Manuel del Valle Arévalo (10 November 1939 – 26 March 2020) was a Spanish lawyer, politician, and member of the Spanish Socialist Workers' Party (PSOE) who served as Mayor of Seville from 24 May 1983 until 30 June 1991. Del Valle is credited with redesigning and transforming Seville's modern urban infrastructure in preparation for the Seville Expo '92. His major achievements included the construction of the Seville-Santa Justa railway station and a new railway layout within the city, the ring road and other new highways, and a series of new bridges, including the landmark Santiago Calatrava-designed Alamillo Bridge.
