Segmental Bridge Construction

Like stationary wooden forms that are used to shape concrete for bridge abutments, curbs and retaining walls (to name a few), form travellers are pre-assembled forms used to construct segmental bridges.

Segmental bridges, like this one, are constructed using many shorter segments whereas a more traditional bridge is constructed in large segments using girders. 

Segmental bridges are often used when long spans are required or when access to the site is limited.

Deck Pour Preparation

The truss screed – named because of its triangular shape – is installed, signaling the bridge deck is ready for concrete.

Screeding is the process of flattening and smoothing wet concrete. The truss screed is mounted on rails on either side of the bridge deck, and a screed attachment will be suspended from the truss allowing it to move back and forth to level and finish the concrete.
