Incremental launch bridge construction Incrementally-launched bridge construction Itz Valley Bridge near Coburg. Incremental launch is a method in civil engineering of building a complete bridge deck from one abutment of the bridge only, manufacturing the superstructure of the bridge by sections to the other side.

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 ...
In 1873, Frenchman Joseph Monier obtained a French patent for a method of iron-wire reinforced concrete bridge construction; [5] his first iron-wire reinforced concrete bridge was constructed across the moat of the marquis de Tillièrein's fr:Château de Chazelet, in 1875.

Underslung (lower-beam) movable scaffolding system used during construction of the Aurachtalbrücke Emskirchen [] (2015). A movable scaffolding system (MSS) is a special-purpose self-launching form used in bridge construction, specifically prestressed concrete bridges with segments or spans that are cast in place.
Prestressed concrete is a major advance in concrete engineering and has effectively been used in rigid frame bridge construction. [10] This is notable because it was already challenging to place standard reinforcing in a concrete rigid frame bridge. Prestressing the rebars is more difficult but was proven to still be feasible. [10]
The alliance with steel gave birth to reinforced concrete, allowing the construction of increasingly daring and economical structures. Paul Séjourné would be the last great theorist of masonry bridges, and his methods and formulas for calculating piers remain relevant today. [6] Piers then became more slender and taller.
