Bridge Construction Techniques - Through Truss Bridge

The easiest construction technique is in situ during the dry season, over causeway and culverts. We advise too much camber, leaving gaps in the top chord, which close when the causeway is removed.

Truss built in situ on home bank, then craned to half way. The entire bridge is then lifted into position with large cranes on both banks. Good for small, light bridges when large cranes are also available.

Roller launch method. The bridge is constructed in situ and then jacked across the span using rollers and cantilever technique. A temporary nose section is used this is removed once the bridge is in place.
