The 25th of April bridge was originally named for Portugal's right-wing dictator, Antonio de Oliveira Salazar, who ruled from 1932 to 1968. After Portugal's 1974 revolution, residents who supported the revolution started calling the bridge the 25th of April bridge to celebrate the change in power on April 25, 1974. Citizens loyal to Salazar's party continued to call it the Salazar bridge, and those who didn't want their politics known just called it "the bridge over the river".
