The roadside stories worth pulling over for.

Marker Inscription

Site of a ranch settlement, owned by Don Rafael Garcia, called "El Fronton de Santa Ysabel" (Bluff of Saint Isabel) about the year 1828. The Mexican custom station was located here in 1844, after the villages of Brazos Santiago and Boca Del Rio were swept away by storms. Goods landed here were at once freighted inland to Matamoros. After the Mexican War (1846-1848), the United States Post Office of "Point Isabel" was created on April 9, 1849. Efforts to build a railroad line to Brownsville in the 1850s did not succeed, but after the Civil War, in 1866, public demands for a rail line to Brownsville were met by Rio Grande steamboat interests, who chartered but refrained from building the road. In 1871, competitors formed the Rio Grande Railroad Company, obtained a charter, and put the line into service in 1873 from Brownsville to a terminus here (450 feet south of this marker). The line served until 1933 when a deep water channel was built to Brownsville.
