Manterola was particularly known for his work as a bridge designer of the engineering firm Carlos Fernández Casado.
Another of his most important designs is the Engineer Carlos Fernández Casado bridge on the AP-66 which spans a part of the Barrios de Luna reservoir in León, which was a world record for a decade in several categories and is still the second longest span in Spain, after the above-mentioned La Pepa Bridge.
Designer of many bridges in Zaragoza, Manterola designed the Manuel Giménez Abad Bridge for Zaragoza's third ring road (Z-30) and the Barranco de la Muerte aqueduct, structure for the Canal Imperial de Aragón to span the previously mentioned Z-30.
For the Expo 2008, Manterola designed a pedestrian bridge called Pasarela del Voluntariado.
