In 1958 and with the fall of Pérez Jiménez, Sucre Figarella was named Governor of Bolivar by new president Romulo Betancourt.
From this position, Sucre pushed forward many important works such as the Angostura Bridge in Ciudad Bolívar, the General Rafael Urdaneta Bridge in Maracaibo, the Araña highway distributor, the Tejerías-Caracas highway, the Guri Dam in Bolivar, the famous Cota Mil in Caracas as well as pushing forth works on the Caracas Metro and the expansion of the Simón Bolívar International Airport among others.
He also expanded the production capacity of Sidor, Ferrominera, Venalum, Alcasa and Interalumina and created Bauxiven, Carbonorca, Proforca, Remorca and other important companies.
Some, such as newspaper columnist José Ignacio Acevedo, consider Sucre Figarella's infrastructure construction to be the most useful and expansive during the whole of the democratic period in Venezuela.
