, Gonzales, Seguin, Cuero, Goliad, and Indianola. Murray's fellow Mississippians followed him west for farmland but soon traded the plow for the saddle amid the free-ranging cattle of the open country, and the settlement took its Spanish name as a ranching culture took hold—some of Texas's earliest range branding codes were devised here in 1866. The town thrived with stores, a school, and two churches until 1906, when the railroad bypassed it for nearby Nixon and Rancho's buildings and people drifted away.
Site of Old Town of Union Valley
Nixon, TX
Settled in the 1860s, Union Valley grew around a log schoolhouse donated in 1872 that also served as Masonic hall, church, and courtroom — the multipurpose civic heart of a frontier settlement. A post office opened in 1883, and stores, cotton gins, saloons, and smithies bearing a roll call of pioneer family names lined its streets. Like so many rural towns, it faded after the Galveston, Harrisburg & San Antonio Railroad bypassed it in 1906.
