Hi Angela
I think this is the specific term

Agli inizi degli anni 50 Ulrich Finsterwalder (1899-1987) progetta e realizza sul fiume Lahn a Balduinstein, in Germania, il primo ponte costruito a sbalzo per *conci successivi* gettati in opera. Questa tecnica consente di realizzare impalcati in c.a.p. senza l'ausilio di centine poggiate a terra, svincolandosi cosi' da tutti gli impedimenti sottostanti e dall'altezza dal suolo
(...)
I primi ponti a sbalzo avevano tutti i conci gettati in opera. L'idea di impiegare conci prefabbricati si deve ai francesi che nel 1962 costruirono il ponte di Choisy-le-Roi sulla Senna, progettato da Jean Müller, allievo di Freyssinet.

As its name implies, a segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then tranported to their final location for placement in the full structure).
The first *segmental concrete bridge*, built in 1950, was cast-in-place across the Lahn River in Balduinstein, Germany. The first *precast segmental concrete bridge*, built in 1962, crossed the Seine River in France. (FHWA 2003)
