The present paper deals with the economic optimization of a series of 15 bridge piers with rectangular hollow sections. It combines height columns of 20, 30, 40, 50 and 60 m and viaducts of 40, 50 and 60 m of main intermediate spans. The optimization uses a variant of the ant colony method. Results show the variation in geometry, concrete quality, reinforcement and cost, both in the footings and in the main column, as the columns gain height and the viaducts grow in span length.
