El Puente de la Pólvora (Spanish for the Black-powder Bridge) was a metallic bridge with stone abutments spanning the Segura River. The structure was completed with five stone arches on the left side of the bridge designed to span the river flood plain. Built between 1870 and 1877 in the vicinity of Javalí Viejo and Alcantarilla, in the Región de Murcia (Spain), the bridge was designed by the civil engineers Manuel Pardo Sánchez-Salvador (for the stone structure) and José Caunedo Sánchez (for the metallic structure). Both structures were built by Pedro Díaz Sánchez y Francisco Peña y Baquero respectively.
