Situated just 25 miles (40km) from the mouth of the Rio Grande (Rio Bravo del Norte) on the Gulf of Mexico, the binational cities of Matamoros and Brownsville anchor the extreme east of the Mexico-U.S. international border. Brownsville – on the southernmost tip of Texas – and Matamoros – itself near the extreme northeast point of Mexico in the state of Tamaulipas – form a classic example of a cross-border sister city community, although in recent years the rise of narco violence on the Mexican side and the U.S. government’s desires to build more border walls in this area have gotten more attention than the rich bicultural histories of these cities. Today we will better appreciate some of this historical heritage by exploring a common, but extremely significant symbol in the Mexico-Texas border region: the symbol of the international bridge. In crossing the Gateway International Bridge (or Puente Nuevo/New Bridge) between Matamoros and Brownsville we will dust off the cob webs of another chapter in the cross-border history of Mexico and the United States.
Previously when commemorating the 170th anniversary of the signing of the Treaty of Guadalupe Hidalgo we journeyed to the far western corner of the new border that the peace agreement between the U.S. and Mexico created. Surrounded by hills and beach-going crowds on the Mexican side, Boundary Monument 258 marks the U.S.-Mexico border between the corners of Tijuana and San Diego. At 258, it is the highest numbered boundary marker along the land portion of the U.S.-Mexico border which begins with Boundary Monument 1, located 700 miles to the east just outside of Ciudad Juárez-El Paso. Unlike the busy, tightly-controlled scene at Playas de Tijuana/Friendship Park, Boundary Monument 1 is in a hidden canyon along the Rio Grande and without major fence barriers. If, as some border artists have asserted, boundaries are scars on the Earth , this is where the wound across the desert begins.
