The Rio Grande serves as the focal point of this borderlands region, winding between Texas and Mexico near the community of Roma. The town’s significant heritage is anchored by the Roma Historic District and the Roma-San Pedro International Bridge, which connects the United States to Ciudad Miguel Alemán. To the west, the river creates unique geographical features such as Fronton Island near the settlement of Fronton.
