Using the example of the Ile Falcon bridge in Switzerland, this paper shows how incremental launching can be used successfully to construct a bridge with complex geometry. This road bridge crosses the River Rhone in the mountainous Valais region of Switzerland.

It has two parallel curved bridges, each about m long, and with very similar design and construction. Construction of the north bridge began in Spring and ended in Summer ; completion of the south bridge is scheduled for Summer This paper concerns the north bridge whose design was influenced strongly by the decision to use incremental launching for its construction.

Its superstructure is a prestressed concrete box girder bridge with 15 spans, whose girders are supported by short circular piers. To prevent scouring, the piers in or near the Rhone river bed are founded on hollow shafts. The project required an unusually complex girder geometry for an incrementally launched bridge.

The paper shows that acceptable longitudinal and transversal distortions can be designed and explained in the design of the launching prestressing. It considers the effects of various systematic errors, and rotation errors are shown to compound despite match casting.
