Spiderweb Railroad
Mission, Hidalgo County, Texas
Marker Inscription
Begun in 1912 when dirt roads hampered area transportation, the San Benito & Rio Grande Valley Railroad was instrumental in the early development of the region's towns and commerce. It grew from the Brownsville Street and Interurban Railroad Company, established by Sam A. Robertson (1867-1938), a local civil engineer and land promoter. As the line grew and spurs were constructed to remote frame communities, it became known as the Spiderweb Railroad. With just over 100 miles of track, the company became part of the Missouri-Pacific system in 1924. (1982)

The Story
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.
Why it matters
This tangle of rails opened the Valley's remote farming settlements to commerce, showing how local railroads stitched together the development of an entire region.

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.
Former Hidalgo Post Office
Hidalgo, TX
Built in 1889 to house a general merchandise store, this modest building set aside one corner for the town's postal service — a common arrangement on the Texas frontier, where the store was the heart of a community. It served as Hidalgo's post office until 1913, with storekeeper William Odell, his wife Josephine, and Gumaro Rodriguez among those who kept the mail moving. It is celebrated as the oldest surviving post office building of its kind.
Hidalgo Irrigation Pump Plant
Hidalgo, TX
Until the early 20th century, the semi-arid Lower Rio Grande Valley was fit mainly for cattle grazing. In 1909 a steam-powered pump rose here to lift Rio Grande water onto some 40,000 acres, and expansions in 1911–12 by the Louisiana-Rio Grande Canal Company carried irrigation to the Pharr-San Juan-Alamo district. Sold to a county water district in 1920, the plant kept pumping until an all-electric station replaced it downstream in 1983.
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.
