Chapter 4: The Construction Process of Segmental Bridges
segment geometry, especially depth, remain possible with relatively little effort. Disadvantages of cast-in-place cantilevering with form travelers are discussed in Section 220.127.116.11. Figure 4-4 shows a typical view of a form traveler.

Form travelers consist of a sufficiently stiff steel frame to which form panels for the box girder segments are attached at the front. According to Levintov (1995, p43), the steel frame is mostly composed of two parallel “diamond- or triangular-shaped frames that are connected and stiffened
